Answer 1

Answer:

are called free electrons

Answer 2

Answer:

The neutral species with unpaired electrons are called Free radicals.

Explanation:

A free radical is a molecule or ion with an odd number of electrons or an unpaired electron (doublet state because the electron has 2 magnetic quantum numbers i.e. ± 1/2 ).

• Free radicals are a deviation as they disobey the octet rule which requires eight electrons (exception is for Hydrogen with 2 e⁻) around each atom

• Homolytic cleavage results in free radicals. There exists a variation in reactivity and stability of free radicals.

• As free radicals possess odd or unpaired electrons; that means not paired with another electron of opposite spin. So the net charge is zero as it is electrically neutral in carrying the same number of electrons and protons.

Hence the neutral species with unpaired electrons are called -

Free radicals.
