Why do atoms share electrons in covalent bonds? ?

Answer and Explanation:

Covalent bond is formed when electrons are shared by the atoms to fulfill their outermost shell.

In colvalent bond atoms shares electron to gain stability because if their outermost shell is not fulfilled then they are unstable.

So to gain stability electrons are shared by atoms in covalent bond , when they share electron their outermost shells are fulfilled and they become stable  

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
