Can you fill-out the characteristics of Magnesium ion?
Atomic Number: ?
Mass Number: 25
No. of Electrons: ?
Electron Config: 2,8
Ion of Charge: ?
No. of Protons: ?
No. of Neutrons: ?
Also, can you explain how you found them.

ok given the mass number
Mass number = number of protons + neutrons (( together ))
Since it's Magnesium , the Atomic number is 12 (( from periodic table ))
and Atomic number = number of protons = 12 Protons
so number of Neutrons = mass number - atomic number = 25 - 12 = 13 Neutrons
since Electron config is 2 , 8
this means that the number of electrons is 10
knowing that protons = 12
then the Magnesium has 2 more protons than electrons
this means the charge of ion is 2+
Mg2+ (( Symbol of Magnesium Ion ))
