Titanium
Element 22 of Periodic table is Titanium with atomic number 22, atomic weight 47.867. Titanium, symbol Ti, has a Simple Hexagonal structure and Silver color. Titanium is a Transition Metal element. It is part of group 4 (titanium family). Know everything about Titanium Facts, Physical Properties, Chemical Properties, Electronic configuration, Atomic and Crystal Structure.
History of Titanium
The element Titanium was discovered by W. Gregor in year 1791 in United Kingdom. Titanium was first isolated by J. Berzelius in 1825. Titanium derived its name from Titans, the sons of the Earth goddess of Greek mythology.
Gregor found an oxide of a new metal in ilmenite; Martin Heinrich Klaproth independently discovered the element inrutilein 1795 and named it. The pure metallic form was only obtained in 1910 byMatthew A. Hunter.
How to Locate Titanium on Periodic Table
Periodic table is arranged by atomic number, number of protons in the nucleus which is same as number of electrons. The atomic number increases from left to right. Periodic table starts at top left ( Atomic number 1) and ends at bottom right (atomic number 118). Therefore you can directly look for atomic number 22 to find Titanium on periodic table.
Another way to read periodic table and locate an element is by using group number (column) and period number (row). To locate Titanium on periodic table look for cross section of group 4 and period 4 in the modern periodic table.

Crystal Structure of Titanium
The solid state structure of Scandium is Simple Hexagonal.
The Crystal structure can be described in terms of its unit Cell. The unit Cells repeats itself in three dimensional space to form the structure.
The unit cell is represented in terms of its lattice parameters, which are the lengths of the cell edges Lattice Constants (a[295.08 pm], b[295.08 pm] and c[468.55 pm]) and the angles between them Lattice Angles (alpha, beta and gamma).
The positions of the atoms inside the unit cell are described by the set of atomic positions ( xi, yi, zi) measured from a reference lattice point.
The symmetry properties of the crystal are described by the concept of space groups. All possible symmetric arrangements of particles in three-dimensional space are described by the 230 space groups (219 distinct types, or 230 if chiral copies are considered distinct.

Ground State Electronic Configuration of Scandium- neutral Scandium atom
Abbreviated electronic configuration of Titanium
The ground state abbreviated electronic configuration of Neutral Titanium atom is [Ar] 3d2 4s2. The portion of Titanium configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [Ar]. For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used. This is important as it is the Valence electrons 3d2 4s2, electrons in the outermost shell that determine the chemical properties of the element.

Electrons are filled in atomic orbitals as per the order determined by the Aufbau principle, Pauli Exclusion Principle and Hund’s Rule.
- As per the Aufbau principle the electrons will occupy the orbitals having lower energies before occupying higher energy orbitals. According to this principle, electrons are filled in the following order: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p…
- The Pauli exclusion principle states that a maximum of two electrons, each having opposite spins, can fit in an orbital.
- Hund’s rule states that every orbital in a given subshell is singly occupied by electrons before a second electron is filled in an orbital.
