Does Period 3 elements all have six 3p electrons?

Period 3 elements all have six 3p electrons. Period 4 elements have an inner electron configuration of [Ar]. The valence electrons of group 5A elements are in the 6s subshell. Group 8A elements have full outer principal s and p subshells.

What element has 6 valence electrons in period 3?

Sulfur
This puts Sulfur in the third period, with electrons in the p block and a total of 6 valance electrons.

What element is in Group 3 Period 3?

Group 3A. Group 3A (or IIIA) of the periodic table includes the metalloid boron (B), as well as the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). Boron forms mostly covalent bonds, while the other elements in Group 3A form mostly ionic bonds.

How many electrons do Period 3 elements have?

8 electrons
In the periodic table, there are 2 electrons in period 1, while both periods 2 and 3 have 8 electrons in the filled level. For atoms with atomic numbers less than about 20, the octet rule of electron addition and orbital filling applies.

Are there any period 3 elements with 2 electrons?

No period 3 element has electrons in the 4th shell. Group 2a elements all have an electron arrangement ending in 2 so have 2 electrons in their highest subshell (the s orbital). But this can be n=2, n=3 etc Xenon is at the end of P5 so can elements before Xe in period 5 have competely filled outer principle shells.

Which is the electronic configuration of period 3?

Note that the electronic configuration of all period 3 elements begins the same, 1s 2 2s 2 2p 6 , which is the electronic configuration of neon, so we use this, [Ne], to write a shorthand version of the electronic configuration, the condensed electronic configuration, of each period 3 element: Do you understand this?

What are the elements in the third period?

The third period contains eight elements: sodium, magnesium, aluminium, silicon, phosphorus, sulfur, chlorine, and argon. The first two, sodium and magnesium, are members of the s-block of the periodic table, while the others are members of the p-block.

How is the energy level of period 2 represented?

Because all the period 2 elements have the first energy level (K shell) filled, Chemists often used a short-hand notation to indicate this in which the electron configuration of the filled energy level is represented by the symbol of its Noble Gas in square brackets [].
