ATOMS Flashcards
ALL SUBASTANCES ARE MADE UP OF (…)
ATOMS
ATOMS ARE REALLY (…)
TINY, TO SMALL TO SEE WITH A MICROSCOP
ATOMS CONTAIN…
PRONTONS, NEUTRONS AND ELECTRONS
WHAT ARE PROTONS, NEUTRONS AND ELECTRONS
SUBATOMIC PARTICLES
WHAT ARE PROTONS
THEY ARE HEAVY AND POSITIVELY CHARGED
WHAT ARE NEUTRONS
THEY ARE HEAVY AND NEUTRAL
WHAT ARE ELECTRONS
THEY HAVE HARDLY ANY MASS, THEY ARE NEGATIVELY CHARGED
WHAT ARE THE CHARACTERISTICS OF A NUCLEUS
1) ITS IN THE MIDDLE OF AN ATOM
2) IT CONTAINS PROTONS AND ELECTRONS
3) IT HAS POSITIVE CHARGE BECAUSE OF PROTONS
4) ALMOST THE WHOLE MASS OF THE ATOM IS CONCENTRATED IN THE NUCLEUS
5) COMPARED TO THE ATOM THE NUCLEUS IS TINY
CHARACTERISTICS OF ELECTRONS
1) THEY MOVE AROUND THE NUCLEUS IN ENERGY LEVELS CALLED SHELLS
2) THEY ARE NEGATIVELY CHARGED
3) THEY ARE TINY BUT THEIR ORBITALS COVER A LOT OF SPACE
NEUTRAL ATOMS HAVE (…)
NO CHARGE OVERALL
THE CHARGE ON THE ELECTRONS IS THE SAME SIZE AS THE CHARGE ON THE PROTONS BUT (…)
OPPOSITE
THE NUMBER OF (…) ALWAYS EQUAL THE NUMBER OF (…) IN A NEUTRAL ATOM
ELECTRONS/ATOMS
IF SOME ELECTRONS ARE (…) THE ATOM BECOMES CHARGED AND BECOMES AN (…)
ADDED OR REMOVED/ ION
WHAT IS THE ATOMIC NUMBER
TELLS YOU HOW MANY PROTONS THEY ARE
ATOMS OF THE (…) ALL HAVE THE SAME NUMBER OF PROTONS
SAME ELEMENT
