Question

1. In cement, when silicate anions join, the molecule forms or "condenses out" as a result? What is it?

2. Carbons love to share electrons and almost exclusively forms covalent bonds with other atoms. why?

3. "Cement" and "concrete" are not identical but they are related, which is why they tend to get used interchangeably. How do they differ?

4. In general terms, what happens to monomers during the process of polymerization?

Answer 1

2:- the atomic number of carbon is 6.Its electronic configuration is (2,4),that means it has two electrons in it's first k she'll and four electrons in it's second L shell.

Like every other atom carbon also tries to complete it's octate .,but the problem with carbon is that,it has to either gain four electrons or loose four electrons .when it will gain four electrons,it will aquire four negative charges and becomes C-4,and when it losses four electrons it will aquire 4 positive charges.In these both cases carbon becomes very unstable,and these two forms requires much energy.

Thus as a result carbon completes it's octate by sharing electrons with other atoms ,forming covalent bonds
