What is the mass number for argon 37?

The mass number for argon-37 is 37. It is calculated by adding the number of protons and neutrons in the nucleus of the argon atom.


What is the number of neutrons in argon?

The number of neutrons in an argon atom is 22. This is calculated by subtracting the atomic number of argon (18) from its atomic mass number (40).


What is the number of neutrons in a atom of argon?

The number of neutrons in an atom of argon is typically 22. Argon has an atomic number of 18, which means it has 18 protons in its nucleus. The number of neutrons is calculated by subtracting the atomic number from the atomic mass, which is approximately 40 for argon.


The actual mass of an atom of argon is is 6.63x10-24g How many atoms are in a 40.0-g sample of argon?

To find the number of argon atoms in a 40.0-g sample, you first need to calculate the number of moles of argon in the sample using the molar mass of argon (39.95 g/mol). Then, you can use Avogadro's number (6.022x10^23 atoms/mol) to determine the number of atoms in that many moles of argon.


Why does the argon atom has a lower atomic number but a greater massnumber than the potassuim atom?

Argon has a lower atomic number than potassium because it has fewer protons in its nucleus. However, argon has a greater mass number than potassium because it has more neutrons in its nucleus. The mass number of an atom is determined by the sum of protons and neutrons in its nucleus.


How many neutrons are in the nucleus of an atom of argon-42?

Neutrons = 24 Protons = 18 Electrons = 18


What does the number 40 in argon-40 represent?

It is the mass number, i.e., the total number of protons and neutrons in argon and is ofter used to calculate the number of neutrons present. As the atomic number (or the number of protons) for argon is 18, there will be 22 neutrons in Argon-40 isotope.


What is argon's mass number?

The mass no of argon is 39.948


How many protons and neutrons does argon atom have?

Protons = 18neutrons = 22 (for the most stable isotope of argon, Ar-40)


What is the atomic mass of argon-36?

An isotope is an atom with a different number of neutrons. The number of neutrons is the only particle that changes. Electrons will stay the same. Therefore, the number of electrons is the same as the atomic number, which is 18.


An atom has 18 protons 18 electrons and 20 neutrons. This atom has?

This atoms has an atomic number of 18 and an atomic mass of 38.


What is the mass number for Argon-37?

You actually just answered your own question. The Isotope Ar-37 has a mass of 37. Most elements and Isotopes are commonly phrased like "Element-Mass"
