THE ATOM
Paper, plastic, wood, glass, skin - everything!
How many atoms make up the Periodic Table?
118
True or False, atoms are electrically neutral?
True.
What is created when protons and neutrons move around in the nucleus?
Electromagnetic radiation or gamma rays.
They surround the nucleus like the layers of an onion.
Name the differences between molecules, lattices and element.
Molecules have the same arrangements of atoms, lattices form grid like structures and vary in size and element are made up of the same atoms.
How is the Periodic Table ordered?
From smallest to largest.
If an electron is removed or added, what is the atom now called?
An ion.
What is transmutation?
What atom found on the periodic table has the highest amount of electrons and electron shells?
Ununoctium, 118 electrons across 6 shells.
Name the subatomic particles found inside an atom.
Name 5 atoms found on the Periodic Table (without looking at the Periodic Table) and list their atomic number.
Mrs. Jenkin to decide if the group is correct.
What is the difference between a Cation and an Anion?
A positively charged ion is called a Cation, and a negatively charged ion is called an Anion.
What is a stable nuclei?
The nuclei will never undergo nuclear decay.
How many electrons can the first electron shell hold?
2.
What does the atomic number represent?
The number of protons and electrons found in the atom. For example: Hydrogen has the number 1, therefore it has 1 proton in the Nucleus and 1 Electron found on the first shell.
What 3 pieces of information are found in one square on the Periodic Table?
The atomic number, symbol and the atoms name.
If an ion becomes positively charged, does it gain or loose an electron?
Looses an electron.
Name the three types of nuclear decay.
Alpha decay, Beta decay and Gamma decay.
How many electrons can the second electron shell hold?
8.
What is an Isotope?
These are atoms that have the same number of protons but different number of neutrons.
Are Hydrogen, Helium and Neon a non metal, metal or metalloids.
Non metals.
What is a ionic compound?
Its a structure that is formed when anions and cations come together to form large crystal lattices.
Explain the Half Life phenomenon.
Half Life is the time it takes for half the nuclei to decay.
What is electron configuration?
The number of electrons in each shell of an atom. For example, carbon has 6 protons and 6 electrons. The first 2 electrons fill the 1st electron shell, and the remaining 4 electrons on into the 2nd electron shell.
