The aufbau principle, from the German Aufbauprinzip (building-up principle), also called the aufbau rule, states that in the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels.

How many lone pairs of electrons are on the central carbon atom in a Lewis Structure of CHI3?

Alborosie

There are zero lone pairs of electrons on the central carbon atom in a Lewis Structure of CHI3. The correct option is b.

Explanation:

Lone pair electrons are those valence electrons of an atom which do not take part in bonding or left after the bonds are formed.

CH $I_{3}$

carbon is the central atom in the compound having 4 valence electrons.

Each iodine molecule has 7 valence electrons.

H has 1 valence electron.

from the Lewis structure of CH $I_{3}$ , it is seen that all four valence electrons of the carbon is involved in bonding with 3 atoms of iodine and 1 atom of hydrogen.

Thus when all valence electrons are involved in bonding no lone pair of electron is found in CH $I_{3}$ that means zero lone pairs of electrons.

The octet of the iodine, carbon and hydrogen gets completed to form the compound.

Which statement is true about air temperature and humidity

lapo4ka [179]

Complete Question:

Which statement is true about air temperature and humidity?

Group of answer choices.

a. the air temperature does not affect how much moisture the air can hold

b. hotter air holds less moisture than colder air.

c. hot air and cold air share the same amount of moist.

d. colder air holds less moisture than hotter air.

Answer:

d. colder air holds less moisture than hotter air

Explanation:

Weather can be defined as the atmospheric conditions of a particular area over a short period of time.

The elements of weather include precipitation, wind, temperature, atmospheric pressure, relative humidity, cloud, and wind speed.

Temperature can be defined as a measure of the degree of coldness or hotness of a physical object (body).

On the other hand, humidity refers to the concentration (amount) of water vapor that is present in the air. It is high when there's a lot of water vapor in the air and low when the level of water vapor is small.

Hence, the true statement about air temperature and humidity is that colder air holds less moisture than hotter air because as the air cools, its molecules move closer together while the molecules move farther apart as the air become hot.

Additionally, at constant humidity, relative humidity is inversely proportional to temperature i.e as the temperature decreases, relative humidity increases.
