To determine the number of valence electrons present in noble gases, we can follow these steps:Step 1: Identify Noble Gases Noble gases are the elements found in Group 18 of the periodic table. The noble gases include: - Helium
Ionic Bonding:Atoms transfer valence electrons to achieve stability. For example, in sodium chloride (NaCl), sodium donates one electron to chlorine, resulting in positively charged sodium ions (Na⁺) and negatively charged chloride ions (Cl⁻) that attract each other. Importance of Valence Ele...
Elements are most stable when they have all eight valence electrons. This is called the octet rule. The only elements that have this electron configuration are the noble gases, thereby they are inert. All other elements gain, lose or share electrons in order to achieve a full set of valence...
Valence electrons are theelectronsof anatomwhich are situated at the highest energy level (in the Bohr model: outermost shell of the atom). If this highest energy level is not fully occupied, which is the case with noble gases, the valence electrons are available for generating molecule formatio...
An atom is reactive or inert depending on how many valence electrons it has. The most reactive atoms are those that have one or two to lose or those that have one or two to gain in order to maintain stability. For this reason, the noble gases— all of which have a closed outer shell...

If you look closely, only a limited range of element in the periodic table would want to either gain electrons or loose electrons to gain the equivalent noble gas structure. Once you get into elements with the 3d orbitals (the transition metals), your 8-electron rule is no longer valid!
and discuss which students answered and why, or “Noble gases - how many electrons do you need to fill your outermost shell?” This easy way to teach about valence electrons will help students connect the concept of electrons to the periodic table. Like other chemistry activities, these ...
How many valence electrons do the noble gases have? a. 1 b. 2 c. 8 d. 10 How many valence electrons does the element with atomic number 117 have, and what are the specific valence electrons for Z=117? How many valence electrons are there in chlorine and what is its valency?
What is the total number of valence-shell electrons around the central xenon atom in the molecule XeF2? Valence Electrons: Valence electrons are the electrons found in the outermost shell, in contrast to core electrons which are present in the inner shell. Beca...
