Question

A central purple circle labeled N a has 3 concentric rings around it. The inner ring has 2 small green spheres. The middle ring has 8 small green spheres. The outer ring has 1 small green sphere. Does this atom satisfy the octet rule? Why or why not?

Answer 1

Answer:

This atom doesn’t satisfy octet rule

Explanation:

To satisfy octet rule the outermost shell should have 8 electrons. This is called octet electronic configuration which makes the atom stable. When participating in chemical reactions atoms tend to lose or gain electrons or share electrons like in a covalent bond all to achieve the octet configuration.

In this atom there are three shells and 11 electrons in total. Maximum number of electrons that can be present in the first shell is two and in this atom the first shell contains that maximum electrons. The second can contain maximum 8 electrons. In this atom the second shell is fully filled with 8 electrons.

For octet rule to be satisfied the outermost shell or the valence shell should contain 8 electrons. But in this atom the outermost shell has 1 electron. This means that the atom doesn’t satisfy octet rule. In order to obtain the octet configuration it should lose 1 electron.

Answer 2

Answer:

Explanation:

Sample Response: No, it does not, because the octet rule says that an atom needs to have eight electrons in its valence shell to be stable. The exceptions are hydrogen and helium, which need only two electrons. This atom has only one electron.
