WILL GIVE BRAINLIEST TO CORRECT AWNSER Sodium (Na) and iodine gas (I2) react to form sodium iodine (NaI). Which equation is a correct representation of the balanced equation? 2Na+I2→2NaI I2→2NaI+2Na NaI→2Na+I2 Na→NaI+I2

12+Na  is a correct representation of the balanced equation

- 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
