Scandium, I believe it has something to do with that fact that it has the ability to have a double bond in ionic bonds.
These diamagnetic metals between transition metals from the period 4 are copper and zinc.
The third period element that forms a 3- ion is sulfur.
Iron oxide (Fe2O3), also known as rust, is an example of an oxide of a transition element. It is a common compound that forms when iron reacts with oxygen in the presence of water or air.
The cation is the metal "Cu", otherwise known as the element Copper.
When an element is completely burned in oxygen, it forms an oxide. The specific oxide produced depends on the element. For example, carbon burned in oxygen forms carbon dioxide, sulfur forms sulfur dioxide, and iron forms iron(III) oxide.
Lithium is a main element in the period tabel taht forms a strong base when mixed with water. The reaction results in LiOH.
Chromium (Cr) is a period 4 transition element that can form a 2+ ion with a half-filled d sublevel. In its 2+ ion state, chromium has a d5 configuration, with the 3d orbital half-filled.
Silver
The third period element that forms a 3- ion is sulfur.
Iron oxide (Fe2O3), also known as rust, is an example of an oxide of a transition element. It is a common compound that forms when iron reacts with oxygen in the presence of water or air.
Aluminum
Aluminum (Al) always forms a 3+ cation in its 3rd period of the periodic table.
Selenium forms selnides which contain the ion Se2-.
The cation is the metal "Cu", otherwise known as the element Copper.
Scandium is the smallest d-block element which in the past also made it the smallest transition metal. However, using the accepted modern definition of a transition metal: 'a transition metal is one which forms one or more stable ions which have incompletely filled d orbitals' scandium would not count as a transition metal, as it always forms 3+ ions with no d-electrons. Using this definition, the smallest transition metal would therefore be titanium.
Gold is a transition metal on the periodic table.The processes under which gold forms and gets transported definitely falls within the confines of geology and the fact that gold is a mineral makes geology the primary field to study it.
I believe it is group 11 since it is a group in the transition metal class, and transition metals form ions with color.
The basic element is carbon.
