Question

11.Which of the following statements about the valence electrons is false?Select one:a. Valence electrons are involved in bonding.b. Valence electrons are found in the outermost energy level.c. Number of valence electrons determines whether atom forms a covalent or ionic bond.d. Valence electrons are found in the nucleus.

Answer 1

d. Valence electrons are found in the nucleus.

Step-by-step explanation:

Valence electrons are the electrons in the outermost shell, or energy level, of an atom.

The other 3 statements are correct.

Answer 2

`D`

Step-by-step explanation:

Here, we want to select the wrong option about valence electrons

Let us consider the given options one after the other:

a) This is correct. They are the means through which atoms combine to give molecules through chemical bonding

b) This is correct. They reside in the farthest energy level from the nucleus

c) This is correct. With a few valence electrons, such as 1, 2 and 3: the type of bonds formed by the atom would be electrovalent or ionic. While with higher number of valence electrons, the atom is likely to enter into covalent bonding

d) This is incorrect. Valence electrons are not found in the nucleus
