Question

please give ans plese....

Answer 1

Isotopes are atoms that have the same number of protons and electrons but different numbers of neutrons and therefore have different physical properties.
[technical]
...tritium, a radioactive isotope of hydrogen.

Similarity between two pair of isotopes is black they have the same chemical properties but the difference between two isotope is that their physical property differ.
No. of electron = No. of protons = Atomic No.
No. Of neutron = Mass no. - Atomic no.
in the first case number of neutrons is equal to 10 in the second case that is chlorine 17 37.. number of neutron is equal to 10..

Answer 2

a.))One of two or more forms of a chemical element that have different physical characteristics but the same chemical characteristics are called as Isotopes.
b.))Diamond and graphite are the Isotopes of carbon .
Diamond is one of the hardest substance on the planet and is a bad conductor of heat and electricity.
Graphite is brittle and is a good conductor of heat and electricity due to presence of motor electrons.
c.))
1.) No. of electrons =No. of protons = 15
No. of neutrons =35-15 =20

.
2.) No. of electrons=No. of protons =17
No. of neutrons =37-17 =20.
.
.
Here's your answer.
Hope it will help you.
