What is the mass number of a carbon atom that contains 6 protons 8 neutrons 6 electrons?

1 answer:

7 0

Mass no. = Protons + Neutrons
Mass no.= 6 + 8
= 14

If you look at the periodic table, you will see that the carbon atom has a mass number of 12. But if you compare with this carbon, it is 14. This is because this carbon atom is an isotope. The isotope is called carbon-14.

1. Mg + CuSO4 —> MgSO4 + Cu

=> Single displacement reaction

2. 2HCI + Mg(OH)2 —> MgCI2 + H2O

=> Acid - base reaction

3.AgNO3 + NaCI —> AgCI + NaNO3

=> Double displacement reaction
