Yes. The ion Ca2+ and the element argon, have 18 electrons each.
Argon-38 is a specific isotope of argon, and it has 18 electrons since the number of electrons in an element is determined by its atomic number.
Argon has 18 electrons.
Argon does not contain valence electrons.
18 protons and 22 neutrons in the most commonly occurring isotope argon-40. In argon-36 there are 18 neutrons but this isotope is only present in nature at 0.34%
Argon is atomic number 18. It would therefore have 18 protons. Having 18 protons would mean that Argon must also have 18 electrons.
Argon has 18 electrons.
The electronic configuration of Argon is [Ne] 3s2 3p6. This means it has 18 electrons arranged in energy levels around the nucleus, with the first two electrons in the 3s orbital and the next six electrons in the 3p orbital.
There are 6 2p electrons in argon.
Argon has 18 electrons.
The amount of electrons is Argon is 18.
There are 18 electrons and protons each in argon atoms.
Argon has 8 valence electrons.
Argon has 8 valence electrons.
Argon is a noble gas. All noble gasses have 8 valence electrons. Thus argon has 8 valence electrons as well.
Electrons are always negative. There is no neutral electrons.
No. The atomic number of argon is 18. So it has 18 protons and 18 electrons (out of these, 8 electrons are valence electrons and belong to the outermost shell).
