Answer 1

Explanation:

True friends are really bestowed to someone special in the life after hard works. Real friendship is the true relationship of two or more people where only trust exists without any demands. One always ready to give care, support and other needed things to other in the true friendship. Friends are very important in the lives of everyone as they play a great role in standing someone needy person by giving love, care and emotional support. Friendships can be between two or more people of any age group, sex, position, race or caste. However, generally friendship occurs between people of same age.

Some people successfully carry their childhood friendship for whole life however someone get break in between due to the misunderstanding, lack of time or other problems. Some people tend to have many friends at their kindergarten or primary level but only one or no one they carry in later life. Some people tend to have only one or two friends which they carry in later life even in old age very wisely. Friends can be from outside the family (neighbour, relative, etc) or inside the family (one of the family members).

Friends can be both types good or bad, good friends lead us on good path whereas bad friends lead us on bad path, so we should be careful while choosing friends in life. Bad friends can be proved very bad to us as they are quite enough to ruin our life completely. We need someone special in our life to share our feelings (happy or sad), to talk someone to remove our loneliness, to make laugh someone sad and many more. In the good company of our friends we get motivation to do any hard work in life and it becomes easy to pass bad times cheerfully.

Answer 2

Electronic configuration:

⇒ The atomic number of nitrogen = 7

The electronic configuration of 7N = 2,5

⇒ The atomic number of carbon = 6

The electronic configuration of 6C = 2,4

⇒ The atomic number of oxygen = 8

The electronic configuration of 8O = 2,6

⇒ The atomic number of boron = 5

The electronic configuration of 5B = 2,3

⇒ The atomic number of aluminum = 13

⇒ The electronic configuration of 13Al = 2,8,3

Among the given elements, oxygen is the most electronegative element.

Explanation: Electronegativity is the ability of an atom to attract shared pair of electrons.

⇒ Electronegativity increases as we move from left to right in a period.

⇒ Electronegativity decreases as we move down the group.

⇒ By combining these two facts, oxygen is the most electronegative element.

Note:

Electronegativity increases along a period because-

⇒ The atomic radius goes on decreasing as we move from left to right due to which the attraction between the outer electrons and nucleus increases.

Electronegativity decreases along a group because-

⇒ The atomic radius goes on increasing as we move from top to bottom due to which the attraction between the outer electrons and nucleus decreases..
