Francium (Fr)
down a group, the radius increases.
Yes because Cs has more Electrons- which causes it to have more shells and this causes the structure to be larger. Li is small because it had a smaller amount of electrons- so it doesn't need a lot of shells which causes the shell to be smaller and the valence electron to be closer to the nucleus.
Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Francium (Fr) are classified as alkali metals. These elements are highly reactive, easily lose their outermost electron to form a positive ion, and are typically found in Group 1 of the periodic table.
No, H+ ions are the smallest (proton size), hydrogen atoms and even Li+ ions are smaller than Li atoms.
Group 1A in the periodic table is known as the alkali metals group. It includes elements such as lithium, sodium, potassium, rubidium, cesium, and francium. These elements are highly reactive and typically form +1 cations.
The element with the longest covalent radius among Li, B, N, and F is Li. This is because as you move down a group in the periodic table, the atomic radius increases due to the addition of new electron shells. The covalent radius generally follows this trend.
