Question

the table gives the numbers of protons, electrons, and neutrons in four atoms. based on the table, which atom has a charge of -1? atom number of protons number of neutrons number of electrons 1 9 8 9 2 9 9 8 3 9 9 10 4 9 10 9 1 2 3 4

Explanation:

Step1: Record la fórmula de carga

Carga = Número de protones - Número de electrones

Step2: Calcular la carga del átomo 1

Carga_1 = 9 - 9 = 0

Step3: Calcular la carga del átomo 2

Carga_2 = 9 - 8 = 1

Step4: Calcular la carga del átomo 3

Carga_3 = 9 - 10 = - 1

Step5: Calcular la carga del átomo 4

Carga_4 = 9 - 9 = 0

Answer:

3
