Mostly they are s or p electron sub-orbitals in the same (outer) shell.
In the transition metals sometimes one electron from a higher d orbital gets involved ( e.g. to reach the oxidation states Fe2+ and Fe3+).

∙ 13y agoThe electron configuration of an atom is a numerical representation of the number of electrons in an atom. The numerical representation is divided into levels and sub levels identified by the period and group in which the atom is in
Period ----- Shell ----- Atom pairs
1 ------------- s ------------- 1
2 ----------- s, p -----------1, 3
3 ----------- s, p -----------1, 3
4 --------- s, p, d -------- 1, 3, 5
5 --------- s, p, d -------- 1, 3, 5
Each pair represent 2 atoms. The s shell can hold 2 electrons, the p shell can hold 6 electrons, and the d shell can hold 10 electrons
The valence of an atom is also identified by the shell and sublevel it is in. All the valence of an electron tell you is how many electrons exist in it's outermost shell

Have two valence electrons and get to a stable electron configuration by using two electrons?
an element with 2 valence electrons can obtain a stable electron configuration by "kicking out" two electrons to have the same electron config as the noble gas in the previous period
How many valance electrons are there in Fr plus?
Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.
What noble gas has the same electron configuration as silicon?
Silicon has 4 valence electrons. No noble gases will have 4 valence electrons.
Does H and HE have the same valence electron configuration?
Hydrogen and helium have different valence electron configurations. Hydrogen has one valence electron, and helium has two valence electrons. However, hydrogen does typically form covalent bonds in which it shares an electron, and thereby gains an effective electron configuration of two, like helium. Hydrogen also can form the H+ ion which has no electrons.
How do you find the number of valence elections?
To find the number of valence electrons for an atom, you need to look at its electron configuration. The valence electrons are the electrons in the outermost energy level of an atom. You can determine the number of valence electrons by looking at the electron configuration or the periodic table. For main group elements (Groups 1, 2, 13-18), the number of valence electrons is given by the group number. For example, group 1 elements have 1 valence electron, group 2 have 2 valence electrons, and so on.
What is the valence electron configuration for the phosphorus atom?
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.

How many valence electrons does ribidium have?
Rubidium is in group 1. The electron configuration is [Kr] 5s1. It has one valence electron.
How many valence electrons does the element lawrencium?
Lawrencium is a trivalent chemical element.

How many valence electrons does an atom of potassium have?
4
How many valence electrons does a chlorine atom have if its electron configuration is Ne3s23p5?
With an e- configuration of [Ne] 3s23p5, the atom will be found in Group VII A, meaning that there are 7 valence electrons.
How many valence electron shells do titanium have?
Titanium has the valence electron configuration of [Ar] 3d2 4s2. This means that Ti has 2 valence electrons, lying in the 4th s orbital. Note the relationship between the d-orbital and valence electrons is more complicated, but they are not regularly considered valence electrons.
What is the valence electron configuration for calcium atom?
calcium has the complete electronic configuration: 2, 8, 8 2 and hence has 2 valence electrons.
