Electronic Configuration of Elements: The ground-state electronic configuration of an element is the distribution of its electrons into the shells, subshell, and orbitals in the increasing order of energies in the lowest energy of the atom.
When we go down a group, the number of valence electrons remains the same, although the number of shells increases. While valence electrons across a period incrementally climb by one, the number of shells remain the same. The period number (row number, to remind you) in which an elem...
How to Find the Period of an Element? The value of n for the outermost or valence shell is shown by the period. The number of shells in an atom determines the period. The period of an element is represented by the principal quantum number (n) of the valence electrons in the electronic...
The first and second electron shells of an element are filled and there are two electrons in the third electron shell. What is the atomic number for this element? How many valence electrons does the element In have, and what are the specific ...
What is an Electron? An electron is a negatively charged subatomic particle that orbits the nucleus of an atom. The nucleus consists of positively charged protons and neutrally charged neutrons. The number of protons in the nucleus defines the atomic number of an element, and the number of el...
Electron configurations are written so as to clearly display the number of electrons in the atom as well as the number of electrons in each orbital. Each orbital
To determine the valence electrons in an atom, you write the electron configuration of the element in noble-gas-inner-core form. The electrons outside...Become a member and unlock all Study Answers Try it risk-free for 30 days Try it risk-free Ask a question Our experts can answer ...
Atoms have a desire to lose or gain an electron in order to be stable. Once they've either gained or lost some electrons, they have charge associated with them since their electron and proton numbers no longer balance out. But what determines what happens to the electrons an atom has? It...
How electron microscopes workIf you've ever used an ordinary microscope, you'll know the basic idea is simple. There's a light at the bottom that shines upward through a thin slice of the specimen. You look through an eyepiece and a powerful lens to see a considerably magnified image of...
1. The electronic configuration refers to the arrangement of electrons in the many shells, subshells, and orbitals that make up an element's atom. 2... Learn more about this topic: Valence Electrons | Definition, Role & Examples from Chapter...
