Question

Element Rand Element Q have the same number of valence

electrons. These elements both have similar chemical behavior, but
Element R has fewer energy levels than Element Q. Which statement best
describes the positions of the two elements in the periodic table?

Answer 1

Elements R and Q have similar chemical behavior because they have the same number of valence electrons. Element R has fewer energy levels than Element Q. Elements in the same column of the periodic table have similar chemistry.

Step-by-step explanation:

The elements R and Q have similar chemical behavior because they have the same number of valence electrons. Valence electrons are the electrons in the outermost energy level of an atom and are responsible for determining an element's chemical properties. In this case, both R and Q have the same number of valence electrons. However, Element R has fewer energy levels than Element Q. This means that Element R is located in a lower period or row on the periodic table compared to Element Q. Elements in the same column of the periodic table have similar chemistry because they have the same valence shell electron configuration.

Answer 2

I know I'm answering super late, but I just want to help others who don't know the answer

Answer:

H. The two elements are in the same group, with Element R just above Element Q.

Step-by-step explanation:

When answering a question like this, I would highly recommended using a periodic table. I used a periodic table to find the answer to the question.
