The ionic compound, MClx (where M is a metal and Cl is chlorine) has a formula mass of 190 g/mol and a mass percent of chlorine of 74.8%. What is the atomic mass of the element

To calculate percent by mass, use the equation below: calculate the percent by mass of each element. %n = % %h = % %o = %

Which is a characteristic of the electron sea model for metallic bonding? molecular orbitals overlap to produce bands. electrons flow easily between metal nuclei. electrons are in fixed positions in the orbitals. atomic nuclei are arranged in an irregular pattern.

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent
