How many protons and nuetron's do oxygen have?

An oxygen always has 8 protons and normally has 8 neutrons, but a very small minority of oxygen atoms are isotopes of oxygen-17 or oxygen-18 which contain 9 or 10 neutrons respectively.


If the isotopes oxygen-18 has 18 protons?

The atomic number of oxygen is 8. So it has 8 protons. And O-18 isotope has 10 neutrons.


How many neutrons are in the atom chlorine?

Every chlorine atom has 17 protons; 17 is the atomic number of chlorine. However, chlorine has two isotopes that are stable against radioactive decay. These have mass numbers of 35 and 37, which have 18 and 20 neutrons respectively.

How many protons neutrons and electrons are in chlorine 37?

Cl-37 : 17 protons , 20 neutrons , 17 electrons Compare with Cl-35 ; 17 protons , 18 neutrons, 17 electrons. These are two different and common isotopes of chlorine. Remember 'Different isotopes have a different number of neutrons'. Chemically they react the same.


Why do elements always have the same atomic numbers but not the same atomic mass?

Most elements have isotopes---atoms that have the same number of protons (and hence they are still that element) but different numbers of neutrons. For instance, sulfur found in nature has four stable isotopes: S-32 16 protons 16 neutrons S-33 16 protons 17 neutrons S-34 16 protons 18 neutrons S-36 16 protons 20 neutrons Each of these isotopes has a different mass, but all are sulfur because they have 16 protons.


How many protons and electrons does chlorine has?

Number of Protons = Number of electrons = 17.The number of neutrons depends on the isotope. Cl-35 and Cl-37 isotopes have 18 and 20 isotopes respectively.


How many protons neutrons and electrons are there in sulfur?

There are 16 protons, 16 neutrons and 16 electrons in a Sulfur atom. *note it's atomic number- this is the number of protons in an atom of an element. There must be the same number of electrons to balance the charge. The atomic weight minus the number of protons gives you the number of neutrons


Which atom will produce an ion with 15 protons 16 neutrons and 18 electrons?

A phosphorus atoms has 15 protons and will form an ion with 18 electrons. Phosphorus-31 is one of the isotopes.


How many protons neutrons and electrons in 40 Ar?

What element has 18 neutrons in its atom?

There are several. However, Chlorine is one. Chlorine-35 has 17 protons, 18 neutrons and 17 electrons in its isotopic atom. However, Chlorine-37 has 17 protons, 20 neutrons and 17 electrons in its isotopic atom.


What is different about oxygen-17 and oxygen-18?

These are both isotopes of oxygen, meaning that they have different numbers of neutrons but the same number of protons.
