According to the octet rule, a magnesium atom has a tendency to

Question 10 options:

gain one electron.

lose two electrons.

lose one electron.

Question 11 (1 point)

In a same group, electronegativity increases from bottom to top so nitrogen is more electronegative than phosphorus.

HCl

Question 15 (1 point)

A covalent bond is formed when two atoms

Question 15 options:

share one or more pairs of electrons with each other.

gain electrons.

share an electron with each other.

Question 16 (1 point)

On a same period, electronegativity increases from left to right so oxygen is more electronegative than carbon.

Question 16 options:

NaCl

K2SO4

NF3

Explanation / Answer

9) NF3

10) LOSE TWO ELCTRONS.

BECAUSE BY LOOSING THE TWO ELECTRONS ,Mg GETS NEON NOBLE GAS CONFIGURATION

11) True

becuase as the atomic size increases from nitogen to phosphrous ,the tendency to attarct the sahred pair of electrons is decreases.consequently electronegativity decreases

12) always psoitive

because cations are formed by loss of electrons.as result they get negative charge

13) ionic bond

because we are written BH3 as BH2^+ AND H^-1

14) Na2O

15) share one or more pairs of electrons with each other.

16) True

becuase as the atomic size decreases from nitogen to phosphrous ,the tendency to attarct the sahred pair of electrons isdecreases.conseqently electronegativity also increases.
