One metal object is a cube with edges 3.00 cm and a mass of 140.4 g. A second is a sphere with a radius of 1.42 cm and a mass of 61.6 g. Are these objects made of the same metal?

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
