Question

Why mg atom gets 2+ charge when it loses two electrons

Answer 1

Answer:

The elements gain there electrons to complete their octet state is called non metals. Non-metals carry negative charge. ... To complete it's octet state it will lose it's 2 electron and form Mg++ . That's why Magnesium carry 2 positive charge when it lose it's electron

Answer 2

Answer:

When mg atom loses two electrons, its balanced state of having an equal number of protons and electrons is disrupted. Since there are two electrons less, the number of protons happens to be greater than the number of electrons, thus making it positively charged. As we know magnesium has atomic no. 12.
