Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride
The gases have no definite shape, low density, and are highly compressible while the liquids only have a definite volume but no definite shape.
<h3>What is a Matter?</h3>
Any substance which has mass and occupies space is called matter. Commonly, there are three states of matter that are:
- Solid - Solids have a rigid shape, definite volume, and high density.
- Liquid - Liquids have definite volume but no definite shape. They take the shape of the container in which they are placed.
- Gas - Gases have neither definite shape nor definite volume and have low density. They completely occupy the container in which they are placed.
There are other two states of matter that are Plasma and man-made Bose-Einstein condensates. They are not so common.
Plasma is commonly found in the universe. Stars are the superheated balls of the plasma.
Thus, gases have no definite shape, low density, and are highly compressible. On the other hand, the liquids only have a definite volume but no definite shape.

Solution
Given mass of FeBr2 = 85.5 g
Molar mass of FeBr2 = 215.65
No. of Moles of FeBr2 = Given Mass / Molar mass = 85.5 / 215.65
No. of Moles = 0.3964
Given Volume is 450 mL i.e. 0.450 L
Now Concentration = 0.3964/0.450
Hence Concentration = 0.881 mol/L
Answer:
The answer to your question is below
Explanation:
Ionic bond is a kind of bond in which a metal attaches to a nonmetal. Also we know that a molecule has ionic bonding if the electronegativity is higher than 1.7.
Kind of elements Difference of electronegativity Bond
a) MgO Metal - Nonmetal 3.44 - 1.31 = 2.13 Ionic
b) SrCl₂ Metal -Nonmetal 3.16 - 0.95 = 2.21 Ionic
c) O₃ Nonmetal- Nonmetal 3.44 - 3.44 = 0 Covalent
d) CH₄O Nonmetal-Nonmetal 3.44 - 2.55 = 0.89 Covalent
Carbon, Hydrogen and oxygen are nonmetals
2) Silver coins can conduct electricity.
