On the periodic table, electronegativity increases as we move from the bottom to the top. what information does this give us?
a) bro mine is more likely than chlorine to form a chemical bond
b) hydrogen and neon are equally likely to form a chemical bond
c) fluorine is more likely than chlorine to form a chemical bond
d) lithium and hydrogen are equally likely to form a chemical bond

Option(c)

Fluorine is more likely than chlorine to form a chemical bond than chlorine;

Explanation:

When we move a step down in a group in periodic table, more electrons shells are added and more protons are also added, thereby increasing the atomic size (Z).

Here, in this case, the size of atoms of chlorine is greater than that of fluorine. As new shells are added, the ability of nucleus to attract electrons decreases, since distance between nucleus and outer shell increases, the electromagnetic force decreases. Therefore, it becomes harder for chlorine to form bond and is easier for fluorine to form a chemical bond.

Explanation:

Took the test :)

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
