Solution
Identify the number of electrons and protons in Hydrogen:
Atomic numberNumber of electronsNumber of protons
Thus,
Number of electrons
Number of protons
Identify number of neutrons in Hydrogen:
Mass numberNumber of protonsNumber of neutrons
Thus,
Number of neutronsMass numberNumber of protons
Thus,
Number of neutrons
Thus, the table is as follows:
Name of
the element
Symbol
of the element
Atomic
number
Mass
number
No. of
protons
No. of
electrons
No. of
neutrons
Electronic configuration Hydrogen H 1 1 1 1 0 K=1 L M N
Identify the number of electrons and protons in Hydrogen:
Atomic numberNumber of electronsNumber of protons
Thus,
Number of electrons
