Annotate the symbol by the reference image. Then, explain why this symbol represents an ion and how many electrons it has.

• the name of the element
• the charge
• the mass number
• the atomic number

since the symbol has a "+1" sign at the top right corner it represents a positively charged ion.

it has 4 electrons as it has "+1" symbol meaning it lost one electron out of initially 5 electrons present.

name of element = Boronthe charge = +1the mass number = 11the atomic number = 5
