There are 7 elements that are classified as “other metals”. These elements are located in groups 13, 14, and 15.
Such elements are ductile and malleable, although they are not the same as the transition elements. These elements do not exhibit variable oxidation states. Also their valence electrons are only in their outer shell.
The following elements below are solid, opaque and have a relatively high density. They have oxidation numbers of +3, ±4, and -3.
| Name | Symbol | Atomic Number | Atomic Weight |
|---|---|---|---|
| Aluminum | Al | 13 | 26.981539 |
| Gallium | Ga | 31 | 69.723 |
| Indium | In | 49 | 114.818 |
| Tin | Sn | 50 | 118.71 |
| Thallium | Tl | 81 | 204.3833 |
| Lead | Pb | 82 | 207.2 |
| Bismuth | Bi | 83 | 208.98037 |
Aluminium is a chemical element with the atomic number 13 in the periodic table of elements. It’s the most plentiful metal found in the Earth’s crust. Being a member of the boron family of periodic table elements, this strong and light-weight metal has three valence electrons that help aluminium make numerous compounds with the other … Read more
