Atom Essay

* Protons and electrons have equal and opposite electrical charges. Protons are positively charged, and electrons are negatively charged.

13. What are the subatomic particles and what is the electrical charge of each? Protons (positively charged), Neutrons (electrically neutral), both found in the Nucleus of the atom & Electrons (negatively charged). Where in the atom is each of these particles found? In the orbital (Electrons)

Strong nuclear force is the force that binds together the protons and neutrons in an atomic nucleus. In other words, it holds together everything we know in the universe. Out of all of the fundamental forces, strong nuclear force is the strongest.

1. Predict: Positively charged protons in the nucleus of an atom are attracted to negatively charged electrons.

Alpha: is a helium nucleus and is made up of 2 protons and neutron and has a positive charge. When it is ionizing it can knock out the electrons because of the collisions.

One of these properties is called an electrical charge. Protons have a "positive" (+) charge, electrons have a "negative" (-) charge, and neutrons have no charge, they are neutral.

In the nucleus of an atom there are protons and neutrons the number of protons and neutrons depends on the element and ,if it is an isotope of that element. E.g. carbon 12, carbon 12 has six neutrons six protons and 6 electrons . Electrons are located around the nucleus of the atom. Electrons are in shells, the shell closest to the nucleus is 1 , the one after 2 and so on. Each shell can only hold up to a certain number of electrons . the first can hold up to 2 , the second 8 (2+6) the third up to 18 (2+6+10). The general formula for finding out how many electrons a shell can hold is 2n^2. Electrons have a negative charge , while protons have a positive and neutrons have no charge. A atom has the same number of protons and electrons. An ion is formed when an atom loses or gains a electrons .

To understand how this electricity works we must start with the basics. The atom is the smallest unit of matter, consisting of protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Electric charges that are the same repel each other and charges that are different attract each other. Electric charges can exist alone, unlike magnetic poles.

It starts with subatomic particles, such as protons and electrons, produce electrical fields. These relating electrical fields are composed primarily of electrons,

As the size of the negative ion and the charge on the positive ion both increase and the size of the positive ions decrease, the polarisation effect increases. This polar ionic bonding gives many of the atoms covalent characters. Sometimes one of the atoms become so highly polarised that they share the electrons and therefore can create covalent bonds. Covalent bonding takes place where two atoms have a single, unpaired electron in an atomic orbital; these orbitals will therefore overlap so that the two atoms are sharing a pair of electrons. The attraction that holds the atoms together is the force between the electron and the nuclei in each of the atoms.

An atomic particle is like a cell and nucleus is the control center of the cell. The nucleus is where the mass of the atom and all of its subatomic particles is concentrated.

What is an atom? An atom is the basic building block of everything. An atom is made of electrons protons and neutrons and the number of protons determines the element. Back in the 1800’s this whole idea was unknown. In the 1800’s steam was starting to power everything. It became important to know how steam works, so you can learn to use it more effectively. It was this idea that drove Dalton to research the atom.

An ion is an atom that is both has a positive and negative charge. The attraction of oppositely charged ions to one another is an ionic bond. Table salt is a very good example of an ionic bond.

The atom is a unit of matter, the smallest unit of an element, consisting of a dense, central, positively charged nucleus surrounded by a system of electrons, equal in number to the number of nuclear protons. It consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All electrons bind to the nucleus through an electromagnetic force. A ground of electrons bound together form individual molecules. An atom with an equal number of protons and electrons will hold a neutral charge. An ion has either a positive or negative charge because of a lack of electrons or an electron excess. The number of protons determines the

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.
