Is the bond formed between each pair of atoms pure covalent (a.k.a. nonpolar covalent), polar covalent, or ionic?
swat32

Answer:

So, look up for electronegativity table

There's a continuum for deciding whether the bond is non-polar, polar, or ionic

If electronegativity difference is less than 0.4 it's non-polar

Which of the following statements is/are correct?
vlabodo [156]

Answer:

Option A is correct. Statements b,c and d are true

Explanation:

Step 1: Data given

Proton = a subatomic particle with a positive electric charge of +1 and a mass slightly less than that of a neutron.

Neutron = a subatomic particle of about the same mass as a proton but without an electric charge

electron = a subatomic particle whose electric charge is negative one elementary charge.

The mass of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom

Step 2: Statements

(a) Protons have a charge of -1.

This is false. Protons have a charge of +1

(b) Neutrons have no charge.

 This is true

(c) An electron has negligible mass compared to the mass of a neutron

 This is true

(d)Number of proton equals to number of electrons on a stable atom

This is true. A stable atom has a charge of 0. this means the same amount of protons and electrons

Option A is correct. Statements b,c and d are true
