Question

A neutral element has 3 electrons, the atomic number of the element is _____.

Answer 1

• The value of the negative charge on an electron is equal to the value of the positive charge on protons.
• This results in the neutral element.
• So it can be said that, for a neutral element, number of electrons=number of protons
• Further, the number of electrons =Number of protons= Atomic number
• Given, that the number of electrons= 3 and using the above relationship, the number of protons= 3 and the atomic number=3

Therefore, a neutral element has 3 electrons, and the atomic number of the element is 3.
