Which of the following is a property of ionic compounds? Solids may be soft, waxy, or flexible. OAt ambient temperature, they may be a solid, liquid, or gas. They have a relatively low melting point. They conduct electricity when dissolved in water.

What element am I?  a) In my natural state I am a diatomic element. When I form an ionic compound, I am a negative ion and have one more electron than my number of protons. In my group and my period, I am the smallest element. b) My atomic number is 29 and I readily form +1 and +2 cations.  c) Give the chemical formulas for the two ionic compounds that can be formed by the element in part a and the element in part b.
