Please help me!
Sure! I can help you with that.
The valence electrons are the electrons that participate in chemical bonding. To determine the valence electrons of an element, you can look at the group number of the element in the periodic table. In the case of sulfur (S), it is located in group 16, so it has 6 valence electrons.
Now, let's move on to your next question - the needed electrons. This refers to the number of electrons an element needs to achieve a stable electron configuration, typically the octet rule for nonmetals. Sulfur has 6 valence electrons, and it needs 2 more electrons to complete its octet.
To determine the difference in electrons or the bond formed, you can subtract the number of valence electrons from the number of needed electrons for the element. In this case, the difference is 2, which means sulfur will form a bond by sharing two electrons with another element.
To summarize:
- Valence e- of sulfur (S): 6
- Needed e- for sulfur (S): 8
- Difference/Bond: 8 - 6 = 2
I hope this helps! Let me know if you have any further questions.
