It says that all metals form positive ions in a reaction but it doesn’t make sense for me considering there are metals in group 5 and 6 which means they would have to gain electrons making the ion negatively charged. Then how come all metals are form positive ions… Someone please explain..

Groups 5 and 6 are not Metals, they’re Transition Metals. That’s a pedantic distinction, as they both share very similar properties, but the transition metals act slightly differently because of which type of electron shell the valence shell is. Metals do give up an electron due to the outer most electron shell (s-shell) being incomplete and the electrons in that shell are weakly held. The transition metals vary in how strongly they hold on to their valence electrons (d-shell), meaning they can be negatively and positively ionized depending on which element it is.
