Beryllium has the smallest atomic radius among the alkali earth metals.
A smaller atomic radius for beryllium would result from an increased positive charge in its nucleus, leading to a stronger attraction between the nucleus and the valence electrons. This increased attraction pulls the electron cloud closer to the nucleus, resulting in a smaller atomic radius.
Atoms with the largest atomic radius will be found in the lower left corner of the periodic table, specifically in the alkali metals and the alkaline earth metals groups. This is because these elements have the fewest protons in their nucleus relative to their electron cloud, resulting in a larger atomic size.
Copper (Cu) has a larger atomic radius than chlorine gas (Cl2). This is because atomic radius generally increases as you move down a group in the periodic table, and copper is located in a lower group compared to chlorine.
Not necessarily. The atomic radius of an element is determined by the size of the atom's electron cloud. While atoms of the same element would typically have the same atomic radius, atoms of different elements can vary in size due to differences in their electron configurations and the number of protons in their nuclei.
This element is tellurium with a covalent atomic radius of 140 pm.
Cesium has a larger atomic radius than rubidium. This is because as you move down a group in the periodic table, the atomic radius generally increases due to the addition of more energy levels and electrons.
Beryllium has the smallest atomic radius among the alkali earth metals.
The rounded atomic mass of oxygen is 16.00 amu (atomic mass units).
Carbon can either have a +4 or a -4 charge because it has four electrons in it's outermost electron level. It would be the same for it to take or remove electrons. This is very rare though, Carbon would most likely share electrons.
The atomic radius of helium is about 31 picometers (pm).
228, and um...... enrich said that the chart showed the atomic radius, and if Bromine's atomic radius is 114, then if I added together, then it would be 228
The atomic radius of selenium can be estimated to be approximately between 116 pm and 118 pm based on the trends in atomic radii going down a group in the periodic table. This is because atomic radius generally increases as you move down a group, so selenium's atomic radius would be smaller than arsenic's and germanium's.
Based on the bond length of 2.81 Å for bismuth triiodide, we can estimate the atomic radius of bismuth. Typically, the atomic radius is about half the bond length, so the estimated atomic radius for bismuth in this compound would be approximately 1.405 Å.

pm means picometer, one picometer is 1 x 10-12m so the radius of O in meters would be 74 x 10-12m, or 7.4 x 10-11m
