Sb (antimony)
Arsenic has 5 [valence electrons] in them.
As: Arsenic 33
In arsenic triiodide (AsI3), arsenic (As) typically has five valence electrons, while each iodine (I) atom has seven valence electrons. In the molecule, arsenic forms three covalent bonds with three iodine atoms, using three of its valence electrons. This leaves arsenic with two unshared electrons, which can be considered as one lone pair. Therefore, there is one ion pair of electrons associated with the arsenic in AsI3.
Arsenic (As) has five valence electrons, which places it in Group 15 of the periodic table. Elements that share the same number of valence electrons include phosphorus (P), antimony (Sb), and bismuth (Bi), as they are also in Group 15. Additionally, these elements exhibit similar chemical properties due to having the same valence electron configuration.
Sb (antimony)
Sb (antimony)
The chemical element arsenic, or As, is in group 15, period 4. Thus its electron configuration is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p3. Since its outermost shell is 4, arsenic has 5 valence electrons.
a lot
Antimony (Sb, # 51) has 5 valence electrons (and so do all the other elements in that group.)
six valence electrons
Arsenic has 5 valence electrons.
Arsenic has 5 [valence electrons] in them.
As: Arsenic 33
Arsenic has a mass number of 33 with an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3. This means that there are 3 valence electrons.
