3. compare reactivity between hydrogen (h), carbon (c), and nitrogen (n). which is most reactive and why? - which of these are in the same period on the periodic table?

3. compare reactivity between hydrogen (h), carbon (c), and nitrogen (n). which is most reactive and why? - which of these are in the same period on the periodic table?

Answer

Brief Explanations:

Hydrogen, carbon, and nitrogen are in the same period (period 2) on the periodic table. Reactivity is related to the number of valence - electrons. Hydrogen has 1 valence electron, carbon has 4, and nitrogen has 5. Hydrogen is more reactive as it only needs 1 more electron to achieve a stable configuration (duet for hydrogen), while carbon and nitrogen need more electrons to complete their octets.

Answer:

Hydrogen, carbon, and nitrogen are in the same period. Hydrogen is the most reactive among them because it needs only 1 electron to achieve a stable electron configuration.
