Question

${}_1{}^{}\mathrm{H}$¹ is isotopes of hydrogen. Draw their structures showing clearly the number of protons; neutrons and electrons. Also, state their common names.

Answer 1

Isotopes — A element that has the same atomic number but differs in mass number is considered an isotope.

• Isotopes are members of an element that all have the same number of protons but different numbers of neutrons.
• The number of protons in a nucleus determines the element's atomic number on the periodic table.
• There are two main types of isotopes, and these are radioactive isotopes and stable isotopes.
• stable isotopes have a stable combination of protons and neutrons.
• In isotopes, stable nuclei do not undergo decay.
• The radioactive isotopes do not pose dangerous effects on living things.
• for example — ${}_1{}^{}\mathrm{H}$¹ ,${}_1{}^{}\mathrm{H}$² , ${}_1{}^{}\mathrm{H}$³ , ${}_6{}^{}\mathrm{C}$¹², ${}_6{}^{}\mathrm{C}$¹⁴, ${}_8{}^{}\mathrm{O}$¹⁶,${}_8{}^{}\mathrm{O}$¹⁸ , ${}_{17}{}^{}\mathrm{Cl}$³⁵ , ${}_{17}{}^{}\mathrm{Cl}$³⁷ etc
• Number of protons = Atomic number
• Number of electrons = Atomic number
• Number of neutrons = Mass number – Atomic number

Thus, in ${}_1{}^{}\mathrm{H}$¹ number of the proton is 1, the number of an electron is 1, the number of neutrons is 0, the common name is protium and their structure follows
