To calculate the bond length between two hydrogen atoms that are covalently bonded together, we need to first find the covalent radius of hydrogen. The covalent radius of hydrogen is approximately 31 pm picometers .Now, we can use the given formula to calculate the bond length : = 0.74 + Since both atoms are hydrogen, their covalent radii are the same: = 0.74 31 pm + 31 pm = 0.74 62 pm 45.88 pmSo, the bond length between two hydrogen atoms that are covalently bonded together is approximately 45.88 pm.
