Rank these elements in terms of decreasing atomic radius?
Y (biggest) Fe Ga S F (smallest)
What is the atomic radius of aluminum?
The atomic radius of aluminum is approximately 143 picometers (pm).
Given any two elements within a group is the element with the larger atomic number likely to have a larger or smaller atomic radius than the other element?
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.
How can you use the word atomic radius in a sentence?
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:
Any element can always be identified by its?
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.
