WebbThe radius for a cation is smaller than the parent atom (Al), due to the lost electrons; the radius for an anion is larger than the parent (S), due to the gained electrons. Cations with larger charges are smaller than cations with smaller charges (e.g., V 2+ has an ionic radius of 79 pm, while that of V 3+ is 64 pm). Webb6 dec. 2024 · Group 1 metals are less reactive than group 2 metals. Its valence shell contains 2 electrons. They have low electronegativity. Compounds of alkali metals are often insoluble in water. Alkaline metals are usually Shiny, silvery. They have ions with a +2 charge. They are solid. They are harder, denser, stronger.

Webb4 nov. 2024 · You may assume that the valences of the elements—the number of electrons with which an atom will bond or form—are those that can be derived by looking at the groups (columns) of the periodic table. While these are the most common valences, the real behavior of electrons is less simple. Here is a table of element valences. WebbAtomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period .
