A force of attraction that holds atom together 
<span>When atoms react they form a chemical bond which is defined as a force of attraction that holds atom together. A force of attraction is defined as a kind of force that draws two or more objects together regardless of distance. There are two major categories of forces of attraction, one is intramolecular and intermolecular. Intramolecular forces is the presence of forces in atoms internally. While intermolecular is the force by which the force that is existent in two or more elements. </span>

With what elements does nitrogen form ionic bonds?
Andrew [12]

Answer:

Group 1 and 2 elements

Explanation:

Nitrogen, a non-metal will form ionic bonds with most group 1 and group 2 metals on the periodic table.

How does ionic bonds form?

  • They are bonds formed between a highly electronegative specie and one with very low electronegativity.
  • As such, ionic bonds forms between metals and non-metals
  • In this bond type, the metal due to its electropositive nature will transfer electrons to the non-metals for it to gain.
  • The non-metals becomes negatively charged as the metal is positively charged.
  • The electrostatic attraction between the two specie leads to the formation of ionic bonds.

Most metals in group 1 and 2 fits in this description. Some of them are calcium, magnesium, lithium, Barium e.t.c.

It mostly favors group 2 metals.

Add groups to complete polyvinyl alcohol, formed by the polymerization of the following monomer. If a carbon atom contains only
e-lub [12.9K]

Answer:

The resulting structure is:

R-CH-CH2 (OH)-CH-CH2(OH)-CH-CH2(OH)-CH-...

Explanation:

It can be said that vinyl alcohol cannot be polymerized by addition polymerization, since a very unstable radical would be formed, which is not possible. Generally, it is formed by polymerization and subsequent hydrolysis of the vinyl polyacetate. According to the exercise, the structure that results with its four units can be seen that the hydroxyl groups are found in the methylene carbons
