Electrons in an excited state are more likely to enter into chemical reactions.
a. true
b. false

False

Explanation:

The electrons  are excited because:

1.- They posses more energy than the basal form, but this doesn´t mean that they can easily react, remember, the electrons are the outside part of an atom.

2.-  By the time, this electrons are loosing their energy, that mean that they return to the basal form.

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
