Question

11 The atoms of a certain element each contain 7 protons and 5 valence electrons. Which statement correctly identifies this element and describes its chemical reactivity Total Points (____/10) A) The element is Lithium (Li), and it is highly reactive B) The element is Nitrogen (N), and it is highly reactive C) The element is Lithium (Li), and it is not very reactive D) The element is Nitrogen (N), and it is not very reactive

Answer 1

D) The element is Nitrogen (N), and it is not very reactive

Step-by-step explanation:

Given that the atomic number or proton number of Nitrogen, hence it can be concluded that the statement correctly identifies NITROGEN.

Also, considering that the quantity of electrons in the outermost shell of an atom specifies its reactivity, and the higher the number of electrons or electron shells, the lower the level of reactions because they are less likely to gain an electron.

Hence, it can also be concluded that with 5 valence electrons, Nitrogen is not very active
