Question

A lithium atom contains 3 protons, 4 neutrons and 3 electrons. What would be formed it one proton if one proton is added to this atom

Answer 1

Answer: Beryllium ion (Be+)

Step-by-step explanation:

Addition of one proton to Li would lead to formation of Beryllium ion since Beryllium contains 4 protons and 4 electrons to counter the charges and make the element neutral. But in this case, Be+ is formed to show a deficit of one electron (e-).

Answer 2

Beryllium ion.

Step-by-step explanation:

• Adding one proton to an atom of lithium which have 3 protons, 4 neutrons and 3 electrons will form a beryllium ion.
• The new atom formed after adding a proton will have 4 protons and 4 neutrons since to have a mass number of 9 then it has to form an ion.
• Beryllium is of gray colour, strong, light-weight, and used as hardening agent in different alloys. It has one of the highest m.p(melting point) in the light metals.

Result: On adding a proton in lithium will form a beryllium ion.
