Atomic Structure and Period Table

LIST TWO OF THE FOLLOWING…

Alkali Metals: Lithium (Li), Sodium (Na)

Alkaline Earth Metals: Calcium (Ca), Barium (Ba)

Halogens: Chlorine (Cl), Iodine (I)

Noble Gases: Helium (He), Neon (Ne)

Transition Metals: Titanium (Ti), Gold (Au)

Non-Metals: Hydrogen (H), Carbon (C)

Metalloids: Boron (B), Silicon (Si)

The overall structure of the periodic table can be explained in vertical columns and horizontal rows. Groups (otherwise called families) make up the vertical columns. These elements have similar chemical properities. Periods make up the horizontal rows. Elements are categorized from having metallic properties to nonmetallic properties. The ones that have metallix properties are located on the left, and the ones that have nonmetallic properties are located on the right.

According to our class slides, the ground state is when electrons are in their lowest state of energy. The excited state is caused by a flame or other source. This energy source gets absorbed by electrons, causing them to be in a higher state of energy. In this heightened state of energy, it emits a photon of energy, which is seen as light. (This is explains how colors of fireworks arise.) Different elements produce different colors when they are excited because it depends on the amount of energy that is released from the electron.

The overall volume of an atom is located in the nucleus, which contains all the protons and neutrons of an atom.

To make an isotope for one of my models, I would need to change the amount of neutrons, by either adding or remocing one. This would change the necleus of my atom.
