Question

what is this 8 like symbol in chemistry (polar covalent bond)​

Answer 1

${\boxed{\underline{\tt{ \orange{Required \: \: Answer:-}}}}}$

Delta

(uppercase Δ, lowercase δ )

In the system of Greek numerals it has a value of 4. It was derived from the Phoenician letter dalet , Letters that come from delta include Latin D and Cyrillic Д.

A symbol which indicates that an atom or region with a deficiency of

• electron density,

• often because of resonance delocalization,

• electronegativity differences,

• or inductive effects.

EXAMPLE:-

EN C (2.5) < EN Cl (3.0) ΔEN = 3.0 - 2.5 = 0.5.

Therefore the carbon-chlorine bond of chloromethane is a polar covalent bond.
