How many nutrons does argon have?
There are 3 Isotopes with the following mass numbers: Argon 36 Argon 38 Argon 40 Argon has an atomic number of 18 (it therefore has 18 protons in its nucleus and 18 electrons flying round it). To get the number of neutrons one subtracts the atomic number from the mass number. This means that some Argon atoms have 18 neutrons, some 20 neutrons and some 22 neutrons the isotope with 22 neutrons is the most common and forms 99.6% of all Argon.
How many atoms are in a 12.0 grams sample of sodium?
There are approximately 6 x 10^22 atoms in a 12.0 gram sample of sodium.
How many protons nuetrons and electrons does argon have?
Argon has 18 protons, 22 neutrons, and 18 electrons. The number of protons determines the element, so argon always has 18 protons. The sum of the protons and neutrons gives the atomic mass of argon, which is around 40.
What is the mass in grams of 3.40x10 22 atoms He?
To find the mass of 3.40x10^22 helium atoms, you need to know the molar mass of helium, which is 4.0026 g/mol. So, the mass of 3.40x10^22 helium atoms would be 3.40x10^22 atoms * (4.0026 g/mol/6.022x10^23 atoms/mol) ≈ 2.27 grams.
How many protons nuetrons and electrons are in argon?
Argon has 18 protons, 22 neutrons, and 18 electrons.
