Answer:
B
Explanation:
If you remeber a balloon in hot air, it pops. This is because the molecules are moving too fast and need more space to move, thus popping the balloon. If you put a balloon in cold air, then it shrinks, the molecules not moving fast enough and don't need as much space.
<span>Their charges would be +2. When Group 2 elements lose two electrons they form positively charged ions (+2) ions. Magnesium, Calcium, Beryllium Strontium and Barium, lose their electron form positively charged Mg2+, Ca2+, Ba2+, Be2+ Sr2+ ions. These elements lose their electrons to obtain a noble gas electronic configuration.</span>
