Question

Answer

Answer

The nucleus of a tritium atom, 3H, contains two neutrons and one proton.

Explanation:
- Tritium is a radioactive isotope of hydrogen. It has a mass number of 3 and an atomic number of 1, which means it has one proton in its nucleus.
- The mass number of an atom is the sum of its protons and neutrons. Therefore, the nucleus of tritium must contain two more particles to make up its mass number of 3.
- Since the charge of the nucleus is determined by the number of protons it contains, tritium's nucleus must have one proton.
- Therefore, the remaining two particles in tritium's nucleus must be neutrons, making the answer option D - two neutrons and one proton.

Answer

Tritium is isobar so the protons will remain same which is 1 and the left of the mass is of 2 neutrons

Answer

Mass Number =Sum of Proton and Neutron
:.Therefore, In Tritium Mass Number is equal to 3 i,e One proton And Two Neutron

Answer

No. of Proton = atomic number and number of neutron =atomic mass - atomic number...

Answer

D hoga

Answer

There are two neutrons and one proton in the tritium of Hydrogen. This is because the atomic no. of element depends upon the no. of protons present in it. Thus the atomic no. of Hydrogen is One so it has only one proton and then in tritium of Hydrogen two neutrons will left

Answer

Tritium's mass no. is 3. And as we know atomic no. of hydrogen is 1 .so, no. of neutrons =mass no. - no. of protons, 3-1=2 .no. of neutrons =2 .thus,tritium has 2 neutrons and 1 proton.

Answer

D is right

Answer

Since tritium atom atomic mass =3 and atomic number=1 As we know that,Atomic number=no of protons no of protons must be only 1and addition of protons and neutrons gives us the atomic mass of the atom(1+n=3) therefore.No of neutrons =2

Answer

Atomic number of tritium is the same as that of hydrogen, i.e. 1. (Note that atomic number is the number of protons.) It is the atomic mass number that is different. For tritium, atomic mass= 3. Atomic mass= no. of protons + no. of neutonsWe know that the atomic number remains same in isotopes, i.e. 1 in thia case.For tritium,3= 1+ no. of neutronsno. of neutrons= 2
