Bromine has more protons in the nucleus. This results in bromine atoms being heavier than chlorine, and therefore more mass in a certain area (which is more density).

What does the arrangement of the periodic table tell scientists
BlackZzzverrR [31]

Answer:

The arrangement of the periodic table leads us to visualize certain trends among the atoms.

Elements are arranged from left to right and top to bottom in order of increasing atomic number.

The vertical columns (groups) of the periodic table are arranged so that all its elements have the same number of valence electrons (outer ring). All elements within a certain group share similar properties.

The rows are called periods. All elements in a row have the same number of electron shells.

What is the difference between mass and weight?
Olin [163]

Explanation:

The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.
