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.
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.
The element in question is magnesium. It has 12 protons (more than sodium and less than argon), 2 more valence electrons than oxygen (which has 6), and 8 fewer valence electrons than neon (which has a full valence shell with 8 electrons).
