the $-37$ after the name chlorine shows the number of nucleons - the protons and neutrons found in the nucleus.

the proton number shows the number of protons in the atom. this is found at the bottom-left of the element symbol in . for chlorine, this is $17$.

therefore, the number of neutrons in an atom of chlorine can be found by subtracting the proton number of chlorine from the of chlorine.

$37 - 17 = 20$

there are $20$ neutrons, $17$ protons and therefore $37$ nucleons in one atom of chlorine$-37$.

An atom of chlorine is represented by $""_17^37 Cl$. How many neutrons are in the nucleus of this atom?

We know that EVERY $Cl$ contains $17$ protons, massive, positively charged nuclear particles. This is what defines it as a chlorine atom (and in fact, given the atomic symbol $Cl$,...

Aside from neutrons, what else is found in the nucleus of an atom?

Well, the nucleus also contains protons, which are massive nuclear particles each with a formal positive charge. And the number of protons gives $Z$, the , which number determines the...

The mass of an atom may be determined by adding the masses of the protons and neutrons in the nucleus and then subtracting the mass defect. Why is it unnecessary to include the electrons when determining the mass of an atom?

A proton has has about 1836 times more mass than an electron and neutrons are almost the same mass as protons.

$"Atom W has 9 protons and 9 neutrons, Atom X has 8 protons and 9"$ $"neutrons. Atom Y has 9 protons, and 9 neutrons. Atom Z has 10 protons"$ $"and 10 neutrons."$ What are the isotopes?

And $Z$ defines the identity of the element: $Z=1,H;Z=2,He;..........Z=6,C;........Z=37, Ru...........$ You don't have to remember these numbers, because a Periodic Table will be supplied to you in every test of...

An average sample of chlorine contains 75.77% chlorine-35, with an atomic mass of 34.969 amu (atomic mass units), and 24.23% chlorine-37, with an atomic mass of 36.966 amu. What is the average atomic mass of chlorine?

The weighted average is the sum of each individual nuclide, multiplied by its isotopic abundance. So, we simply do the arithmetic: $0.7577xx34.969+0.2423xx36.966 = ???$ amu Then look at to...

An atom has 35 protons, 38 neutrons, and 35 electrons. What is the charge of the atom's nucleus?

The nucleus has a positive charge. The electron orbit has a negative charge. These two values are equal (35), giving the atom an overall charge of "neutral". Hope this helps...

When an atom of chlorine forms an ionic bond with an atom of sodium, what happens to the atom of chlorine?

The sodium atom loses its one valence electron to form a cation with a charge of +1, $Na^+$. Chlorine gains the electron to obtain a full valence shell and forms...

Sally is making a model of a Mg atom with an atomic mass number of 24. She has balls for the protons, neutrons, and electrons. She has added 6 neutrons to her model. How many more neutrons does she need to add to complete her neutral atom of magnesium?

$Z$, $"the atomic number"$ of magnesium is 12. This means that there are 12 positively charged nuclear particles. This defines the particle as a magnesium atom. To represent the $""^24Mg$...
