Data given
Number of electron = 108
Number of neutron = 158
Required
Mass number=?
Solution
As we know that mass number = No of proton + No of neutron
In any neutral atom the number of proton is always equal to number of electron
So number of proton will be = 108
However the atom has +1 charge which means that one proton is less than no of electron so proton number is 107.
Put values in above formula, we will get
Mass number= 107+108
= 215 Mass number
A Punnett Square is a chart in which you cross two parents' offspring to figure out what traits their offspring may have. It helps give an estimate of the probability of the child having different attributes, such as eye color or hair color through the use of dominant and recessive alleles.
