Hey there!
Well, “Ca” is ‘Calcium’ the atomic number of calcium is 20 on the periodic table & “Ar” is ‘Argon’ and atomic number of argon is 18. But with Argon being a noble gas and it’s outer electron shell being already full of electrons with non to spare or receive, and Calcium only having 2 valence electrons.
The chemical bond would most likely be nothing even in a hypothetical situation
Good luck on your assignment & enjoy your day!
