Respuesta :
If an element loses an electron it acquires a positive charge so its charge will be positive.
Answer: It will carry a charge of +1 units.
Explanation:
Ions are formed when an atom looses or gains electrons.
When an atom looses its electrons, it will lead to the formation of positively charged ion known as cation.
When an atom gains electrons, it will lead to the formation of negatively charged ion known as anion.
Rubidium is the 37th element of the periodic table having electronic configuration of [tex][Kr]5s^1[/tex]
We are given that this element looses 1 electron and thus, it will lead to the formation of a positively charged ion carrying a 1 unit of charge.
The ion formed will be [tex]Rb^+[/tex]
Hence, it will carry a charge of +1 units.
