Users sort answers between categoriesSorting30sS8P1e - Q7
How many protons does this atom have AND how did you come to that conclusion?
This atom has 6 protons. I know this because this diagram shows that there are 6 neutrons in the energy levels and protons and neutrons are always the same.
This atom has 6 protons. I know this because this diagram shows that there are 6 electrons in the energy levels and protons and electrons are always the same.
The atom has 5 protons. I know this because this diagram shows that there are 5 electrons in the outermost energy level and valence electrons and protons are always the same.
The atom has 2 protons. I know this because this diagram shows that there are 2 neutrons on the first energy level and protons and neutrons are always the same.
60sS8P1e - Q8
How many neutrons does chlorine have and how did you come to that conclusion?
35 neutrons because that is the mass number of chlorine.
17 neutrons because that is the atomic number of chlorine.
18 neutrons because I rounded the mass number of 35.45 to 35 and then subtracted the atomic number 17.
19 neutrons because the mass number is 36 and then I subtracted the atomic number 17.
