Points Two neutral objects (Object A and Object B) are rubbed together during the process of "charging by friction."
Object A ends up with a positive charge.
Which best describes what happened in this process?
O Object A has gained electrons, Object B has lost electrons
O Object A has lost electrons, Object B has gained electrons
O Object A and Object B both have gained electrons
O Object A and Object B both have lost electrons

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
