Grayson wants to build an inexpensive shelter at his bus stop that he can stand in when it rains. What material would be best for building a shelter that is both strong and waterproof

There is a material called Asphalt fabric.

It is a black waterproofing fabric made with kraft paper substrate and impregnated with a mixture of asphalt and mineral oil.

Explanation:

The material does not serve alone.

They use it to cover any construction material.

The shelter at the bus stop can be constructed of any material that is strong and covered with this

In addition to that, the fabric is really cheap.

Wood can be used and covered with this fabric and it would be a cheap shelter, with a long and resistant life of use.

- 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
