Question

Which elements would react most easily with each other? (1 point)

an element with a high electronegativity and an element with a full shell of electrons

an element with a high electronegativity and an element with a single valence electron

an element with a high electronegativity and a second element with a high electronegativity

an element with a high electronegativity and an element with low reactivity

Answer 1

Answer:  an element with a high electronegativity and an element with a single valence electron  

is the correct answer

Answer 2

_______________________________________________________

Answer:

"Any element with a high electronegativity and an element with a single valence electron would react very easily on contact with each other."

"Why?"

For instance, fluorine is the most reactive non-metal element on the periodic table. Due to it's small size, as well as it's strong electronegativity, fluorine has a strong tendency to accept electrons from other atoms and ions. But when Fluorine comes in contact with Hydrogen (a single valence electron element), for instance, it immediately reacts, resulting in an explosion.
