Question

complete the sentences. the number of protons in the fluorine atom is blank. the number of electrons. so the fluorine atom has a blank.

Explanation:

Step1: Count protons in nucleus

In the atomic model, protons are yellow with +. Count them: let's see the nucleus has yellow (proton) circles. Let's count: looking at the diagram, the number of protons (yellow +) is 9.

Step2: Determine electron count

In a neutral atom, number of protons = number of electrons. So electrons (blue -) count: let's count the blue electrons in the shells. The inner shell? Wait, the diagram shows electrons in the orbits. Let's count: the electrons are the blue dots. Let's count them: 9 (since proton count is 9, neutral atom has equal protons and electrons). So the number of protons is 9, and since protons = electrons in neutral atom, electrons are also 9, so the fluorine atom has a neutral charge (or we can say the charge is 0, but the question might be about the number of protons and electrons, and then the charge or just the count. Wait, the first blank: number of protons in fluorine atom is 9 (since fluorine has atomic number 9, protons = atomic number). Then, the number of electrons: in neutral atom, electrons = protons, so 9. So the fluorine atom has a neutral charge (or we can say the number of protons equals electrons, so charge is 0, but maybe the first blank is 9, second blank: equal to, third blank: neutral charge or 9 electrons. Wait, let's re-express.

First, count protons: the yellow + in nucleus. Let's count the yellow circles: let's see the nucleus has, let's count the yellow (proton) and gray (neutron). The yellow ones: let's count. Let's see the diagram: the nucleus has, say, 9 yellow (proton) and some gray (neutron). So protons: 9. Then electrons: the blue dots in the orbits. Let's count the blue electrons: let's see the inner orbit? Wait, the diagram shows two orbits? Wait, no, the electrons are in the circles. Let's count the blue dots: 9. So in a neutral atom, protons = electrons, so the number of protons in fluorine atom is 9, the number of electrons is equal to protons, so fluorine atom has a neutral charge (or the number of electrons is 9, so the atom is neutral).

So step1: count protons (yellow +) in nucleus: 9. Step2: electrons (blue -) in orbits: 9. So protons = electrons, so the atom is neutral.

Answer:

The number of protons in the fluorine atom is \(\boldsymbol{9}\), the number of electrons is equal to the number of protons, so the fluorine atom has a \(\boldsymbol{neutral}\) charge (or the number of electrons is \(\boldsymbol{9}\)). (Depending on the exact blanks, but likely first blank: 9, second: equal to, third: neutral or 9 electrons. If the blanks are for number of protons: 9, then "equal to" for the relation, then "neutral" or "9 electrons" for the last part.)
