Atom And The Atoms Of Atoms

For the lesson observed the objectives was to explain the trends of the periodic table based on the elements’ valence electrons and atomic numbers. Additionally, students were responsible for applying their previous knowledge in calculating subatomic particles to review the Bohr Models and discus the relationship among families in the periodic table. Students will use the information from today’s lesson to make future judgments on reactivity and bonding created during chemical reactions in the next unit. Lastly, students were to connect the information on elemental properties to previous experiences with their health, commercial products, and everyday life.

The students created a macroscopic, three-dimensional (3D) model of several properties of the periodic table. They explained in their own words the following terms: atomic radii, ionic radii, first ionization energy, and electronegativity. Lastly, they identified, described, and explained the patterns observed in the 3D periodic tables for the following element properties: atomic radii, ionic radii, first ionization energy, and electronegativity.

Apply: Atoms are most stable when their outermost shell is full. If their outermost shell is not full, atoms tend to gain, lose, or share electrons until the shell fills up. While doing this, atoms react and form chemical bonds with other atoms.

a. atoms lose electrons if they have just one or two electrons in their valence shells; they gain electrons if they need just one or two electrons to complete the valence shell as in K+CL- __Ionic bonds_

Elements with atomic numbers greater than iron’s atomic number form during the formation of a supernovae, also known as a mini-bang. The process begins when a massive star has depleted its supply of magnesium and silicon, and only has a bare iron ore remaining. Now, the star no longer has the energy to maintain its immense mass against the force of gravity, and as a result, the entire star collapses. This process fuses together electrons and protons in the core, which forms neutrons. After neutrons build up in the ore, the star recoils in the form of an explosion. During the explosion, the neutrons attach to iron atoms in the ore, and begin converting back to protons and electrons. As a result, iron atoms are able to become different elements with greater atomic numbers.

Atoms have a tendency to either lose, gain, or share electrons until the atoms is surrounded by eight valence electrons. For an atom to have a full valence shell of electrons a chemical bond will share or transfer electrons in order for this to happen. The three types of transfer between electrons and elements are ionic, covalent, or metallic.

The modern atomic theory explains the characteristics of atoms such as protons, neutrons and electrons. The number of protons show how many positively charged ions, the number of electrons show how many negatively charged ions, and the number of neutrons shows how many neutrally charged ions are in an atom. Adrenaline, or C9H13NO3, contains carbon, hydrogen, nitrogen and oxygen. The carbon ion has a positive partial charge, while oxygen

Describe atomic structure. Whether or not the atom is positive or negative, the ions orbiting around the atom.

Now that we know how atoms lose electrons, how do atoms gain electrons? When atoms gain electrons it usually has more than 4 valence electrons. This transforms a atom from a neutral state to a negative state therfore turning the atom

Because protons have a charge of +1, and electron have a charge of -1, an atom has an equal number of protons and electrons, making it electrically neutral. Atoms can lose or gain electrons, however, to gain a full valence (outer shell) of electrons. When this happens the atom becomes an ion, and it is no longer electrically neutral. As the element of an atom is governed by the number of protons in the nucleus, the ion is still the same element as the atom it came from.

Everything that exists in the world is made up of atoms, from the asteroids that float around in space to the very cells inside a human body. Atoms are everywhere and that’s because atoms make up everything. Atoms are made up of protons, neutrons and electrons, each element has different amount of protons, neutrons and electrons. For instance one Helium atom has two protons, two neutrons and two electrons. Helium is an extremely stable element so there are no variations such as ions or isotopes. So we know that atoms make up everything in the universe and atoms are made up of protons, neutrons and electrons. So what makes protons, neutrons and electrons?

An Atom is the the basic building block of all matter. Atoms are made up of Particles, called: Protons, neutrons and Electrons. Protons carry a positive charge, the neutron carry 's a neutral charge and the electron carry’s a negative charge. The Atom has two main parts the Nucleus and the Electron Shell. The Nucleus contains the Protons and Neutrons. The electron Shell Contains the The electrons.

In chemistry and physics, atomic theory is a scientific theory of the nature of matter, which states that matter is composed of discrete units called atoms. It began as a philosophical concept in ancient Greece and entered the scientific mainstream in the early 19th century when discoveries in the field of chemistry showed that matter did indeed behave as if it were made up of atoms.

Matter is anything made up of atoms and molecules and the study of these “things” called atoms dates back to the time of Ancient Greece to the present. The information about atoms known today is certainly much greater than what was known centuries ago. First, there was only hypotheses on this idea that everything in the world is made up of tiny, unseeable particles. As technology advanced, these hypotheses were tested, critiqued, modified, and built upon. A mass of knowledge is known regarding atoms, thanks to the research of numerous chemists and physicists. The atomic theory is the building block to the study of matter just as the atom is the building block to all matter.

The atom is the building block of every known physical element in existence. Every solid, liquid, gas, plasma has either neutralized or ionized particles. Atoms are tiny in size at around 10 billionths of a meter. The majority of the particles’ mass is the nucleus. The protons possess a positive charge, while electrons have a negative electric charge and neutrons have no electric charge. The atom is the fundamental unit of every element that has the chemical components of the element, consisting of a nucleus, a particular combination of neutrons and protons, and has one or more electrons bound to the core by an electrical charge.
