Answer:
Cl < P < Mg < Na
Explanation:
Cl must have the smallest radius because it is located to the right of the remaining elements on the same row. P must have the second smallest radius because it is located to the right of the remaining elements on the same row. Mg must have the Third smallest radius because it is located to the right of Na on the same row. Therefore, Na has the Largest radius.

Answer:
leading zeroes to the left of a decimal point. and trailing zeros to the left of an invisible decimal point.
Explanation:
- All nonzero digits are significant figures. Example: 713 has three significant figures. 18,991 has five significant figures.
- Zeros located between two nonzero digits are significant figures. Example: 505 has three significant figures. 17,009 has five significant figures.
- Zeros at the ends of numbers are only significant if there is a decimal point in the number. Example: 502.00 has five significant figures (5,0,2,0,0). 5020 has three significant figures (5,0,2) 100,000 has one significant figure (1)
- Zeros that come before the first nonzero digit are not significant. Example: 0.0007 has one significant figure (7). 0.0970 has three significant figures (9,7,0)
