Atoms

The small things that make up almost everything.

2

Neutron

A subatomic harden particle with the symbol of n or nO. It has no electric charge and a mass larger then a proton.

3

Proton

A subatomic particle with a symbol of p+ or p. It has a positive electric charge and one elementary charge.

4

Nucleus

The center of a cell.

5

Orbitals

A mathematical function that describes the wave-like behavior of either one electrons or a pair of electrons in an atom.

6

Isotope

Each of the two or more elements that contain equal numbers of protons but different numbers of neutrons in their nuclei.

7

Cation

A positively charged ion.

8

Anion

A negatively charged ion.

9

Atomic Number

The number of protons in an nucleus of an atom.

10

Atomic Mass

A mass of an atom expressed in atom mass unit.

11

Alkali Earth Metals

Metallic elements found in the second group of the periodic table.For example Beryllium, Magnesium, Calcium,Strontium,

12

Halogens

Five non-metallic elements found in group 17 of the periodic table. For example Florine,Chlorine Bromine,

13

Noble Gases

Helium,Neon,Argon,Ununoctium,

14

Lanthanides

Any of the series of fifteen metallic elements from the periodic table.For example Praseoderium, Neodymium.

15

Actinides

Any of the series of fifteen metallic elements from actinium.For example Thorium,Protactinium.

16

Metals

An element, compound, or alloy that is a good conductor of both electricity and heat.

17

Non-Metals

The elements in groups 14-16 of the periodic table.For example,Carbon,Phosphorus,Nitrogen.

18

Semi-Metals

Meitnerium,Darmstadtium,Roentgenium,

19

Transition Metals

The 38 elements in groups 3 through 12 of the periodic table. For example Zinc, Molybdenum, Cadmium Scandium,

20

Electrons

Negatively charged particles of atoms. Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus.

21

Acid

A chemical substance (typically, a corrosive or sour-tasting liquid) that neutralizes alkali's, dissolves some metals, and turns litmus red.

22

Base

A base is a chemical species that donates electrons or hydroxide ions or that accepts protons.
