Cards in this deck (17)
- 1WHAT ARE ATOMS?The fundamental building block of all materials; it consists of a cluster of protons and neutrons surrounded by a cloud of electrons.
- 2HOW CAN YOU SEE ATOMS?TO see atoms, scientists must use a special type of microscope.
- 3how many atoms are there in total?118
- 4HOW MANY ARE NATURAL AND HOW MANY ARE MAN-MADE?98 ARE NATURALLY FOUND
20 ARE MADE IN A LABORATORY
- 5WHAT ARE MOLECULES?A CLUSTER OF ATOMS THAT MAKES UP AN ELEMENT OR A COMPOUND
- 6WHAT ARE CRYSTAL LATTICES?A GRID-LIKE STRUCTURE OF ATOMS OR IONS IN WHICH EACH particle IS BONDED TO ALL OF ITS NEIGHBOURING ATOMS.
- 7WHAT IS AN ELEMENT?A SUBSTANCE MADE UP OF ONLY ONE TYPE OF ATOMS.
- 8WHAT IS THE ONLY NON METALLIC ELEMENT THAT CAN FORM CRYSTAL LATTICES?CARBON
- 9WHAT IS COMPOUND?A PURE SUBSTANCE THAT IS MADE UP OF TWO OR MORE DIFFERENT TYPES OF ATOMS.
- 10THE PARTS OF ATOMS?
- 11WHAT IS ATOMIC NUMBER?NUMBER OF PROTONS AND ELECTRONS.
- 12WHAT IS THE MASS NUMBER?A NUMBER OF PROTONS AND NEUTRONS.
- 13WHAT IS THE CATION?THE ION FORMED GIVES THE ATOM A POSITIVE CHARGE.
- 14HOW IS A CATION FORMED?IF AN ATOMS GAINS ELECTRONS THEN IT HAS MORE ELECTRONS THAN PROTONS
- 15WHAT ARE SUBATOMIC PARTICLES?THE PARTICLES THAT ATOMS ARE MADE OF PROTONS, NEUTRONS, AND ELECTRONS.
- 16WHAT ARE IONS?ATOMS CAN LOSE OR GAIN ELECTRONS TO BECOME ELECTRICALLY CHARGED PARTICLES.
- 17WHAT ARE ANION?AN ION THAT HAS MORE ELECTRONS THAN PROTONS AND IS NEGATIVELY CHANGED.
