Argon has 18 protons and 22 neutrons in its nucleus giving it an Atomic Number of 18 and an atomic mass of 40.
What will be the atomic number of an atom if it has 18 electrons and 22 neutrons?
18 protons, 22 neutrons, 18 electrons
There are 18 protons from the argon element. There 18 electrons because it is neutral, and 22 neutrons because 40 – 18 = 22.
What has 18 protons and 20 neutrons?
You gots Z=18 , the atomic number, where Z is the number of nuclear protons. The number of protons defines the element....and thus we got calcium .... ....and with 20 neutrons we got the 38Ca isotope....the which is rather short-lived....
What is the mass number of an argon atom that has 18 protons and 22 neutrons *?
Argon in the atmosphere has three isotopes, all with 18 protons – but one type (called 36 Ar) has 18 neutrons and a relative mass of approximately 36 ; a second type (called 38 Ar) has 20 neutrons and a relative mass of approximately 38, and the final and most common type (called 40 Ar) one has 22 neutrons and a relative ...
What isotope has 18 protons and 22 neutrons quizlet?

Is the smallest unit that matter can be broken down into?
atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry.
What 2 elements have 10 neutrons?
All beryllium atoms have 5 neutrons in the nucleus and all fluorine atoms have 10 neutrons.
Where is Argon 36 found?
Argon constitutes 1.288 percent of the atmosphere by weight and 0.934 percent by volume and is found occluded in rocks . Although the stable isotopes argon-36 and argon-38 make up all but a trace of this element in the universe, the third stable isotope, argon-40, makes up 99.60 percent of the argon found on Earth.
Why does arsenic have 42 neutrons?
But since arsenic is monoisotopic, that number will tell you directly the atomic mass of its isotope. This means that arsenic’s stable isotope has an atomic mass of 74.992 u . ... Therefore, the stable arsenic isotope is arsenic-75, 75As , which has 33 protons and 42 neutrons in its nucleus.
