What is the mass number of an ion with 108 electrons, 158 neutrons, and a +1 charge? express your answer as an integer.

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

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
