Question

calculate the number of protons neutrons and electrons in two moles of mg2+ ions​

Answer 1

Explanation:

24 gm of Magnesium contains=N

A

atoms. Where N

A

= 6.023 × 10

23

48 gm of Mg contains =2N

A

atoms.

1 atom of Mg contains 12 electrons

Mg

2+

ion will contain (12–2)=10 electrons

2N

A

Mg

2+

ions will contain

=10×2N

A

electrons

=10×2×6.023×10

23

=20N
