Question

Draw the geometric atomic structure of following elements, showing clearly the {a} Number of protons {b} number of electrons {c} number of neutrons. ${}_{12}{}^{}\mathrm{Mg}$²⁴

Answer 1

Magnesium ${}_{12}{}^{}\mathrm{Mg}$²⁴ — It is a chemical element with the atomic number 12

• it is a shiny gray solid which shares many physical and chemical properties with the other five alkaline earth metals
• Total number of electron = atomic number
• total number of proton = atomic number
• mass number = mass of neutrons + mass of protons
• total number of neutron = mass number – atomic number

Thus, in ${}_{12}{}^{}\mathrm{Mg}$²⁴ number of protons is 12, number of electron is 12, and number of neutrons is 12 , their geometric structure as follows
