500

How many energy levels and valence electrons does an element have if it is in Group 17 and Period 2?

7 valence electrons and 2 levels

500

As you move down a group on the periodic table, the number of valence electrons of the elements tends to _________.

stay the same.

500

How many valence electrons do members of the Alkaline Earth Metals have? 

2 (since they are in Group 2) 

500
These elements are poor conductors of heat and electricity
non-metals
500
What is the difference between ionic and covalent compounds?
Ionic compounds form when atoms lend or borrow electrons. Covalent compounds form when atoms share electrons by overlapping valence levels. OR Ionic compounds form between a metal and non-metal Covalent form between two or more non-metals.
