Convert 2.072x10^43 atoms element to moles

Given :

Number of atoms of an element, n = 2.072 × 10⁴³ atoms.

To Find :

Number of moles of that element in given number of atoms.

Solution :

We know, 1 mole of any element contains 6.022 × 10²³ atoms.

So, number of moles in given number of atoms are :

Hence, this is the required solution.

- 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
