select the correct boxes. which two elements have the same number of valence electrons? element atomic number barium 56 neon 10 silicon 14 carbon 6

Answer

Explanation:

Step1: Determine valence - electrons of barium

Barium (atomic number 56) is in Group 2 of the periodic table. Elements in Group 2 have 2 valence electrons.

Step2: Determine valence - electrons of neon

Neon (atomic number 10) is a noble gas in Group 18. It has 8 valence electrons.

Step3: Determine valence - electrons of silicon

Silicon (atomic number 14) is in Group 14. Elements in Group 14 have 4 valence electrons.

Step4: Determine valence - electrons of carbon

Carbon (atomic number 6) is also in Group 14. Elements in Group 14 have 4 valence electrons.

Answer:

Silicon, Carbon
