(= number &rest more-numbers)
Function: Return T if all of its arguments are numerically equal, NIL otherwise.
Example:
(defun atomic-number-element (atomic-number)
  "Get an element from its atomic number"
  (find-element-if
   (lambda (element)
     (= (element-atomic-number element)
        atomic-number))))
