Magnesium has 12 protons. what charge do you expect it to have when it ionizes? why?

This element has +2 charge on it.

Explanation:

An ion is formed when an atom looses or gains electrons.

Magnesium is the 12th element of the periodic table having electronic configuration of

This element will loose 2 electrons to attain stable electronic configuration and leads to the formation of a cation having formula

Hence, this element has +2 charge on it.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
