The answer is 3
Boron - B - Group IIIThe atomic number is 5.The mass number is 11.
Zink is a meta element. Atomic mass of it is 65. Atomic number of it is 30.
Argon is a period 3 element.
18 represents the atomic number for Argon. It is the number of protons and of electrons in an argon atom and defines its position in the periodic table.
The mass number of an atom of argon is 40. This number represents the total number of protons and neutrons in the nucleus of the argon atom.
The mass no of argon is 39.948
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.
The mass number of argon is 40, which is the total number of protons and neutrons in its nucleus. The atomic number of argon is 18, which represents the number of protons in its nucleus.
The most common isotope of argon is Ar-40, with a mass number of 40 and an atomic mass of approximately 39.948 amu.
The atomic number of argon is 18, which means it has 18 protons in its nucleus. The mass number of argon is 40, which is the sum of protons and neutrons in its nucleus.
The atomic mass of argon is approximately 39.95 atomic mass units.
To find the number of moles in 119.98 g of argon, divide the given mass by the molar mass of argon. The molar mass of argon is 39.948 g/mol. Therefore, 119.98 g รท 39.948 g/mol = 3.00 moles of argon.
It is 40!
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).
The relative atomic mass is 39.95
The number 40 in argon-40 represents the total number of protons and neutrons in the nucleus of an argon atom. It is the mass number of argon-40, which is the sum of the number of protons (18) and neutrons (22) in the nucleus.
