In a sublevel for which l = 1, there is/are orbital(s), and the maximum number of electrons that can be accommodated is. How many valence electrons are in an atom of magnesium? Identify the group of the periodic
Name an element in the fourth period (row) of the periodic table with the following: a. five valence electrons b. four 4p electrons c. three 3d electrons d. full s and p sublevels. Identify the element that has an atomic number of 40. a. zirconium b. neon c. calcium d. bromine ...
Ionic compound: The ionic compounds are formed when a cation and anion(opposite charges) combine together. The cation is formed when the electrons are lost by an element and the anions are formed when the element gains the electrons. The transfer of the...
Decide if the compound/ion listed can satisfy the octet rule (duet rule for H), If the compound/ion cannot satisfy the octet rule for one of the atoms in the formula, choose one of the following three reasons why; ...
Metals, such as aluminum have high thermal and electrical conductivity, whereas non-metals, such as sulfur are insulators. Answer and Explanation: a). Fluorine. Fluorine is a halogen. It contains seven outermost electrons; thus, it prefers to...
