What is the mass number of a CI atom that 17 protons and 18 neutrons?
Chlorine is a non metal element. Mass number of it is 35.
What element has 18 protons 20 nuetrons and 18 electrons What is its atomic number?
The element with 18 protons is argon (Ar), with atomic number 18. Its mass number is calculated by adding the protons and neutrons, so 18 protons + 20 neutrons = mass number 38 for this particular isotope of argon.
What element has 18 protons and 22 neutrons?
The element with 18 protons and 22 neutrons is argon. Argon has an atomic number of 18, which corresponds to the number of protons, and an atomic mass of 40 (approx.), which is the sum of protons and neutrons.
The number of neutrons in an isotope of argon that has a mass number of 40 and an atomic number of 18?
The atomic number of argon (Z) is 18, which means it has 18 protons. The mass number (A) is 40, so subtracting the atomic number from the mass number gives you the number of neutrons. In this case, 40 - 18 = 22 neutrons.
How many neutrons does the element argon have?
The element argon has 22 neutrons. It has 18 protons and 18 electrons, giving it an atomic number of 18. The number of neutrons is calculated by subtracting the atomic number from the atomic mass, which is 40 for argon (obtained by rounding the atomic weight to the nearest whole number).
What is the mass number of a CI atom that 17 protons and 18 neutrons?
Chlorine is a non metal element. Mass number of it is 35.

The number of neutrons in an isotope of argon that has a mass number of 40 and an atomic number of 18?
The atomic number of argon (Z) is 18, which means it has 18 protons. The mass number (A) is 40, so subtracting the atomic number from the mass number gives you the number of neutrons. In this case, 40 - 18 = 22 neutrons.
How many neutrons does the element argon have?
The element argon has 22 neutrons. It has 18 protons and 18 electrons, giving it an atomic number of 18. The number of neutrons is calculated by subtracting the atomic number from the atomic mass, which is 40 for argon (obtained by rounding the atomic weight to the nearest whole number).
What is the mass number for oxygen 18?
The mass number for oxygen-18 is 18. This is calculated by adding together the number of protons and neutrons in the nucleus of an oxygen-18 atom. It is a stable isotope of oxygen with 8 protons and 10 neutrons.
What is the mass number of an atom with 18 protons 22 neutrons and 18 electrons?
if you were to count the individual weight of all the protons neutrons and electrons you will get 40. however this is not the case when they are joined together due to something call the strong neuclear force which causes the atom to weigh 39.9
What is the atomic and mass number of fluorine 18?
Fluorine is a non metal element. Mass number of it is 19.
If the atomic mass of chlorine is 35 how many neutrons does it have?
The number of neutrons in chlorine is 18 (no of neutrons=atomic mass-no of protons=35-17=18)
How many neutrons are in 18-Argon?
Argon has an atomic number of 18, which means it has 18 protons. To find the number of neutrons, you would subtract the atomic number from the mass number. If you specifically mean the isotope 18-Argon, it would have a mass number of 18, so it would have 18 - 18 = 0 neutrons.
What is the science element that has 18 neutrons?
Chlorine maybe? It has 17 protons and a mass of 35, so 35-17= 18 neutrons.
What element has a mass number of thirty-five?
Chlorine:Atomic number = 17Mass number = 35Number of protons = 17Number of electrons = 17Number of neutrons = 35-17 = 18
