How many valence electrons does the element Ca have, and what are the specific valence electrons for Ca? How many valence electrons does the element Br have? How many valence electrons do the noble gases have? a. 1 b. 2 c. 8 d. 10 How many valence electrons does a hydr...
The valence electrons are the electrons found in the outermost shell. This shell is usually unfilled for neutral atoms, with noble gases being the only exception.Answer and Explanation: The elements of the periodic table are grouped together in columns aptly called groups by certain propert...
Helium has two electrons in its only energy shell (K-shell). The other two elements have eight electrons in their valence shells. Since these are the maximum number of valence electrons which the atoms of these elements can have, therefore, they do not h
Step-by-Step Solution:1. Understanding Inert Gases: Inert gases, also known as noble gases, include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). They are located in Group 18 of
Unlike elements in groups 1A-3A, which can form cations, and atoms in groups 7A-5A, which can form anions, noble gases generally do neither. Using neon as a specific example, explain why this is so. What can be said about the ions of atoms in the s...

We have seen that Phosphorus has 15 total e- and 5 of them are valence e-. The Lewis dot structure for Phosphorus is: P The first 2 valence electrons are always paired up on top of the symbol (representing the filling of the s sub-level) then the other e- are place one at a tim...
