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.

.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
