Elena-2011 [213]

Ti is a transition metal.

<h3>Further explanation</h3>

Chemical symbol represent element or compound

The elements are arranged in the periodic system

  • 1. 22

This is the atomic number of Titanium

The Atomic Number (Z) indicates the number of protons of an element

  • 2. Ti

This is the symbol (chemical formula) of titanium

  • 3. 47.90

This is the mass number of Titanium

Mass Number (A) = Number of protons + Number of Neutrons

Atomic Number (Z) = Mass Number (A) - Number of Neutrons

  • 4. Titanium

This is the name of the element

To determine which group, alkaline, alkaline earth or transition it can be seen from the electron configuration

alkali and alkali earth : configuration from orbital 1s-7s

transition : configuration from orbital 3d-6d (Block d)

Electron configuration from Ti : [Ar] 3d²4s²

if we look at the configuration, then Ti is in the d block which is included in the transition metal
