How many electron shells does the beryllium atom have?

Answer 1

Two energy shells.

Made up as

1s2, 2s2

Shells 1 & 2 each have only 's' orbital and each orbital has only two electrons in it. The outer shell '2' is more energetic. The electrons are paired and spin in opposite directions to each other.

Answer 2

The beryllium atom has 2 electron shells. The first shell, closest to the nucleus, can hold up to 2 electrons, while the second shell can hold up to 8 electrons. Beryllium has 4 electrons, filling both of its electron shells.

Answer 3

Beryllium has two electron shells: 1s2.2s2

Answer 4

The valence of beryllium is two. Beryllium has the electronic configuration 1s2,2s2 so the valence is 2 for Be.

Answer 5

Two shells, the innermost having two out of two electrons and the second shell is incomplete having only two out of eight electrons.

Answer 6

Beryllium's electron configuration is 2s^2. It has two shells and has two electrons occupying the "s" orbital.

Answer 7

2
Electron configuration of beryllium: 1s2.2s2

Answer 8

Beryllium has two electron shells, each containing two electrons.

Answer 9

This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.

Answer 10

Beryllium has 2 electron shells.
