Helium would have - it is an alpha particle.
Among potassium (K), oxygen (O), sulfur (S), and lithium (Li), lithium would have the smallest ionic radius. This is because lithium has the highest effective nuclear charge, resulting in a stronger pull on its outermost electrons, leading to a smaller ionic radius.
The list from smallest to largest ionic radius would be: Be2+, Mg2+, Ba2+, Ra2+. Beryllium and magnesium ions have smaller ionic radii due to their higher charge and stronger attractive forces compared to barium and radium ions.
The alkali earth metal with the smallest atomic radius would be beryllium(Be), number four
The smallest radius from I Br Br I would be the bromine atom since it is closer to the central iodine atom compared to the outer iodine atom.
Neutral atoms are smaller than negatively charged ions of the same element.Bromine is smaller than iodine.So neutral bromine would have the smallest radius of the species listed.
I would not think so as their natural state radius is so close. Ca(2+) loses two electrons, so I think it would have the smaller ionic radius.
No, "ne2" is not an ionic compound. "Ne2" would represent a molecule of two neon atoms bonded together covalently, since neon is a noble gas and does not typically form ionic bonds.
No, it would not, because the smallest possible radius for a spherical celestial body is 200 km (124 miles) and Mercury would only have a radius of 61 miles (98 km) if it was shrunk 96%.
For an element, it would be an atom. For a molecular substance, it would be a molecule. If it is an ionic compound, it would be a formula unit.
