Identify the following statements as true or false. If false correct the existing statement. a) An increase in atomic number means an increase in both protons and electrons. b) Adding additional protons to an atom results in an increase in atomic size. c) Additional layers of electrons tend to make the atom larger. d) Electrons in the same shell are unable to shield each other from nuclear charge.

**Graph Explanation:**
The graph displays the relationship between atomic number (x-axis) and two components: atomic radius (measured in pm, represented by a red line) and effective nuclear charge (Z_eff, represented by a blue line). The graph covers elements from Sodium (Na) with an atomic number of 11, to Argon (Ar) with an atomic number of 18. As the atomic number increases from left to right, the atomic radius tends to decrease while the effective nuclear charge tends to increase.
**Question:**
- What conclusions can you draw from this graph?
### Statements for Evaluation
Evaluate the following statements as true or false. If false, provide a correction.
a) An increase in atomic number means an increase in both protons and electrons.
b) Adding additional protons to an atom results in an increase in atomic size.
c) Additional layers of electrons tend to make the atom larger.
d) Electrons in the same shell are unable to shield each other from nuclear charge.
### Ordering Task
Order the following elements in descending order (largest to smallest) according to size and explain your reasoning:
- Cs, Na, Mg, P, S, Cl
