What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. It is a key factor in determining how atoms interact in chemical bonds.

What is a transition metal?

Back

Transition metals are elements found in the d-block of the periodic table, characterized by their ability to form variable oxidation states and colored compounds. Examples include iron (Fe), copper (Cu), and nickel (Ni).

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state. It is an important factor in determining an element's reactivity.
