Help please. 4. Two unknown elements react to a form a single compound. Element 1 is shiny, malleable, and conductive. Element 2 is a non-conductive gas. When they react, what would you expect to be true about the compound produced? (AKS 2a DOK 3)

a. The compound will probably have properties of both elements like a metalloid.

b. The compound will probably have high boiling points and melting points and will be conductive in solution.

c. The compound will probably have low boiling and melting points and will not be conductive in solution.

d. The compound will probably have high boiling and melting points and will not be

i think its A but i may be wrong

Explanation:

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

i think slash and
