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?

The second is also

potassium

with 18 protons and 22 neutrons in each atom; it is slightly heavier. The third is calcium, with 20 protons and 20 neutrons in each atom; it is the heaviest of the three samples.”

What element has 18 protons and 21 neutrons?

#18 –

Argon

– Ar.

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.

What has a mass number of 24 and 13 neutrons?

If an atom has a mass number of 24 and also has 13 neutrons, the atomic number of the atom will be 11 and the atom will belong to the

element sodium

….
