Number of neutrons in lawrencium
WebAnswer (1 of 3): Lawrencium has a half-life if a bit over two and a half minutes. Ten minutes after you make your bomb, there wouldn’t be enough lawrencium left to make it go boom. You’d never have time to finish putting it together, much less loading it into a plane or bolting it to a missile. ... WebNeutron = 40 – 18 = 22. Therefore, an argon atom has twenty-two neutrons.
