Compared to a phosphorus atom, a P3- ion has

Answers

Answer 1

Answer:

Answer:

Three more electrons

Explanation:

Compared to a phosphorous atom (P) the P3- ion has gained 3 electrons resulting in the trivalent negative charge. P3- is a reduced state of P and to name some properties:

It has a bigger atomic radius due to the extra electrons and the weaker attraction the protons have to them.
It can react as a base (taking electrons)

Answer 2

Answer: Compared to a phosphorus atom, a P3- ion has more electrons and a larger radius. With a negative charge means there are more electron than protons, this increases the radius because positive charge is trying to hold a larger negative charge. Hope this helps

Which statement describes an alternate theory of acids and bases?(1) Acids and bases are both H+ acceptors.
(2) Acids and bases are both H+ donors.
(3) Acids are H+ acceptors, and bases are H+ donors.
(4) Acids are H+ donors, and bases are H+ acceptors.

Answers

Answer: Option (4) is the correct answer.

Explanation:

According to Bronsted and Lowry, acids are the species which can donate hydrogen or $H^(+)$ ions.

Whereas bases are the species which can accept hydrogen or $H^(+)$ ions.

Thus, we can conclude that the statement acids are $H^(+)$ donors, and bases are $H^(+)$ acceptors describes an alternate theory of acids and bases.

The answer is (4) Acids are H+ donors, and bases are H+ acceptors. This constitutes the Bronsted-Lowry theory of acids and bases.

The first shell can hold a maximum of two electrons. How does this explain the valence of hydrogen?

Answers

The hydrogen atom has only one electron which is present in the first shell.

We know that first shell can hold a maximum of two electrons so due to incomplete valance shell hydrogen atom is reactive and make covalent bond with other reactive atoms. This bonding will complete its valance shell and finish its reactive nature. In the second shell and other shells can hold 8 electrons so we can conclude that hydrogen has one valance electron.

Generally, which of the three families of elements (metals, nonmetals, or inert gases) has the least tendency to form ionic bonds?

Answers

Answer:

Inert gases

Explanation:

Inert elements have a stable electron configuration meaning their shells/orbitals are full with their requisite number of electrons. Therefore, gaining or losing an electron would take high ionization energy. Therefore they are less likely to be involved in chemical reaction unless a high amount of energy is used. An example of an inert gas is Helium.
