Which statement identifies what happens when bonds are broken? a. the attraction between atoms increases, so they collide with another and destroy the bond. b. the attraction between compounds weakens, so they separate into different categories based on bond type. c. the attraction between simple compounds or elements increases, so they congregate and form mixtures. d. the attraction between atoms weakens, so they separate into elements or simpler compounds.

The attraction between atoms weakens, so they separate into elements or simpler compounds.

Explanation:

i took the test and got it correct

3 hours because it is a decent distance.

- 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
