1.Understanding the Question: The question asks about the significance of the number of electrons in the outermost shell of an atom. We need to determine whether this number relates to the "group" or "period" of the periodic table.
An atom s formal charge is the difference between the number of valence electrons in an isolated atom and the number of electrons assigned to that atom in a Lewis structure.
What is the maximum number of electrons in an atom that can have the following set of quantum numbers? n = 3, l = 2, m_l = -2 What is the maximum number of electrons that can occupy an orbital labeled dx^2-y^2? What is the maximum number of electro...
All the classical theoretical things that one can think of will only make it worse. The fact is that there are electrons in each atom, and we know from their spectra that there are internal motions; each of the electrons should have at least \frac{1}{2}kT of kinetic energy, and ...
The number of protons in an atom equals the number ofelectrons. This is necessary to balance the charge of an atom, and to increase its stability... Learn more about this topic: Atom | Definition, Composition & Examples from Chapter 2/ Lesson 1 267...
