Answer:

B

Explanation:

So when you are calculating relative abundance you are actually calculating the atomic mass on the periodic table. So you are given the two isotopes of Carbon C-12 and C-13. Now you know that the atomic mass of C is 12.01 so you have to see that you have a lot more C-12 because the atomic mass is close to 12. Now you can calculate them out like this (0.99 x 12.0) +(.01 x 13.00)=12.01.

Why is true about electron dot diagrams
vazorg [7]

Answer: The correct answer is the option: B. An element with eight valence electrons is chemically unstable.

Explanation:

Hello! Let's solve this!

We will analyze each of the options:

A. The group number of the element provides a clue to the number of valence electrons: it is correct, since it provides the number of valence electrons.

B. An element with eight valence electrons is chemically unstable: this is not correct, since elements with eight electrons in the valence shell cannot react because they already have the last complete shell. Therefore, they are chemically stable.

C. The points must be placed one at a time on each side of the chemical symbol: it is correct, because that is the way to make the point diagram.

D. An atom is chemically stable if all the points are paired: this is correct since this verifies that the point diagram has been done well.

We conclude that the correct answer is the option: B. An element with eight valence electrons is chemically unstable.

Hope this helps.....  Stay safe and have a Merry Christmas!!!!!!!!! :D
