How many electrons are in argon - 40?
Argon-40 has 18 electrons. This is because argon has an atomic number of 18, which indicates the number of protons (and electrons) in a neutral atom of argon.
What is the mass number of the atom of argon?
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.
How many protons nuetrons and electrons does argon have?
In order to answer this question, the specific isotope of argon must be known. However, I will answer it using argon-40 because it makes up over 99% of the atoms of argon. Argon-40 has a mass number of 40, meaning that the sum of protons and neutrons in the nuclei of its atoms is 40. In order to use this information to determine the numbers of protons and neutrons, you also need to know the atomic number, which is the number of protons in the nucleus of its atoms. Argon's atomic number is 18, so we know that all argon atoms have 18 protons. To calculate the number of neutrons, we subtract the atomic number from the mass number, which is (40-18)=22 neutrons. The number of electrons equals the number of protons in a neutral atom, so argon atoms have 18 electrons. So, to sum things up, neutral atoms of argon-40 contain 18 protons, 22 neutrons, and 18 electrons.
If an atom has a mass number of 40 and an atomic number of 20 how many electrons does it have?
There are many isotopes that have a mass number of 40. Calcium 20 has a mass number of 40 but so does potassium 21 and Argon 22. Calcium twenty however is probably the one you want as it is more common then the other isotopes listed.
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 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 element has 18 neutrons in its atom?
There are several. However, Chlorine is one. Chlorine-35 has 17 protons, 18 neutrons and 17 electrons in its isotopic atom. However, Chlorine-37 has 17 protons, 20 neutrons and 17 electrons in its isotopic atom.
What is the total number of electrons in atom of an element with an atomic number of 18 and a mass number of 40?
ARGON has 18 electrons, with an atomic number of 18 and an Atomic Mass of 40. It has 22 neutrons, is considered a Nobel gas, in that it is inert under most conditions, and is colorless.

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.
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.
How many protons are in a neutral atom of Ar-40?
Any atom of Argon (Ar) will have 18 protons regardless of charge or isotope.
