How many protons and neutrons are in an atom of the element

Question

How many protons and neutrons are in an atom of the element

17-ATOMIC NUMBER

CI

35-ATOMIC MASS

17PROTONS AND 17 NEUTRONS

17 PROTONS AND 18 NEUTRONS

18 PROTONS AND 17 NEUTRONS

18 PROTONS AND 18 NEUTRONS

Answer 1

the number of protons in an atom is defined by the atomic number, so in this case it would be 17 protons. then to find the number of neutrons you can take

number of neutrons = atomic mass - atomic number

=35 - 17

=18

meaning that an atom of Chlorine-35 has 17 protons and 18 neutrons

Answer 2

³⁵Cl₁₇ - this is the representation of chlorine atom, it shows that it has atomic number 17 and mass number 35.

Now what does it means?

Atomic number is the number of protons present in the nucleus of an atom, which is responsible for properties of that particular element. If it will have 17 protons then it will always be chlorine atom.

Mass number - is the total number of protons and neutrons present in the nucleus of an atom. As the electrons have negligible mass the mass of nucleus will be atomic mass.

So, here we can say that in chlorine atom

no. of protons - 17

No. of proton + No. of neutrons = 35

so no. of neutrons will be - 35 - 17 = 18.

Answer 3

Chlorine has an atomic number of 17 and an atomic mass of 35,45 making it consist of 17 protons, 17 electrons, and 18 neutrons.

Answer 4

To provide the specific number of protons and neutrons in an atom of a particular element, I would need to know which element you are referring to. Each element on the periodic table has a unique number of protons and neutrons. Could you please specify the element you would like information about?

Answer 5

Chlorine has an atomic number of 17 and an atomic mass of 35.45, meaning that an atom of chlorine consists of 17 protons, 17 electrons, and 18 neutrons.

Typically how I remember the number of neutrons is by either looking at my reference table or knowing that the number of protons is the atomic number, and the number of protons plus neutrons is the atomic mass.

Your answer should be:

17 PROTONS AND 18 NEUTRONS

Answer 6

Hi Tasha

You can look up elements, atoms and their Isotopes in your text or online if you are learning about the Periodic Table that information is available as well

In elements, the number of electrons and protons match as a matter of electronic balance. The Atomic Number = number of protons=number of electrons then there are 17 protons. The other item you may want to look into is Isotopes because three out four Chlorine atoms weigh 35 amu and have 18 neutrons.

I hope this helps
