Question

Calculate the number of electrons protons and neutrons of the elements whose mass number and atomic number are 35&17 respectively

Answer 1

Question :

Calculate the number of electrons protons and neutrons of the elements whose mass number and atomic number are 35&17 respectively

To Find :

• The number of electrons in the given element

• The number of protons in the given element

• The number of neutrons in the given element

Solution :

The element with atomic mass and atomic number 35 & 17 respectively is chlorine.

Number of Electrons :

• The number of electrons in any given element is its atomic number.

• The atomic number of chlorine is 17.

• So chlorine has 17 electrons.

Number of Protons :

• The number of protons in any given element is its atomic number.

• The atomic number of chlorine is 17.

• So chlorine has 17 electrons.

Number of Neutrons:

• The number of neutrons in any given element is the difference of atomic number from the atomic mass.

• The atomic number of chlorine is 17. The atomic mass of chlorine is 35.

• Atomic Mass - Atomic Number = Neutrons ⇒ 35 - 17 = 18

• So chlorine has 18 electrons.

Answer :

Chlorine has 17 electrons , 17 protons  & 18 neutrons

Answer 2

Answer: number of electrons is 17,

Number of proton is 17. And number of nutron is 18

Explanation: because it's atomic number is 17 and number of electrons and protons are always same in neutral atom so number of electrons and protons are 17 and mass number is the sum of number of proton and nutron so here number of nutron is the difference of mass number and protons then we get 18 as a nutron
