In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li). In fact, for the alkali metals (the elements in Group 1), the
To determine which of the following elements has the largest ionization energy among scandium, zinc, cadmium, and mercury, we can follow these steps:Step 1: Understand Ionization Energy Ionization energy is the energy required
Electronegativity: The electronegativity of an atom of an element is a measure of the force with which the atom pulls on the shared electrons in a covalent bond. The index is important to investigate the type of bond that exists between atoms of two elements: ...
