What is the best way to memorize the periodic table

- breaking it down into sections

-learn the element song

-use colors to learn the element groups

Explanation:

what also may help which is time-consuming is writing it out over and over if not I would prefer to learn the song it may seem childish a little but it will help in the long run.

I personally have a method for learning stuff like this.

Try going one at a time, and ever once in awhile. Like memorize the first element, then the one next to it [in whichever order you please]

Ex: memorizing 1-10

1.. 1,2.. 1,2,3.. 1,2,3,4..

And then repeat that row until you can recite it almost without hesitation, then move onto another line.

This works for both placement memorization and element name.

yes they ca   is ur ansswerrr

- 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
