Chemical

1. Atoms -The smallest component of an element having the chemical properties of the element.

   • Molecule of element- Same type of atom chemically combined

2. Molecules - Group of two or more atoms chemically combined together.

   • Molecules of compound-two or more elements chemically combined

3. Electrically Neutral - Proton has the same opposite charge as electron

4. "The nucleus of an atom is positively charged"- The nucleus of an atom consist of protons which are positively charged and neutrons which have no change.Hence, the charge of nucleaus of an atom is positively charged.

5. Isotopes- Atoms of the same number of protons but different number of neutrons.

6. Ions- Charged particles with the same nuber of protons

7. Lattice Patern- Repeating pattern of (element) and (element)
