What is a complex/coordination compound?
Correct answer: A. A compound in which a metal atom or ion is covalently bonded with a group of neutral molecules or anions.
- A. A compound in which a metal atom or ion is covalently bonded with a group of neutral molecules or anions.
- B. A compound that contains 2 or more than 2 different elements
- C. A compound which has complex molecular geometry
- D. A compound that contains a complex ion and can exist independently
Explanation
A coordination complex is the product of a Lewis acid-base reaction in which neutral molecules or anions (called ligands) bond to a central metal atom (or ion) by coordinate covalent bonds.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
