Question

The electron configuration of an element is shown below.

1s22s22p5

Name the group this element belongs to in the periodic table and explain your answer.

Based on the electron configuration, explain how many electrons it is likely to receive from the atom of another element during the formation of a bond.

Answer 1

what do you think it is

Answer 2

Any ideas?

Answer 3

What element would 1s2 2s2 2p5 be?

Here are some example of other elements and their electron configuration

Answer 4

This element belongs to the halogen group and the element is also fluorine.

Answer 5

@tranquility

Answer 6

You found it by looking at the periodic table

Answer 7

Because fluorine is the only element with that electron configuration

Answer 8

The first image I attached clearly tells you which orbital the last electron is in.

If you don't know the s, p, d, f blocks then this should help

Answer 9

Yes

Answer 10

Ok so how does 1s22s22p5 belong to the halogen group

Answer 11

As for the second half of your question:
`Based on the electron configuration, explain how many electrons it is likely to receive from the atom of another element during the formation of a bond.`

How many electrons does it need for it to have the same electron configuration of a noble gas?

Remember, halogens are very reactive.
Think of HI, HCl, HF

How many electrons is the hydrogen sharing with these halogens?

Answer 12

1?

Answer 13

Yes

Answer 14

Ok thank you so much <3!

Answer 15

You're welcome!
