  2. Antimony - Wikipedia

    en.wikipedia.org/wiki/Antimony

    Electron configuration 4d 10 5s 2 5p 3: Electrons per shell: 2, 8, 18, 18, 5: ... Antimony is a chemical element; it has symbol Sb (from Latin stibium) and atomic ...

  3. Electron configurations of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Electron_configurations_of...

    This page shows the electron configurations of the neutral gaseous atoms in their ground states. For each atom the subshells are given first in concise form, then with all subshells written out, followed by the number of electrons per shell. For phosphorus (element 15) as an example, the concise form is [Ne] 3s 2 3p 3.

  4. Pnictogen - Wikipedia

    en.wikipedia.org/wiki/Pnictogen

    Pnictogen. The pnictogens[1] (/ ˈpnɪktədʒən / or / ˈnɪktədʒən /; from Ancient Greek: πνῑ́γω "to choke" and -gen, "generator") are the chemical elements in group 15 of the periodic table. This group is also known as the nitrogen group or nitrogen family. Group 15 consists of the elements nitrogen (N), phosphorus (P), arsenic (As ...

  5. Post-transition metal - Wikipedia

    en.wikipedia.org/wiki/Post-transition_metal

    Aluminium is an undisputed p-block element by group membership and its [Ne] 3s 2 3p 1 electron configuration, but aluminium does not literally come after transition metals unlike p-block metals from period 4 and on. The epithet "post-transition" in reference to aluminium is a misnomer, and aluminium normally has no d electrons unlike all other ...

  6. Metalloid - Wikipedia

    en.wikipedia.org/wiki/Metalloid

    It melts at 631 °C. Antimony is a semimetal with an electrical conductivity of around 3.1 × 10 4 S•cm −1 [363] and a band overlap of 0.16 eV. [337] [n 39] Liquid antimony is a metallic conductor with an electrical conductivity of around 5.3 × 10 4 S•cm −1. [365] Most of the chemistry of antimony is characteristic of a nonmetal. [366]

  7. Electron configuration - Wikipedia

    en.wikipedia.org/wiki/Electron_configuration

    Electron configuration. In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. [1] For example, the electron configuration of the neon atom is 1s2 2s2 2p6, meaning that the 1s, 2s, and 2p subshells are occupied by ...

  8. Properties of nonmetals (and metalloids) by group - Wikipedia

    en.wikipedia.org/wiki/Properties_of_nonmetals...

    Antimony melts at 630.63 °C and boils at 1635 °C. It is a semimetal, with an electrical conductivity of around 3.1 × 10 4 S•cm −1 and a band overlap of 0.16 eV. Antimony has a moderate ionisation energy (834 kJ/mol), moderate electron affinity (101 kJ/mol), and moderate electronegativity (2.05).

  9. Group 3 element - Wikipedia

    en.wikipedia.org/wiki/Group_3_element

    Group 3 element. Group 3 is the first group of transition metals in the periodic table. This group is closely related to the rare-earth elements. It contains the four elements scandium (Sc), yttrium (Y), lutetium (Lu), and lawrencium (Lr). The group is also called the scandium group or scandium family after its lightest member.
