The orbitals composing an atom's valence electron shell (a) are arranged as concentric spheres (b) contain the atom's least energetic electrons (c) may change shape when covalent bonds are formed (d) never contain more than 1 ...
Electrons have a charge of negative one and negligible mass. Valence electrons are electrons that are available for bonding with other elements. Part of the valence electrons of transition metals, like iron, are in the d shells, while the main group elements' valence electrons are in the s ...

Are cation atoms that have lost an electron positively charged How can one balance chemical equations with given oxidation numbers? How do you write a compound which contains calcium (Ca) and the polyatomic ion chlorate (ClO3)? Explain why a S2- ion is larger than a Cl- ion. What is an...
Classify each element as an alkali metal, alkaline earth metal, halogen, or noble gas. a. sodium b. iodine c. calcium d. barium e. krypton Why does chlorine have a higher electron affinity than fluorine? What is the number of valence electrons in aluminum?
We use two generalizations to compare the atomic radii of elements. The more determining factor is the number of electron shells: The greater the number the bigger the atomic radius. The second factor (which we often use to compare atoms of the same period) is that the greater the atomic ...
Covalent Bonding and Electron Shells: Definitions, Relationship & the Octet Rule from Chapter 1 / Lesson 6 41K Covalent bonding is when atoms share one or more electrons, and electrons orbit the nucleus of an atom in shells. Explore how electrons create energy shells, what the octet rule ...
The electrons contained in the shells nearest the nucleus carry less energy than the electrons in the outer shells. When certain atoms are exposed to ultraviolet (UV) light, a photon (particle of light energy) of UV will cause an electron residing in a lower-energy inner electron shell to ...
Classify each substance (I have to write which are elements and which are compounds). calcium, carbon dioxide, chalk, mercury, graphene, salt, sodium, sugar, water, zinc. How do you find a Becquerel in a radioactive element without a radiation meter?
