Can we have element with atomic number 1.5?

No, we can't. Atomic number of a neutral atom is the no. of protons in its nucleus. No. of protons is always a positive integer. Additionally, protons are made of quarks held by gluons. Having atomic number 1.5 will give 1.5 positive charge on nucleus. So, any possible combination of quarks won't give that charge. read more
