How many protons neutrons and electrons in 40 Ar?
18 protons 18 electrons 22 neutrons
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.
How many protons nuetrons and electrons are in argon?
Argon has 18 electrons and protons...Neutrons is 22
What is the protons number neutrons number and electrons number in argon?
Protons: 18Neutrons: 18, 20 and 22. Electrons: 18
How many protons neutrons and electrons are in argon 39?

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 20 protrons 20 neutrons and 18 electrons?
The element with 20 protons, 20 neutrons, and 18 electrons is calcium. Calcium has an atomic number of 20, which tells us the number of protons in the nucleus. The number of protons and electrons should be equal for a neutral atom, therefore in this case the element is calcium.
How many electrons does an element have if it has 17 protons and 18 neutrons?
If an element has 17 protons, it will also have 17 electrons since atoms are electrically neutral. Adding the number of neutrons (18) to the number of protons (17) gives us the mass number of the element, which in this case would be 35.
How many protons neutrons and electrons are in Ar?
18 protons and electrons and 22 neutrons.
