Oops, my mistake. I apologize for the error. The correct answer is carbon (C), which has six valence electrons. Thank you for pointing that out.
explain youre mistake and why carbon is right
I apologize for the confusion. In my initial response, I mistakenly listed phosphorus as an option twice, which was incorrect.
Now let me explain why carbon (C) is the correct answer. Carbon is located in group 14 of the periodic table. Group 14 elements, also known as the carbon group, have six valence electrons. The number of valence electrons is determined by the group number of the element. Since carbon is in group 14, it has six valence electrons. These valence electrons determine the chemical behavior and properties of the element when it forms chemical bonds with other elements.
thank you
You're welcome! If you have any more questions, feel free to ask.
Arthur writes the equation a=10b−7. He wants to rewrite it in terms of b. In Arthur’s first step, what value should he add to both sides of the equation?
In the equation a = 10b - 7, to rewrite it in terms of "b," Arthur needs to isolate "b" on one side of the equation. To do that, he should first add 7 to both sides of the equation. This step will help him eliminate the -7 term on the right side and bring it to the left side of the equation.
So, after adding 7 to both sides, the equation becomes:
a + 7 = 10b
