Question

in an ion, there are positively charged protons and negatively charged electrons:

• every proton has a charge of +1.
• every electron has a charge of −1.

the charge of an ion is the sum of the positive and negative charges of its protons and electrons.
create an expression that can be used to find the charge of a fluorine ion that has 9 protons and 10 electrons. move values to the lines to create the expression.
(__)×() + ()×(__)
values: −1, +1, 9, 10

Explanation:

Step1: Determine proton contribution

Each proton has a charge of +1, and there are 9 protons. So the expression for proton charge is \(9 \times (+1)\).

Step2: Determine electron contribution

Each electron has a charge of -1, and there are 10 electrons. So the expression for electron charge is \(10 \times (-1)\).

Step3: Combine the two contributions

To find the total charge of the ion, we add the proton charge and the electron charge. So the expression is \((9 \times +1)+(10 \times -1)\).

Answer:

\((9)(+1)+(10)(-1)\)
