Write a covalent compound formed by nitrogen and oxygen. what is its Lewis structure​
iragen [17]

Answer:

Two covalent bonds form between the two oxygen atoms because oxygen requires two shared electrons to fill its outermost shell. Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell.

An atom or ion has 41 neutrons, 36 protons, and 36 electrons. Identify the element symbol, and determine the mass number
igor_vitrenko [27]

Answer:

Element symbol: Kr.

Mass number: 77.

Charge : 0.

Explanation:

Hello,

In this case, since such substance has the same amount of protons and electrons we can infer it is an atom whose number of neutrons is defined by considering its atomic mass or mass number and atomic number which is actually equal to the number of protons and electrons (36):

neutrons=atomic\ mass - atomic\ number

In such a way, solving for the atomic mass we obtain:

atomic\ mass=neutrons+ atomic\ number\\\\atomic\ mass=41+36=77

It means that the element is krypton (Kr) as it has 36 electrons and protons so its charge is 0.

Best regards.
