Question

he atoms of a certain element each contain 10 protons and 8 valence electrons. Which statement correctly identifies this element and describes its chemical reactivity?

F The element is neon, and it is highly reactive.
G The element is fluorine, and it is not reactive.
H The element is neon, and it is not reactive.
J The element is fluorine, and it is highly reactive

Answer 1

Im pretty sure the answer is H. If an element has 8 valence electrons, then it has no room for anymore and is stable, meaning that it would no reaction. Fluorine does not have 8 valence electrons.
