the table shows the types of elements that form two componds. which of the following statements is true about how the bonding occurred to create the two compounds

Electrons are shared in compound X and transferred in compound Y.

1. ionic bonding  

Bonding that occurs due to electron transfer. Can occur in metal and non-metal atoms. To get stability, atoms release or bind electrons to get stable electron regulation from noble gases  

2. covalent bonding  

Bonding that occurs due to shared use of electron pairs  

The two bound atoms contribute their electrons to produce bonds  

Generally occurs in non-metallic elements  

So compound X = covalent bond (metal with metal) and compound Y= ionic bond(metal with non metal)

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

it's c. elements are placed in rows based on how may valencies electrons have.
