Question 1

Non polar covalent bond

Answer 1

A non-polar covalent bond is a type of chemical bond that is formed when electrons are shared equally between two atoms. … It further means that there is no separation of charges between the two atoms or both the atoms have similar electronegativity

Question 2

Ionic bond

Answer 2

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

Question 3

Covalent bond

Answer 3

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Question 4

Polar covalent bond

Answer 4

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Question 5

Formula unit

Answer 5

A formula unit in chemistry is the empirical formula of any ionic or covalent network solid compound used as an independent entity for stoichiometric calculations. It is the lowest whole number ratio of ions represented in an ionic compound.

Question 6

Ionic compound

Answer 6

In chemistry, an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions.

Question 7

Formula unit

Answer 7

A formula unit in chemistry is the empirical formula of any ionic or covalent network solid compound used as an independent entity for stoichiometric calculations. It is the lowest whole number ratio of ions represented in an ionic compound.

Question 8

Chemical bond

Answer 8

a connection between two surfaces or objects that have been joined together, especially by means of an adhesive substance, heat, or pressure.

Question 9

Anion

Answer 9

a negatively charged ion, i.e. one that would be attracted to the anode in electrolysis.

Question 10

Structural bond

Answer 10

The union of two or more masonry units so that the combination acts as a single unit and provides the same structural strength as a single unit of the same material.

Question 11

Molecule

Answer 11

a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

Question 12

Polotomic ion

Answer 12

A polyatomic ion is an ion composed of more than one atom. The ammonium ion consists of one nitrogen atom and four hydrogen atoms. Together, they comprise a single ion with a 1+ charge and a formula of NH+4. The carbonate ion consists of one carbon atom and three oxygen atoms and carries an overall charge of 2−

Question 13

Lewis structure

Answer 13

A Lewis Structure is a very simplified representation of the valence shell electrons in a molecule. It is used to show how the electrons are arranged around individual atoms in a molecule. Electrons are shown as “dots” or for bonding electrons as a line between the two atoms.

Question 14

Crystal lattice

Answer 14

the symmetrical three-dimensional arrangement of atoms inside a crystal.

Question 15

Cation

Answer 15

a positively charged ion, i.e. one that would be attracted to the cathode in electrolysis.

Question 16

Oxydation number

Answer 16

The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation of an atom in a chemical compound.
