X Y Z

Protons 3 6 7

Neutrons 4 6 7

Calculate (i) Atomic number(ii) mass number.Of X, Y, and Z.​

Answer 1

Answer:

Chemistry is a branch of natural science that deals principally with the properties of substances, the changes they undergo, and the natural laws that describe these changes.

Answer 2

Atomic numbers of X, Y and Z are 3,6 and 7.

The mass number of X, Y and Z are 7,12,14.

• The atomic number of an atom is the number of protons present in the atom.
• Hence the atomic numbers X, Y and Z are 3,6 and 7.
• Again, the mass number of an atom is the sum of the number of protons and the number of neutrons in that atom.
• Hence the mass number of X, Y and Z are 3+4=7, 6+6=12 and 7+7=14.
