What is the net ion charge of beryllium?

Explanation:

Beryllium is a group 2 element and its atomic number is 4. Electronic configuration of beryllium is .

Since, a beryllium contains two valence electrons so, in order to attain stability it will readily lose its 2 valence electrons.

Therefore, a beryllium atom upon losing two valence electrons will acquire a +2 charge.

Thus, we can conclude that the net ion charge of Beryllium is +2.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

i think its 100.

hope this !
