What element in the fourth period has 5 valence electrons? Therefore, the element in the fourth period of the periodic table which has five valence electrons is

Arsenic

.

Does carbon have 5 valence electrons?


Carbon has four valence electrons

and here a valence of four. Each hydrogen atom has one valence electron and is univalent.

Does nitrogen have 5 valence electrons?


Nitrogen has a total of 5 valence electrons

, so doubling that, we would have a total of 10 valence electrons with two nitrogen atoms. The octet requires an atom to have 8 total electrons in order to have a full valence shell, therefore it needs to have a triple bond.

Which element has 5 valence electrons in the second period?


Nitrogen

has 7 electrons — 2 in the first shell, and 5 in the second shell (so five valence electrons).

What element has 4 valence electrons and 5 electron shells?

Atomic Number Element Energy Levels or “shells” 4

Beryllium (Be)

2
5 Boron (B) 3 6 Carbon (C) 4 7 Nitrogen (N) 5

Going back to the periodic table we find

Arsenic (As)

in period 4 and Group 5A.

Atoms in the

nitrogen family

have 5 valence electrons. They tend to share electrons when they bond. Other elements in this family are phosphorus, arsenic, antimony, and bismuth.

Period 4 elements in the periodic table include the

18 chemical elements from atomic number 19 to 36

: potassium (K), calcium (Ca), scandium (Sc), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), gallium (Ga), germanium (Ge), arsenic (As), selenium …

A period 4 element is an element in

the fourth period (row)

of the periodic table. It begins at potassium and ends at krypton. Period 4 has 18 elements. Period 4 elements have electrons in the first four electron shells.

Now

Carbon has 5 electrons

. Because each Carbon atom has 5 electrons–1 single bond and 3 unpaired electrons–the two Carbons can share their unpaired electrons, forming a triple bond.

The elements of group 15 (column) VA of the periodic table all have electron configurations of s2p3 , giving them five valence electrons. These elements include

Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb) and Bismuth (Bi)

. [Ar]4s23d104p3 .


Iodine is the halogen element which is present in fifth period

while Br and Cl belongs to fourth and third period.

The Group 4A elements have

four

valence electrons in their highest-energy orbitals (ns

2

np

2

).

Let’s quickly look at the group 5A elements, which are located

towards the right side

of the periodic table. Group 5A includes Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb), and Bismuth (Bi). Sometimes group 5A is known as Group 15 or Group VA, it just depends on the periodic table you are viewing.


The highest-numbered shell is the third shell, which has 2 electrons in the 3s subshell and 3 electrons in the 3p subshell

. That gives a total of 5 electrons, so neutral phosphorus atoms have 5 valence electrons.

Magnesium is alkaline earth metal and belongs to group IIA of the periodic table. It has

two valence electrons

which are present in 3s subshell.

Atomic Number Element Energy Levels or “shells” 13 Aluminum (Al) 3 14 Silicon (Si) 4 15 Phosphorus (P) 5 16 Sulfur (S) 6
