The answer is 4s, because it is in the 4rth period of the Periodic Table of Elements =]
There are 3 electrons in the highest occupied energy level of aluminium.
3s electrons and 1 p electron.
Copper has two electrons in its outermost shell and less than eight in the valence shell.
2
4
It has 5 electrons in its outermost shell.
The outer shell (N=4) of the copper element has 2 electrons.
The electrons on the outermost shell of an atom tell you how many valence electrons an atom on the periodic table has , and this number can be used to apply to the octect rule .
3
the valence shell is the outermost shell of an atom that has free electrons for taking part in chemical reactions... the valence shell of sodium has one free electron
thallium has 3 electrons in outermost shell.
There are 2 electrons on the outermost shell of calcium.
Sulphur has 6 electrons in its outermost shell.
It has 5 electrons in its outermost shell.
6 electrons.
2 electrons.
There is no Iodone atom, there is however an Iodine atom that has seven valence electrons or seven electrons in outermost shell.
Magnesium has two electrons in its outermost shell.
2 electrons in the only shell helium has.
only 2 electrons.
7 electrons
