Why does nuclear charge increase as you go left to right across a period

1 answer:

7 0

The atomic number increases moving left to right across a period and subsequently so does the effective nuclear charge. Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases.

If I have 13 g of C, how many moles of C do I have?

Triss [41]

C = Carbon

If you look in a periodic table and see the mass number for carbon. Its estimated around 12.

I believe it's between 1-2 moles.

All you have to do is 13/12 which will give yoy the estimated answer which is around 1.08 mole.
