Which statement about hydrogen bonds is true?
athey are the only force that allows a gecko to climb up glass.
bthey are the weakest of the intermolecular forces.
cthey are much stronger than intramolecular forces.
dthey water striders walk on water by creating surface tension.

explanation: well the force of an object when it lands sitting on the ground isthe force of a wide rage of situations crucial to physics? ; ( i 'm trying my best to alot but im not smart enofe you for giving me this chance though! 3(

- 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
