Trend down a group

Definition of ionisation energy and the general trend down a group, using group 2 as an example. Progressing down group 1, the atomic radius increases due to the extra shell of electrons for each element. Going down the group, the first ionisation energy decreases. There is more shielding between the nucleus and the outer electrons and the distance between the nucleus and the outer electron increases and therefore the force

As with ionization energy, there are two rules that govern the periodic trends of electron affinities: Electron affinity becomes less negative down a group.

Definition of ionisation energy and the general trend down a group, using group 2 as an example. Progressing down group 1, the atomic radius increases due to the extra shell of electrons for each element. Going down the group, the first ionisation energy decreases. There is more shielding between the nucleus and the outer electrons and the distance between the nucleus and the outer electron increases and therefore the force Trend in the melting point down the group. We know that the atomic radii increases down the group. So, less energy is required to pull out the outermost electron as we go down the group, hence, gradually melting point decreases down the group. Progressing down group 2, the atomic radius increases due to the extra shell of electrons for each element. Going down the group, the first ionisation energy decreases. There is more shielding between the nucleus and the outer electrons and the distance between the nucleus and the outer electron increases and therefore the force of attraction between the nucleus and outer most electrons is reduced. The covalent radius (a measure of how large individual atoms are) shows different trends if you are moving across a period or down a group. A comparison of the relative covalent radii of atoms is

From top to bottom down a group, electronegativity decreases. This is because atomic number increases down a group, and thus there is an increased distance between the valence electrons and nucleus, or a greater atomic radius. Important exceptions of the above rules include the noble gases, lanthanides, and actinides.

WHY? - The number of energy levels increases as you move down a group as the number of electrons  A discussion of group trends in terms of ionisation energies, melting points, boiling points, atomic radii, ionic radii, metallic/non-metallic character of the element,  As we go down a group, the outermost electron of an atom is placed in a shell that is further from the nucleus.

- The number of energy levels increases as you move down a group as the number of electrons increases. Each subsequent energy level is further from the nucleus than the last. Therefore, the atomic radius increases as the group and energy levels increase.

Down a group of the periodic table, the atomic radius increases. As we go down a group, the outermost electron of an atom is placed in a shell that is further from the nucleus. This means it experiences the electrostatic attraction of the positive nucleus less. In general, what is the trend in I.E. as you go down a group? Explain why. The I.E. decreases as you go down a group because the bigger the atom is the farther the electrons are from the pull of the nucleus so the easier they are to remove There is no change going down a group. However, this periodic trend is sparsely followed for heavier elements (elements with atomic number greater than 20), especially for lanthanide and actinide series. The greater the number of core electrons, the greater the shielding of electrons from the core charge of the nucleus. As you go down group 1 from top to bottom, the mass of a cubic centimetre of element has a tendency to increase. That is, the density of group 1 elements shows a "general trend" of increasing as you go down the group from top to bottom. As you go down group 1 from top to bottom, the mass of the element present per unit volume, in general
