use the periodic table to answer the question. a student constructed three models of atoms using information gathered from the periodic table. part b based on the models, which statement best describes how the elements shown are organized on the periodic table? a the number of protons in an atom increases from right to left. b the number of protons in an atom increases from left to right. c elements with a greater atomic mass are located above elements with less atomic mass. d elements with a greater atomic mass are located to the left of elements with less atomic mass.

use the periodic table to answer the question. a student constructed three models of atoms using information gathered from the periodic table. part b based on the models, which statement best describes how the elements shown are organized on the periodic table? a the number of protons in an atom increases from right to left. b the number of protons in an atom increases from left to right. c elements with a greater atomic mass are located above elements with less atomic mass. d elements with a greater atomic mass are located to the left of elements with less atomic mass.

Answer

Answer:

B. The number of protons in an atom increases from left to right.

Explanation:

Step1: Recall periodic - table trends

Elements in the periodic table are arranged in order of increasing atomic number. The atomic number is equal to the number of protons in an atom.

Step2: Analyze option A

The number of protons does not increase from right - to - left. This is incorrect.

Step3: Analyze option B

As we move from left to right across a period in the periodic table, the atomic number (number of protons) increases. This is correct.

Step4: Analyze option C

Atomic mass does not follow a simple "above - below" relationship in the periodic table. There are many factors affecting atomic mass and its position in the table. This is incorrect.

Step5: Analyze option D

There is no such left - right relationship based on atomic mass in the periodic table. This is incorrect.
