Electron configurations are a shorthand form of an orbital diagram, describing which orbitals are occupied for a given element. for example, 1s22s22p1 is the electron configuration of boron. use this tool to generate the electron configuration of arsenic (as).

[Ar] 4s² 3d¹⁰ 4p³

Explanation:

Arsenic has an atomic number of 33, thus 33 protons and 33 electrons. The electron configuration is:

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p³

The shorthand notation includes the previous noble gas to represent the inner electrons. The gas previous to arsenic is argon, with 18 electrons. The shorthand notation for arsenic is:

[Ar] 4s² 3d¹⁰ 4p³

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

answer: they produce more slow than unicellular organisms.
