Which element has 3 energy levels and 5 valence electrons?
The element that has three energy levels and five valence electrons in its outer level is phophorous, atomic number 15. What element has 5 valence electrons and 6 energy levels? What element has 5 electron shells and 6 valence electrons? Does PB have 5 valence electrons?
How many valence electrons does phosphorus have in the periodic table?
Group 1 elements have one valence election, Group 2 elements have two, Group 13 (also known as IIIA) have three, Group 14 (IVA) have four, Group 15 (VA) have five and so on. Phosphorous is the 5th element from the left in the third period so it has five valence electrons.
How many electron energy levels are there in the 3rd period?
All elements in the third period have three electron energy levels and have their valence electrons in the third level. Orbitals are sub-levels within the principal energy level, so the word orbital isn't used interchangeably with energy level.
What is the principal energy level of the periodic table?
Each row or period of the periodic table corresponds to a principal energy level. All elements in the third period have three electron energy levels and have their valence electrons in the third level. Orbitals are sub-levels within the principal energy level, so the word orbital isn't used interchangeably with energy level.

What element has 5 valence electrons and 3 shells?
A neutral phosphorus atom has 15 total electrons. Two electrons can go into first shell, eight in the second shell, and it has five more in the third shell. The third shell is the outer valence shell, so it has 5 valence electrons.
What elements has 5 valence electron?
Elements having 5 valence electrons are placed in Group 15. The elements of group 15 are nitrogen, phosphorus, arsenic and antimony.

What is the valency of group 5 elements?
Group 5 elements, however, have 5 valence electrons and will tend to take 3 electrons and so have a valency of -3.
How many covalent bonds are formed with 5 valence electrons?
three covalent bondsGroup 5A (15) elements such as nitrogen have five valence electrons in the atomic Lewis symbol: one lone pair and three unpaired electrons. To obtain an octet, these atoms form three covalent bonds, as in NH3 (ammonia).
