Question

isotopes
all atoms of an element have the same number of protons. however, atoms of the same element may have different numbers of neutrons. isotopes of an element have the same number of protons but different numbers of neutrons. since isotopes of an element have different numbers of neutrons, they also have different mass numbers.
sizes of dogs dogs come in a variety of sizes. the mass of each dog can be large or small, but they are all still dogs. their dna determines they are dogs.
isotopes of oxygen similarly, atoms may have different numbers of neutrons and different masses but still be the same type of atom. all three of these atoms are isotopes of oxygen. they have 8 protons, but different numbers of neutrons.
13 sep communicate information how does the overall charge of oxygen - 16 compare to the overall charge of oxygen - 17 and oxygen - 18? use the models of isotopes to help explain your answer.

Explanation:

Step1: Recall charge - determining factors

The overall charge of an atom is determined by the difference between the number of protons (positively - charged) and electrons (negatively - charged). Neutrons are neutral and do not contribute to the charge.

Step2: Analyze oxygen - 16

Oxygen - 16 has 8 protons and 8 electrons. The charge calculation is \(+ 8+( - 8)=0\).

Step3: Analyze oxygen - 17

Oxygen - 17 has 8 protons and 8 electrons. The charge calculation is \(+8+( - 8)=0\).

Step4: Analyze oxygen - 18

Oxygen - 18 has 8 protons and 8 electrons. The charge calculation is \(+8+( - 8)=0\).

Answer:

The overall charge of oxygen - 16, oxygen - 17, and oxygen - 18 is the same, all equal to 0. This is because in each isotope of oxygen, the number of protons (positively - charged particles) is equal to the number of electrons (negatively - charged particles), resulting in a net charge of zero.
