Question

you are given an element X atomic number=7 mass number =14 then find out number of electron ,proton,and neutron in X​

Answer 1

hey mate!

Atomic number -Z=13 .

Element is aluminum .

mass number is 27

Element is represented by    ²⁷Al₁₃

Number of protons=13

Mass number=number of protons + Number of neutrons

So, Number of neutrons=Mass number - number of protons

                                          =27-13

                                           =14 neutrons

electronic configuration: 1s²2s²2p⁶3s²3p¹

Electrons arranged in Shells are shown in attachment :

Answer 2

it is not aluminium it is nitrogen
