Note: All measurements given are in picometers (pm). For more recent data on covalent radii see Covalent radius. Just as atomic units are given in terms of the atomic mass unit (approximately the proton mass), the physically appropriate unit of length here is the Bohr radius, which is the radius of a hydrogen atom. The Bohr radius is consequently known as the "atomic unit of length". It is often denoted by a0 and is approximately 53 pm. Hence, the values of atomic radii given her… Webb30 seconds. Report question. Q. Elements Z and X are compared. Element Z is larger than Element X. Based on this you could say: answer choices. Element Z is further to the left side of the periodic table. Element X is closer to the top of the periodic table. Element Z and X are probably in the same group. A and/or B.
WebbAnswer (1 of 3): Every proton has a pull on each electron. So each electron has 18 protons pulling it towards the nucleus in the argon atom. Chlorine has 17 protons doing the same in the Chlorine atom. Sodium has the least pull or attraction to its electrons with 11 protons. The greater the pull ... Webb11 maj 2024 · Helium. Explanation: Helium has the smallest atomic radius. This is due to trends in the periodic table, and the effective nuclear charge that holds the valence electrons close to the nucleus. Atomic radius decreases as you move across a period from left to right and decreases as you move up a group from bottom to top.
Webb2 okt. 2024 · Whenever an electron shell is filled, adding another electron will cause a step-change in the atomic radius as can be seen in the jagged graph in one of the answers above. Helium turns out to be the smallest atom on that graph, which is one of the reasons it was discovered in the sun before it was discovered on earth. Share.
