What is the number of electrons in the "p" sublevel in the outermost electron shell of Group IVA elements?
- pisgahchemistLv 71 decade agoFavorite Answer
The elements in group IVA have 2 electrons in the p-sublevel.
There is one electron in each of two of the three orbitals. The third orbital is empty. Not only is there one electron in each orbital, but both electrons have the same spin. Hund's rule.

The elements in Group IVa are: Ti, Zr, Hf, and Th.
Their electron configurations (in the order filled) are:
Ti: [Ne] 3s2 3p6 4s2 3d2
Zr: [Ar] 4s2 3d10 4p6 5s2 4d2
Hf: [Kr] 5s2 4d10 5p6 6s2 4f14 5d2
Th: [Xe] 6s2 4f14 5d10 6p6 7s2 6d2
(Note that I used the noble gas configuration of the noble gas two periods prior to the element of interest. I did this to show the p orbitals.)
In every case, you can see that the outermost "p" sublevel that is filled contains 6 electrons.
However, you may also notice that the outermost "s" sublevel has a principal quantum number (or shell) that is one higher. So, if you are simply looking at the highest shell number, there are zero electrons in the "p" sublevel because it hasn't been filled yet.
See this website for a good illustration of the order in which the shells and orbitals are filled:

solutions are much less high priced, yet strategies of determining the respond are effective. to discover the style of valence electrons in an atom of a definite element, you may desire to seek for suggestion from the periodic table. despite if the counsel does not inform you without delay what number electrons there are in the valence shell of an atom, you may desire to undergo in recommendations that factors are arranged in columns (communities) in accordance to the style of valence electrons. team one million factors, as an occasion, have only one valence electron. team 2 factors have 2 valence electrons. communities 3 via 12 variety between one and 2 because of the fact they're transition factors. team 13 factors have 3 valence electrons. team 14 factors have 4 valence electrons. team 15 factors have 5 valence electrons. team sixteen factors have six valence electrons. team 17 factors have 17 valence electrons, and team 18 factors (noble gases) have in maximum situations 8 valence electrons apart from helium that only has 2. Going back on your question, you may desire to learn the situation of each and every of the above factors in the periodic table and are available up with the likely answer. a. sodium - atomic style eleven - present day in team one million - one valence electron b. lithium - atomic style 3 - present day in team one million - one valence electron c. copper - atomic style 29 - present day in team eleven - transition element - one valence electron (despite in case you may no longer discover this counsel on the periodic table, undergo in recommendations that transition factors could have one or 2 valence electrons.) d. fluorine - atomic style 9 - present day in team 17 - seven valence electrons e. sulfur - atomic style sixteen - present day in team sixteen - six valence electrons answer: The element with the main important style of electrons in the outermost shell is "d. fluorine".
