What is an ion (1 mark) what is the charge on a chloride ion (1 mark) what is an ionic bond (1 mark)

An ion is a positively or negatively charged atom formed by losing or gaining of electrons.

Chloride ion has a charge of -1

Ionic bond is the bond formed by cation and anion

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
