Atoms are the basic building blocks of all
matter
they’re extremely small, make up everything
in our universe
stars, these bananas, and our entire body
all made of tiny atoms fit together differently
atoms are made up of three particles called
electrons, protons, and neutrons
electrons are the smallest, their charge is
negative
spinning really fast all around the nucleus
the proton’s positive and located in the center
forming the nucleus with neutrons, that have no charge at all
when particles amounts different
makes various elements
one proton, one electron, the simplest atom
is hydrogen
every element has its own atomic number
tells us how many protons located in its center
less protons means less mass
like hydrogen that’s a gas
it is less dense than the air, one proton
in the nucleus
because protons have a strong positive charge
push each other away, but pulled back with a strong nuclear force
balance makes atoms possible
everything in the universe
different atoms clumped together are known as molecules
