What is the structure of yttrium?
What is the structure of yttrium?
Yttrium exists in two allotropic (structural) forms. The α-phase is close-packed hexagonal with a = 3.6482 Å and c = 5.7318 Å at room temperature. The β-phase is body-centred cubic with a = 4.10 Å at 1,478 °C (2,692 °F). Yttrium and its compounds have numerous uses.
What is yttrium valence electrons?
Yttrium commonly has an oxidation state of +3 since it gives three valence electrons.
What is the electrons for yttrium?
2,8,18,9,2Yttrium / Electrons per shell
What is electron diagram?
An electron configuration diagram is a model that depicts the position of electrons as they orbit the nucleus of an atom. Electrons are represented by dots or crosses and are positioned in energy levels, or ‘shells’, around the central nucleus. This is sometimes called the Bohr, or the ‘solar system’, model.
What’s the definition of yttrium?
Definition of yttrium : a metallic element with atomic number 39 usually included in the rare-earth group that occurs usually with other rare earth elements in minerals and is used especially in phosphors, YAG lasers, alloys, and treatments for certain cancers — see Chemical Elements Table.
How many electrons does ytterbium have?

How many neutrons and electrons are in yttrium?
The nucleus consists of 39 protons (red) and 50 neutrons (blue). 39 electrons (green) bind to the nucleus, successively occupying available electron shells (rings).
Why does yttrium have 3 valence electrons?
The number of unpaired electrons in the last orbit of an element is the valency of that element. During compound formation, the yttrium atom donates three electrons to another atom and the oxidation state of yttrium is +3. Therefore, the valency of the yttrium element is 3.
