yes, oxygen has 8 electrons and uranium has 92 electrons
The alkali metal with 76 fewer electrons than francium is lithium. Francium has 87 electrons, so lithium, which has 3 electrons, has 76 fewer electrons than francium.
The boron atom has fewer electrons than the lithium atom. Lithium has 3 electrons in its neutral state, while boron has 5 electrons.
A boron atom has fewer electrons than a lithium atom. Lithium has 3 electrons while boron has 5 electrons.
Silicon has 4 fewer electrons than aluminium. Aluminium has 13 electrons, while silicon has 9.
The element described is chlorine. It has 7 valence electrons, which is more than oxygen but fewer than neon. Chlorine has 17 protons, more than sodium but fewer than argon.
The element that fits all these criteria is phosphorus (P). Phosphorus has 5 valence electrons, which is more than oxygen (6 valence electrons), fewer than neon (8 valence electrons), and has 15 protons, which is more than sodium (11 protons) but fewer than argon (18 protons).
Cl Chlorine
It would have fewer electrons. A cation is a positively charged ion which means that there are fewer negatively charged electrons than positively charged protons.
there is no such element
The element with 5 fewer electrons than sodium is not a gaseous element!
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.
This would be Sb - Antimony.
