Question

How many Protons will an atom have with Atomic number 17 and Mass number 35 have?

Answer 1

An atom of chlorine-35 contains 18 neutrons (17 protons + 18 neutrons = 35 particles in the nucleus) while an atom of chlorine-37 contains 20 neutrons (17 protons + 20 neutrons = 37 particles in the nucleus). Adding or removing a neutron from an atom's nucleus creates isotopes of a particular element.

Answer 2

Answer :-

• Number of protons of the atom is 17.

Explanation :-

To Find :-

• The proton of an atom

Solution :-

Given that,

• Atomic number of an atom = 17
• Mass number of an atom = 35

According the question,

• Number of protons the atom has.

As we know that,

Atomic number = Number of proton = Number of electrons,

Therefore,

➞ 17 = Number of protons

➞ Number of protons = 17

Hence,

• Number of protons of the atom is 17.

Some more information related to atomic number and mass number :-

• Atomic number = Number of protons = Number of electrons

• Mass number = Number of protons + Number of neutrons

• Number of neutrons = Mass number - Number of protons.
