What are Atoms
What exactly is an atom?
An atom is the smallest thing that still counts as an element. It’s like the basic unit for everything
Which part of the atom has a positive charge?
The proton—it’s positive, like a plus sign.
Where are the protons and neutrons found?
They’re both in the nucleus, which is the center of the atom.
What’s a molecule?
It’s when two or more atoms stick together to make something new, like water.
Why do atoms matter so much?
Atoms make up all matter, so without them, nothing—like, not even air or water—would exist.
Which part doesn’t have any charge at all?
The neutron. It’s neutral, so it’s not positive or negative.
Where do the electrons go?
They fly around the nucleus in what’s called the electron cloud.
How do atoms join together to make molecules?
They bond by sharing or exchanging electrons.
What are the main things atoms are made of?
They’re made of protons, neutrons, and electrons.
Which part is negative and moves around the outside?
The electron. It’s negative and goes around the nucleus.
What is the nucleus?
It’s the middle part of the atom that holds the protons and neutrons.
What’s the difference between an atom and a molecule?
An atom is just one, but a molecule is a bunch of atoms connected together.
What 3 main types of tiny particles that atoms are made up of?
Atoms are made of three main types of tiny particles are called :Protons,Neutrons ,and Electrons.
Which part hardly weighs anything?
The electron. Its mass is so tiny it’s like almost zero.
What does the number of protons tell you?
That’s the atomic number, which tells you what element it is. Like, oxygen always has 8 protons.
What atoms make up H₂O?
Two hydrogens and one oxygen.
