A molecular orbital that decreases the electron density between two nuclei is said to be ____.
nikklg [1K]

A molecular orbital that decreases the electron density between two nuclei is said to be <u>antibonding.</u>

The bonding orbital, which would be more stable and encourages the bonding of the two H atoms into H_{2}, is the orbital that is located in a less energetic state than just the electron shells of the separate atoms. The antibonding orbital, which has higher energy but is less stable, resists bonding when it is occupied.

An asterisk (sigma*) is placed next to the corresponding kind of molecular orbital to indicate an antibonding orbital. The antibonding orbital known as * would be connected to sigma orbitals, as well as antibonding pi orbitals are known as \pi* orbitals.

Therefore,  molecular orbital that decreases the electron density between two nuclei is said to be <u>antibonding.</u>

<u></u>

Hence, the correct answer will be option (b)

How does the periodic table help in predicting the formula of a stable ionic compound?
marshall27 [118]
A. This is a FALSE statement because Metals in Group 1 form cations with a +1 charge and not -1. 

B. This is a TRUE statement. 

C. This is a FALSE statement because metals do not form anions i.e. negatively charged ions but form cations i.e. positively charged ions. 

D. This is a FALSE statement because metals do not form anions i.e. negatively charged ions but form cations i.e. positively charged ions.

The mass number for an atom is numerically equal to which quantity
Misha Larkins [42]

Answer:

The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in an atom is its mass number minus its atomic number.

Explanation:

protons

The mass number of an atom is its total number of protons and neutrons. Atoms of different elements usually have different mass numbers , but they can be the same. For example, the mass number of argon atoms and calcium atoms can both be 40.
