Question

write the periodic trends in chemical properties ​

Answer 1

Answer:

Periodic trends are specific patterns in the properties of chemical elements that are revealed in the periodic table of elements. Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radii, ionic radius, metallic character, and chemical reactivity.

Answer 2

$\huge\bold\purple{Answer:-}$

Periodic trends in chemical properties:

The most fundamental chemical property of an element is its combining power. This property is numerically expressed in terms of valency or valence. Valency of an element indicates the number of chemical bonds that the atom can form giving a molecule. Another frequently used term related to valence is the oxidation state or oxidation number. Valence does not have any sign associated with it, but oxidation number does, and can be either + or — which is decided by electronegativities of atoms that are bonded
