X atom (means no radical) having 19 electrons will be sure potassium, according to the defination of atomic number. Now, the the valancy of an element is equivalent to the number of electrons present in its outermost shell.

Rh has 9 from itself, and H and Cl add 1 each; hence in this assignment above I thought one would end up with: 9+1+1+2+2+6=21 valence electrons.

Examples include hydrogen (H), lithium (Li), and sodium (Na). Any element in group 18 has eight valence electrons (except for helium, which has a total of just two electrons). Examples include neon (Ne), argon (Ar), and krypton (Kr). Oxygen, like all the other elements in group 16, has six valence electrons.

The Carbonate (CO2−3) Ion Carbon has 4 valence electrons, each oxygen has 6 valence electrons, and there are 2 more for the −2 charge. This gives 4 + (3 × 6) + 2 = 24 valence electrons.

Aluminium has 03 valence electrons,out of its total of thirteen electrons. Explanatory justification: The electronic configuration of Aluminium applying the noble gas standard is: There you see that 3rd shell is valence,with 2ēs of 3s and 1ē from p to make a total of 03 valence electrons.

Determine the total number of valence electrons in the molecule or ion. Each hydrogen atom (group 1) has one valence electron, carbon (group 14) has 4 valence electrons, and oxygen (group 16) has 6 valence electrons, for a total of [(2)(1) + 4 + 6] = 12 valence electrons.

Below is the Lewis dot structure for a Br− ion, which has eight valence electrons. The extra valence electron gives it a negative charge.

A potassium ion, K+ has an atomic number of 19 and a mass number of 39 So there are 19 protons and 39-19 = 20 neutrons. To become a positive ion it looses its valence electron with its valence shell and becomes K+ by achieving the configuration of 2,8,8,1 with 3 energy levels/shells.

In any event, you must start with Xe and 4 O atoms, and note that there are 8 + 4x6 = 32 total valence electrons. The Xe atom is attached to all four oxygen atoms. Four bonds = 8 electrons, so you have 24 electrons left.

Therefore Mercury has 2 valence electrons. Since Mercury can donate this two 6s electrons, its valency is also 2. Thus, Valency/valence electrons of Mercury is/are 2.
