hydrogen reacts with an element to form a compound. which element would have the most valence electrons available to react with hydrogen?\noxygen\nchlorine\nneon\nnitrogen
Answer
Explanation:
Step1: Determine valence - electrons of oxygen
Oxygen is in group 16 of the periodic table. It has 6 valence electrons.
Step2: Determine valence - electrons of chlorine
Chlorine is in group 17 of the periodic table. It has 7 valence electrons.
Step3: Determine valence - electrons of neon
Neon is a noble gas in group 18. It has 8 valence electrons, but it is very stable and has a very low reactivity, so it does not readily react with hydrogen.
Step4: Determine valence - electrons of nitrogen
Nitrogen is in group 15 of the periodic table. It has 5 valence electrons.
Step5: Compare valence - electrons
Among oxygen (6 valence electrons), chlorine (7 valence electrons), neon (unreactive 8 - valence electrons), and nitrogen (5 valence electrons), chlorine has the most reactive valence electrons available to react with hydrogen.
Answer:
chlorine
