What is the name for the element in Period 4 and Group 2 (IIA) of the Periodic Table? a. Calcium b. Carbon c. Chlorine d. Cobalt What is the electron configuration of chlorine? What is the name of the Group of the Periodic Table in which all the elements have a valence shell elect...
Valency is the combining capacity of the elements to form compounds. During the formation of the molecules of the compounds, atoms combine in certain fixed proportions. Visit BYJUS to learn more about it.
The CaF2 Lewis structure is shown below: In the Lewis structure drawing of CaF2, the first step is to determine the valence electrons of the atoms. The valence electrons of calcium and fluorine are 2 and 7, respectively, and the electronegativity of fluorine atom is smaller than that of ...
What is the valency of chromium? Transition Metals: Located in the middle section of the periodic table, the transition metals are elements that often have more than one oxidation state and can combine with other elements in different ways to form different compounds. For example, iron can form...
and f. Each element has an atomic number, and it is the same number as the electrons. For example, fluorine has the atomic number of 9, which indicates it has 9 electrons. The electron configuration shows the energy levels, the number of electrons in each level, and the type of orbitals...
