Answer: An element's group number tells you how many valence electrons the element has.
Explanation:
In the periodic table, each element is placed in a specific location because of its atomic structure.
The elements are arranged in rows, called a period. All of the elements in a period have the same number of atomic orbitals.
The elements are also arranged in vertical columns. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. These electrons are called as valence electrons. Example: Group 1 elements have 1 valence electron each.
Answer:
Pressure and volume have an inverse relationship when temperature is constant. This is Boyle's Law.
