Chemistry final

2. made up of multiply atoms covalently bonded together with an overall positive or negative charge
7. involves a sharing of electrons atoms will share in order to reach a stable electron configuration; gain
8. the smallest repeating pattern within a crystal; lowest whole number ratio of ions and ionic compounds
9. right side of the stair case and Hydrogen, non-lustrous, brittle, and poor conductors but good insulators, make up covalent bonds
11. chemical formula for an ionic compound arranged in the smallest whole-number ratio
13. touch the stair case and have properties of both metals and nonmetals; semiconductors (high temperature or substances added)
14. (-) are always larger than the neutral atom from which they are made; More electrons repulsion results in less attractive force between the nucleus and energy levels
16. having a net zero charge(a neutral compound)

1. made up of nonmetals only, sharing of electrons, molecule of the same compound are identical and independent of each other, weaker than ionic bonds, lower melting and boiling points made up of a non-metal and a metal, metals lose electrons and non-metals gain electrons
3. a neutral group of atoms joined together by covalent bonds
4. (+) are always smaller than the neutral atom from which they are made; as electrons are lost there is a lose of energy levels(decreased distance results in more attraction)/
5. made up of a single atom
6. the force of attraction that holds metals together
10. is the transfer of electrons; binds oppositely
12. the group of elements that tend to lose electrons; left side of the stair case; lustrous, malleable, ductile, good conductors of heat and electricity
15. transfer of electrons
