Science

Question 1

He was an American physical chemist whose concept of electron pairs led to modern theories of chemical bonding.

Answer 1

Gilbert lewis

Question 2

A system uses symbol of an element and one dot represent each

Answer 2

valence electron.

Question 3

During the chemical bonding, an atoms need to attain eight electron in its outermost energy to become stable

Answer 3

(Octet Rule).

Question 4

refers tothe tendency of atoms to prefer to have eight electrons in the valence shell.

Answer 4

octet rule

Question 5

Atoms follow the octet rule by either

Answer 5

donating/accepting electrons or by sharing electrons.

Question 6

: refers to the process where an atom, ion, or molecule gains an additional electron.

Answer 6

Accepting Electrons

Question 7

: refers to the process where an atom, ion, or molecule loses an electron, which is typically part of oxidation reactions.

Answer 7

Donating Electron

Question 8

: share pairs of electrons to achieve a more stable electron configuration, typically to complete their outer (valence) electron shell, achieving a noble gas-like configuration.

Answer 8

Sharing Electrons

Question 9

Answer 13

Gilbert Lewis

Question 14

A system uses symbol of an element and one dot represent each

Answer 14

Valence Electron

Question 15

This rule dictates that atoms are most stable when their valence shells are filled with eight electrons

Answer 15

Octet Rule

Question 16

Question 23

is responsible for the formation of many substances around us.

Answer 23

Bonding

Question 24

. The ability to accept one or more electrons is another property that greatly influences the chemical behavior of atoms. This is called

Answer 24

electron affinity.

Question 25

is the ability of an atom to attract electrons within molecules (bonded atoms) rather than a free electron.

Answer 25

Electronegativity

Question 26

, also called as electrovalent bond, is a type of bond that involves the complete transfer of valence electron(s) from one atom to another.

Answer 26

Ionic bonding

Question 27

refers to the formation of a chemical bond between two or more atoms, molecules, or ions to give rise to a chemical compound.

Answer 27

Chemical bonding

Question 28

There are three main types of chemical bonding, namely,

Answer 28

ionic, covalent, and metallic bonding.

Question 29

, also called molecular bond, is the second type of chemical bonding characterized by sharing of electron pairs between two atoms.

Answer 29

Covalent bond
