1.what is the coordinate?

2.what is the long-form electron configuration?

3.what is the short-hand electron configuration?

4.number of valence electrons?

Answer 1

Holmium's coordinate depends on the compound it forms, its long-form electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f11 5d1, its short-hand electron configuration is [Xe] 6s2 4f11 5d1, and it has 2 valence electrons.

Step-by-step explanation:

The element holmium (H.o) has the following characteristics:

1. Coordinate: In chemistry, the term 'coordinate' refers to the number of atoms, ions, or molecules that surround a central atom in a coordination complex. For holmium, the coordinate depends on the compound it forms. For example, in holmium chloride (HoCl3), the coordinate of holmium is 6 because 6 chloride ions surround it.
2. Long-form electron configuration: The electron configuration of holmium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f11 5d1. This shows the distribution of electrons in each energy level and orbital of the atom.
3. Short-hand electron configuration: The short-hand electron configuration of holmium is [Xe] 6s2 4f11 5d1, which represents the noble gas core (Xenon) followed by the valence electrons in the outermost energy level and the f and d orbitals.
4. Number of valence electrons: Valence electrons are the electrons in the outermost energy level of an atom. The outermost energy level for holmium is the 6s orbital, and the 4f and 5d orbitals are also considered valence orbitals. Therefore, holmium has 2 valence electrons.

Answer 2

1. The graph where x axis and y axis are present is called coordinate.
