What will be the charge of magnesium atom after donating electrons to attain a stable electronic configuration? (Explain)
Answers
Answer:
+2 is the answer
Explanation:
atomic number of magnesium is 12.
the electronic configuration is:
- K=2
- L=8
- M=18
- N=32
we know that atoms are neutral because thenumber of electron is equal to the number of proton. here atomic number is nothing but the number of protons.so 12 is the number of protons and electrons in the magnesium atom.
so,the electronic configuration of magnesium is:
2+8+2=12 (atomic number)
2,8,2 is the electronic configuration
here magnesium has extra 2 electrons so he donates that 2 electrons to make itself stable. when electron(-) is donated that means negative charge is given out so the magnesium atom gets converted to magnesium ion with a positive charge.the number of electron donated will the the positive charge that means the charge of magnesium ion is +2.
when an atom looses or gains electrons then a change in charge takes place that converts aan atom to an ion.
