I am not sure what to do for most of them so could you help me?

1.Metals usually react to form cations [T/F]
2.Weak acids and bases are used ti wash clothes[T/F]
3.Acid precipitation results mainly from combustion reactions[T/F]
4.arrangement of elements with similar chemical properties in the periodic table. _____
5.Type of ion that is usaully formed by metal atoms.________
6.group of atoms with a net charge; the atoms are joined by covalent bonds.________
7.type of bond formed when a pair of electrons is shared
8.Phosphorus atom has___valence electrons

Don't you think I did that? We have 60 review questions I have done most of them and only have these left.

As one of these "people", we are more interested in helping you to figure out what to do and then you can do it in subsequent problems. After all, if you DON'T know these (and it is YOU who say they are simple), you may have mucho big problems.
1. Metals usually act as ANIONS (its false)
2. Not sure, but I'd say true (the strong stuff would just eat up the clothes)
3. True, since they problem guys are oxides.
4. are in columns
5 See #1
6 Radicals
7. Covalent
8. Five
9. Sodium. When an anion is formed, the atom LOSES an electron, so you look for the next higher element after neon.

1. true a cation is a positively charged ion and metals lose electrons (thus having a positive charge)
2.i'm pretty sure but oxidizing agents are also used
3.once again pretty sure (coal burning leads to acid rain)
4. in columns
5. cation
6. polyatomic ion
7. covalent
8. 5 electrons
9. Fluoride, oxide, nitride (pick one they are all correct)

Ok

What you do is open a chemistry text book and read your notes from class.

Hope that helps
