What is electron shielding?

2 answers:

5 0

Electrons in an atom can shield each other from the pull of the nucleus. This effect, called the shielding effect, describes the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell. ... The more shielding that occurs, the further the valence shell can spread out.

Answer:

C.) 35

Explanation:

The mass is made up of the total protons and neutrons in an atom. Protons and neutrons both have a mass of 1 amu. Electrons are not included in this measurement because they have an insignificant mass (practically 0).

(17 protons x 1 amu) + (18 neutrons x 1 amu) = 35 amu

Therefore, if an atom contains 17 protons and 18 neutrons, the mass should be 35 amu.
