Question

What does the number at the top of the square above tell you about carbon?

Carbon has 6 isotopes.
A carbon atom has 6 protons in its outermost energy level.
Carbon has an average atomic mass of 6.
A carbon nucleus has 6 protons.

Answer 1

A carbon nucleus has 6 protons.

Step-by-step explanation:

The Atomic number tells u how many protons are in the nucleus of an atom

Hope this helps!

Answer 2

A carbon nucleus has 6 protons.

Step-by-step explanation:

As known that the neutral carbon has atomic mass of 14 which has the configuration of 6 protons 6 electrons and 8 neutrons. There are two alternative form of carbon which are said isotopes of carbon.

And as known that the configuration of the protons in the carbon is like that they are all lies in the interior of the nucleus and electrons are lies in the outermost shell of the atom.

So, the number which lies at the top of the square of carbon tells that its nucleus contains 6 protons.
