The bond between atoms of two elements having atomic numbers 37 and 53 is:
Correct answer: A. Electrovalent
- A. Electrovalent
- B. Hydrogen
- C. Co-ordinate
- D. Covalent
Explanation
Electronic configuration of atom with atomic no. 37 is:1s22s22p63s23p64s23d104p65s1or [Kr]5s1Electronic configuration of atom with atomic no. 53 is:1s22s22p63s23p64s23d104p65s24d105p5or [Kr] 5s24d105p5The atom with atomic no. 53 needs 1 electron to complete its shell while the one with atomic no. 37 has 1 electron in its outermost shell. The latter can lose this electron to form a cation. This electron will be gained by the former to form an anion. In this way, an ionic or electrovalent bond will be formed between the two atoms.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
