there is no such element
Helium is odd as it has 2 valence electrons while others have 8 valence electrons.
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.
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.
Argon is a noble gas. It has a full valence shell and thus, 8 electrons.
Argon
When magnesium loses its valence electrons, it forms a cation with the atomic structure of neon. This is because it will lose its two valence electrons to achieve a full octet like the nearest noble gas, which is neon.
Argon(Ar) and Helium(He)
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).
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.
8 valence electrons- 1s22s2p63s2p6
Argon is a noble gas. All noble gasses have 8 valence electrons. Thus argon has 8 valence electrons as well.
there is no such element
All noble gasses have 8 valence electrons which means outer electrons. As for electrons overall, argon would have 18.
Helium is odd as it has 2 valence electrons while others have 8 valence electrons.
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.
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.
