select the correct boxes. which two elements have the same number of valence electrons?\n| element | atomic number |\n| ---- | ---- |\n| barium | 56 |\n| neon | 10 |\n| silicon | 14 |\n| carbon | 6 |
Answer
# Explanation:
## Step1: Determine valence - electrons of barium
Barium has atomic number 56. It is in Group 2 of the periodic table, so it has 2 valence electrons.
## Step2: Determine valence - electrons of neon
Neon has atomic number 10. It is a noble gas in Group 18, so it has 8 valence electrons.
## Step3: Determine valence - electrons of silicon
Silicon has atomic number 14. It is in Group 14, so it has 4 valence electrons.
## Step4: Determine valence - electrons of carbon
Carbon has atomic number 6. It is in Group 14, so it has 4 valence electrons.
# Answer:
Silicon, Carbon
