Structure Of The Atomic Structure

The chemical properties of group 1: all the elements in the group one have only one electron which happens to be outer energy level. However group one are white solids and this means that they will easily dissolve in water. In addition group one are all on the left side of the periodic table which means that they are all alkali and alkali metals form alkaline compounds. However this will mean that all the metals have similar properties to one on other.

Alloys are made up of two different chemical elements, most of which are metal. There are some non metal alloys components such as the various forms Hydroxides and Carbonates. The most important metallic component of an alloy is called a main metal, parent metal and the base metal. The other component of an alloy can be either metal or nonmetal. Although alloys can be a compound, they are usually a solid solution.

The atoms are bound by shared electrons in a covalent bond. Even though they share electrons, they do not share them equally. Even though most of the time covalent bonding occurs between nonmetals, there have been times where this type of bonding occurs between a metal and a non metal. Covalent bonds are most likely to occur when molecules have a similar electro negativity level (Gray 76). Elements follow the octet rule because they are the most stable when they have eight electrons in their outer shell. Therefore, by sharing those electrons they fulfill the octet rule and the noble gas configuration. Another way covalent bonds satisfy the octet rule is too form single, double, and triple bonds. It’s easy to differentiate between those bonds, for example a single bond is when two atoms share one pair of electrons, a double bond is when two atoms share two pairs of electrons, and a triple bond is when two atoms share three pairs of electrons. Bond order and length are used to describe the strength of covalent bonds; they both have a direct relationship. Bond order is the amount of bonded pairs between two atoms. Bonding length is the distance between two covalent bonds. Compared to ionic bonds, covalent bonds are have a lower melting and boiling point. They are also less likely to dissolve in water. Not all the pairs of the molecules have the same characteristics. When a pair is not sharing any electrons, that pair is called a lone pair. When a pair is sharing electrons, they are called a bond pair. And finally, a Lewis dot structure is a great way to illustrate a covalent

1778 – Antoine Lavoiser distinguished the elements into 4 categories: metals, non-metals, elastic fluids (gases) and earths. This was the first classification of the elements.

(20) Metals are classified variously—according to molecular weight (“heavy metals”), according to chemical properties (periodic table), according to toxicology. Please do the

If I was a forensic scientist and I was trying to identify a substance as either a metal or nonmetal I would use certain tests to determine the classification of my substance. I can characterize metals and nonmetals because they both contain different properties.

The periodic table was a display of all known elements ordered in increasing atomic number. The modern periodic table has groups, a column of elements, and periods, a row of elements. Elements within the same group have similar chemical properties because they all possess the same amount of electrons in the highest occupied energy level, also known as valence electrons. Due to the fact that chemical properties are determined by electron configuration, elements in the same group will react similarly. This was because elements in the same group want to lose or gain the same amount of electrons, in order for them to become stable ions. For metals, the elements lose electrons in order to become stable ions and nonmetals gain electrons to become stable ions. All the elements in a group will

Some physical properties of metals include luster, strong ampere, high density, high melting points, and being very ductile and malleable. Some physical properties of nonmetals include poor luster, poor ampere, brittle, low density and melting point, and not being very ductile or malleable. Chemical properties of metals include having electron that are easily lost, and corroding easily. Chemical properties of nonmetals include easily gaining electrons and are good oxidizing agents. Metalloids have properties of both metals and nonmetals. There is only one classification of metalloids, and there are only seven elements within that classification. Within metals there are alkali metals, alkaline earth metals, lanthanoids, actinoids, transition metals, and post transition metals. Within nonmetals there are halogens, noble gases, and other nonmetals. All of these are organized within the periodic table (Dayah,

The element I have chosen for my element fact sheet is copper. The mass number for copper is 63,546 the atomic number for copper is 29 its in group eleven the classification is solid. copper is a transition metal. Copper's boiling point is 1,358k, melting point is 2,835k and it doesn’t have a freezing point.

Provide three properties of the metal you chose in question 3. Explain two of those properties in terms of the metallic bonding model.

In conclusion, the relationship between the electron arrangement of elements and their position on the periodic table have two attributes in which include The number of occupied shells is the same as the period number. As well as, the number of electrons in the outer shell is equivalent to the group

According to the periodic table Mendeleev created, he organized the elements in rows and groups based on the atomic number. In addition to this table, the periodic law was created by the scientist, Henry Moseley. This law stated that an element's properties are the mechanisms of its atomic number. The periodic table is structured in certain ways. In a period, the atomic radius decreases as the atomic number increases from left to right. Also, from moving from left to right, the number of protons increases as well as the electrons because the positive charge increases in the nucleus causing the strengthening of its attraction toward electrons. On the contrary, the atomic radius increases in a group moving down with the increase of protons and electrons as well.

Second, all atoms of a particular element are identical. Third, atoms of different elements have different properties. Fourth, Atoms cannot be destroyed nor created. Fifth, in a chemical reaction, atoms link to one another, or separated from one another. Finally, atoms combine in whole number ratios to form compounds (Famous Scientists).

Engineering materials is classified into families based on their material structure, compositions, properties etc, as shown in the figure:

Many miniaturized electronics use thin films. Thin films are metals where the width is larger than the thickness. It is extremely important to understand the properties of thin films in order to use them effectively in electronics. One of the important properties is texture of the film because it determines the reliability of the metal. The texture of a film is determined by the orientation of the cubes. Metals such as silver, copper and nickel are all face-centered cubic. What that means is that the atoms are arranged in a way that it form a cube with an atom in the center of each side (as shown in figure 1). Multiples cubes bonds together which
