2018年2月18日 · 8 Argon is a noble gas with an electron configuration of [Ne]3s^2\3p^6. So, it has 3 electron shells, and that will be its valence shell. In the third shell, it holds a total of 2+6=8 electrons, so it has 8 valence electrons.

This means that calcium #s^2# has 2 valence electrons it readily gives away in order to seek the stability of the octet. This makes calcium a Ca+2 cation. Chlorine is a Halogen in the 17th column or #s^2p^5# group. Chlorine has 7 valence electrons. It needs one electron to make it stable at 8 electrons in its valence shells.

How many argon (Ar) atoms are there in 1.5 x 102 g of argon? How many valence electrons are in each respective group on the periodic table? Give the electron configuration for potassium. How many valence electrons does it have? How many valence electrons do most of the noble gases have? A. 1 B. 2 C. 7 D. 8; How many valence electrons does Ne have?

2024年5月26日 · Valence electrons are the outer layer of electrons, the part that reacts. Argon is a noble gas, so it has a full valence electron level. It has eight valence electrons.

2024年5月23日 · Since Argon (Ar) is a noble gas (meaning it has a full valence shell), it has 8 electrons. It's atomic number is 18, so the first shell has 2 electrons, the second shell has 8 electrons, and the ...

2024年5月31日 · The number of valence electrons is dependent on which group of the periodic table the element is in.Since Argon is in group 8, it has a total of 8valence electrons. S2 Cl1 K1 plus and Ca2 plus are ...

2024年5月30日 · Argon has 8 valence electrons and a valence number of 0. It is a noble gas and does not readily form chemical bonds. As a result, its oxidation number is typically 0 in compounds.

Valence electrons are the electrons present in the outermost shell of an atom. You can easily determine the number of valence electrons an atom can have by looking at its Group in the periodic table. For example, atoms in Groups 1 and 2 have 1 and 2 valence electrons, respectively. Atoms in Groups 13 and 18 have 3 and 8 valence electrons ...

2024年5月27日 · All of the noble gases except helium have 8 valence electrons: neon, krypton, argon, and radon. ... An element with 7 valence electrons is typically more reactive than an element with 8 valence ...

In the case of argon, it has 18 protons and thus will be neutral if it has 18 electrons in total between all its shells. Answer and Explanation: 1 A neutral atom of argon will have eight valence electrons.
