Question

We say that ______ electrons penetrate towards the nucleus better than _______ electrons.

a) Valence electrons, core electrons
b) Core electrons, valence electrons
c) Electrons with positive charge, electrons with negative charge
d) Protons, neutrons

Answer 1

Valence electrons penetrate towards the nucleus better than core electrons.

Step-by-step explanation:

Valence electrons penetrate towards the nucleus better than core electrons.

Valence electrons are the outermost electrons in an atom and are involved in chemical bonding. They have higher energy levels and are more likely to interact with the positively charged nucleus.

On the other hand, core electrons are the inner electrons, closer to the nucleus. They have lower energy levels and are less likely to interact with the nucleus.
