What is atomic theory
Matter is anything that occupies space, as weight (mass), or requires energy to move. Matter consists of various sized particles, known as molecules.
What is a molecule
A molecule is the smallest particle that a compound to be broken down into and still retain the properties of that compound
What is a compound
A compound results from the combination of two or more different elements
What are molecules made up of
Elements
What are elements made up of
Atoms
What is an atom
The smallest particle of an element that retains the characteristics of that element
What does an atom consist of
Electrons, protons, neutrons.
What are electrons
They are negatively charged particles.
What are protons
They are positively charged particles.
What are neutrons
They are neutral particles
What are the two heaviest particles of an Atom
Protons and neutrons, this is why we are found in the center of an Atom
What our valence electrons
Electrons found in orbit on the outermost ring, this causes the electron to require less energy to be “knocked out of orbit”
What is a valence ring
The outermost ring of an Atom where electrons travel
The further away from the nucleus that an electron is…
The less energy is required to “knock that electron out of its orbit”.
