This page explores the trends in some atomic and physical properties of the Group 2 elements - beryllium, magnesium, calcium, strontium and barium. You will find separate sections below covering the trends in atomic radius, first ionisation energy, electronegativity and physical
The 4s electrons are also clearly the outermost electrons, and so will define the radius of the atom. The lower energy 3d orbitals are inside them, and will contribute to the screening. There is no longer any conflict between these properties and the order of orbital filling. The electronic structures of two more d-block elements.
Describes and explains how atomic radii vary around the Periodic Table. The type of atomic radius being measured here is called the metallic radius or the covalent radius depending on the bonding. If you don't know about hybridisation, just ignore this comment - you won't need it for UK A level purposes anyway.
Iron is fairly typical with a density of 7.89 g cm-3. There are two reasons for this: As you go across the period, the atoms get heavier. The relative atomic mass of calcium is 40, but the RAM of iron is 56, for example. Iron atoms are significantly smaller than calcium atoms. The radius of a calcium atom is 0.197 nm; the radius of
Magnesium atoms also have a slightly smaller radius than sodium atoms, and so the delocalised electrons are closer to the nuclei. Each magnesium atom also has twelve near neighbours rather than sodium's eight. Both of these factors increase the strength of the bond still further. Metallic bonding in transition elements.
The 3+ charge is no longer located entirely on the iron but spread out over the whole ion - much of it on the hydrogen atoms. . If it is true that the smaller the ionic radius, the stronger the acidity of the hexaaqua ion, you would expect some sort of regular increase in pKa (showing weaker acids) as ionic radius increases.
He wanted to know: "Zinc's atomic radius is 0.137nm while copper's is 0.128 nm (taken from my A level text). So why . . . is the ionization energy of zinc higher?" He also asked: "Like atomic radius and ionization energy, does ionic radius (for some particular charge, say 2+) follow the same pattern as atomic radius?".
