Atom Knoladge Flashcards
Element
Pure substance made up of ONE type of atom
Compound
QIn compounds, the atom of one element is tightly bonded to the atom of another element or elements. Some compounds are made up of molecules instead of atoms e.g = common table salt.
Atom
All matter - everything - is made up of building blocks we call atoms.
The three particals that make up a atom is:
Protons - positive. Neutrons - neutral and electrons - negative
Protons are
Positive
Neautrons are
Neutral
Electrons are
Negative
In nature there are Naturally occurring elements
92
How natural atoms are there
92
How many shells can a middle shell holds
2 shells
The second shell can only hold
8 electrons
Electrons and protons are always
Equil
Protons have
Positive charge
Electrons have
Electric charge
What are the two particals that occurs in the center of an atom
Protons and neutrons
When protons and neutrons are put together you get
Nucleus
Can atoms be divided into smaller particles???
NO THEY CANT!!!
What does they period tell us
How many rings are around the atom like carbon has 2!!!! Because it’s on the 2nd period section.
All substances are made up of particals called …
Atoms
The atomic number tells us
Who many electrons AND protons there is / are
Electrons dont fly off their atoms because
Of the electric charge that keeps them spinning and spinning
What makes up an atom
EMPTY SPACE!!!
E- =
Inelectron shells
. =
Electron shell
What is a nucleus
It’s is the center of an atom
What is element in Greek
στοιχείο
What is atom in Greek
άτομο
How do you split water
water is split into hydrogen and oxygen via chemical reactions. The process will yield twice as much hydrogen as oxygen.
When atoms are joined in groups it is called
Molecules
What are molecules
Are what you get when you have a large group of atoms that are joined together.
What does atom mean in Greek
It comes from the two words a meaning not and Tomas meaning to cut. So our word atom some s form the word atoms meaning uncuttable.
