Answer: By losing its two outermost electron

Explanation:

Calcium is a element that belongs to group 2 in the periodic table. It has an atomic number of 20, and an electronic configuration of 2, 8, 8, 2.

Hence, to form an octet structure, it gives off its two electrons as shown below:

How would you characterize the style of parenting under which you were raised? Was the same style used by both of your parents?
krek1111 [17]

Answer:

Explanation:

I have been raised under an autthoritative parenting style, and my parents were both raised under an authoritarian style (it was more evident in my mother, because my father's mum died when he was 13). I think it was authoritative because they didn't let me do whatever I wanted, but they also didn't keep so much control on me, so I had certain level of freedom, as long as I didn't break anything xD
