Question

Draw the geometric atomic structure of following element, showing clearly the {a} number of protons {b} number of electrons {c} number of neutrons.

${}_5{}^{}\mathrm{B}$¹¹

Answer 1

Boron ${}_5{}^{}\mathrm{B}$¹¹ — It is a chemical element with the atomic number 5

• it is a non-metal because it is an electron-deficient element.
• It is a low-abundant element that is found in the earth's crust and solar system.
• the Total number of electrons = atomic number (in a neutral atom).
• the total number of protons = atomic number.
• mass number = mass of neutrons + mass of protons.
• the total number of neutrons = mass number – the atomic number.

Thus, in ${}_5{}^{}\mathrm{B}$¹¹ number of protons is 5, the number of an electron is 5, and the number of neutrons is 6, their geometric structure is as follows-
