The atomic radius of aluminum is approximately 143 picometers (pm).
The element with the larger atomic number is likely to have a smaller atomic radius than the other element. This is because as you move across a period from left to right, the atomic radius generally decreases due to increasing effective nuclear charge pulling the electrons closer to the nucleus.
Please tell me your atomicnumber.You just did 'use atomic number in a sentence' by putting this question on-screen.You could even read the above question and answers aloud, and you will have done it again.I just couldn't believe my eyes when I realized that an atomic number is revealed by the number of protons in the nucleus of an atom!"What is your atomic number?" is NOT a good pick-up line, unless you are speaking to a scientifically-minded person.The atomic number of Helium is 2."The atomic number of Sulfur is 16."(Note that atomic number means the number of protons in the atom, that's why the term proton number is interchangeable with atomic number.)See the related Wikipedia link listed below for more information:
The element can always be identified by its atomic number, which is the number of protons in the nucleus of its atoms. Each element has a unique atomic number that distinguishes it from other elements in the periodic table.
It is helium that has the smallest atomic radius. Use the link below to see a list of elements arranged by atomic radius.
Fluorine
It is hydrogen.
Helium has the smallest atomic radius of any element, due to its low atomic number and size.
Atomic Radius gets greater down the periodic table and gets smaller to the right in the periodic table. This means, in order of atomic radius, that the five smallest elements are Helium, Neon, Fluorine, Oxygen, and Hydrogen in that order.

Fluorine has the smallest atomic radius among fluorine, chlorine, bromine, iodine, and astatine.
The answer choices for this question wasn't provided. Oxygen has the smallest atomic radius. The higher the electronegativity in an element makes the atomic radius smaller.
Tellurium has a larger atomic radius than phosphorus.
The element in period 4 with the smallest atomic radius is argon. It has a smaller atomic radius compared to the other elements in period 4 because it is a noble gas with a full valence shell, resulting in a small atomic size.
Atomic radius increases going down the periodic table and going from right to left, meaning that Fr (Francium) has the largest atomic radius and He (Helium) has the smallest. Therefore, Cl<S<P<Si<Al So the answer is Cl
The period 4 element with the smallest atomic radius is chlorine, which has a greater number of protons in the nucleus pulling the electrons closer, making it smaller compared to other elements in the same period.
Francium. The elements of the lower left hand side of the periodic table have the largest atomic radius. The upper right has the smallest.
