In the early 1900s, Ernest was like the Gordon Ramsay of atomic science, using his trusty alpha particles (the bad boy particles) to bombard gold atoms.
Imagine this: he fired these alpha particles, like tiny bullets, at gold atoms, and they bounced back like crazy. It was like watching a game of atomic pinball! But here’s the twist, some of those particles didn’t bounce back. It was as if they had disappeared into thin air.
Rutherford realized that these missing particles must have crashed into something really dense in the atom, which he called the nucleus. And that’s how he stumbled upon the idea that most of the atom’s mass was concentrated in its tiny core, which contained protons (the positive guys) and neutrons (the neutral buds).
But wait, there’s more! Rutherford also figured out that the electrons (the negative Nancy’s) didn’t reside in the nucleus. They had to be somewhere else, dancing around the nucleus like little bees buzzing around a honeycomb. And that’s how the concept of valence electrons was born.
So, thanks to Ernest Rutherford, we now know that valence electrons are the ones that hang out on the outskirts of an atom, determining its chemical behavior and making the world a better (and more colorful) place.
