Answer: Electronegativity increases across a period.

Explanation:

Electronegativity is defined as ability of an atom to attract shared pair of electrons in a bond toward itself.

Electronegativity increases across the period because when we move across the period from left to right numbers of protons and electrons are increased. By increase in number of protons ,nuclear charge also increases due to which electrons present in an atom are strongly attracted towards the nucleus. And due to presence of strong nuclear charge shared pair of electrons in a bond are also attracted towards nucleus of an electronegative atom.

I believe the answer would be A. Electronegativity increases across a period.

why don't electrons, which are attracted to the protons in the nucleus, simply fall into the nucleus?

Murljashka [212]

Answer:

electrons are fermions, they can only access an energy level if it has not already been occupied by another electron. Thanks to this principle, there is a minimum energy level within the atom and it is not possible for an electron to collapse to the nucleus because it cannot exceed this} threshold.

10. Which would make the best aquifer?

Levart [38]

c. sandstone in the zone of saturation

Explanation:

The best aquifer of all is a sandstone in the zone of saturation. An aquifer is a porous and permeable formation where groundwater can accumulate.

To be a good aquifer, a rock or soil must be porous and permeable.
Porosity is the amount of void spaces present in a rock.
Permeability is the inter-connectivity of the pore spaces.

The zone of saturation is the zone below the water table where water is always present underground.

Sandstones have high porosity and permeability.
They are good aquifers when found at the zone of saturation.

Hydrochloric Acid would best be described as a:

Sunny_sXe [5.5K]

Hydrochloric Acid would best be described as an Arrhenius and BrØnsted-Lowrey acid.

<h3>Is Hydrochloric Acid considered a Brønsted-Lowry acid?</h3>

Hydrochloric Acid HCl(g) is the proton donor and therefore a Brønsted-Lowry acid.

<h3>Is Hydrochloric Acid considered an Arrhenius acid?</h3>

According to Arrhenius theory, hydrochloric acid is an acid which gives hydrogen ions in water but according to Bronsted-Lowry theory, hydrochloric acid is an acid because it donates a proton to the water molecule.

<h3>Is Hydrochloric Acid considered a Lewis acid?</h3>

Hydrochloric acid (HCl) cannot be classified as a Lewis acid since it cannot accept an electron pair.

Thus, hydrochloric Acid would best be described as an Arrhenius and BrØnsted-Lowrey acid.
