A sound at 160 decibels is considered loud whereas a sound at 20 decibels is considered soft.

The intensity or volume of sound is measured in unit called decibel or dB. For normal conversation, the intensity of sound is 60 decibel. Loud noise for very long time can damage the ears and very loud sound can instantly harm the ear, causing hearing problems. Sound till the range of 70 decibel is considered safe for hearing. The intensity of sound at 120 decibel causes immediate hearing issues.

Sources of loud noise include crackers, Very high volume of television, radio or earphones. The loud sound can cause damage to cells and membranes in the ears. This damage is irreversible and hence leads to permanent hearing issues.

The statement that "the lowest energy configuration for an atom is the one having the maximum number of unpaired electrons allow
LUCKY_DIMON [66]

Answer:

Hund's rule

Explanation:

Hund's rule is defined as the rule whose first rule in the chemistry says that, for a given electronic configuration, the term which posses lowest energy has maximum multiplicity. The multiplicity is defined as the tem 2S+1, where S is the total spin angular momentum.

Therefore, the term which has lowest energy that term posses maximum number of S.

Hund's rule of maximum multiplicity: Electron present in same energy orbitals firstly they completed half orbit than start pairing.

Therefore, the energy of lowest configuration for an atom is the one having the maximum number of unpaired electron which is allowed by the Pauli principle in a particular set of degenerate orbit is called Hund's rule.
