Nucleus of tritium
a. 2 and 0
b. 1 and 1
c. 2 and 1
d. 2 and 2

C = 2 and 1

Explanation:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other

The nucleus of tritium contain two neutrons and one protons.

Tritium is the isotopes of hydrogen whit atomic mass 3 amu. The other two isotopes of hydrogen are protium and deuterium.

The atomic mass of deuterium is two amu having one proton and one neutron and atomic mass of protium is one having one proton and zero neutron.

All isotopes have same atomic number one.

Isotope:

The isotope of an element have same number of protons but different number of neutrons thus having same atomic number and different atomic mass.

.

the right answer is c i just did the question.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
