Question

Explain with examples (1) Atomic number, (ii) Mass number, 8. (ii) Isotopes and iv) Isobars. Give any two uses of isotopes.​

Answer 1

Atomic number: The atomic number is the total number of protons present in the atom. For example, the atomic number of Mg is 12. It contains 12 protons and 12 electrons. ... For example, the atomic number of Lithium is 4 which is equal to the number of protons, the number of neutrons of magnesium is 4

Answer 2

Answer:

1) the atomic number is total number of protons present in the atom.

for example :- the atomic number of Mg is 12 . it contain 12 protons and 12 electrons.

2) mass number - it is the sum of the number of neutrons and the number of protons.

for example :- the atomic number of magnesium is 12 which is equal to the number of protons, the number of neutrons of magnesium is 12 .

the mass number is equal to 24(12+12) .

3) isotopes are the elements having same atomic number but different mass number.

for example :- 6 C^12 , 6 C^12 , 6 C^14 are the three isotopes of carbon.

4) they are elements having the same mass number but different atomic number.

for example:- 18 Ar^40 , 19 K^40 are Isobars having the same atomic mass but different atomic number.

5) nuclear weapons and nuclear power require large quantities of isotopes of uranium.

aana isotope odd cobalt is used in the treatment of cancer.
