- 1Module 6.1: ElementsBy: Sabaa Khan 8B
- 2Define atoms and what type of microscope it can be seen with.Atoms: Building blocks of every substance on the universe
Can only be seen with a scanning tunnelling microscope (STM)
- 3What is an element?A substance that is just made up of one type of atom.
- 4What are properties?A unique set of characteristics that scientists refer to while talking to substances.
- 5List the properties of metallic elements:1) Lustrous
2) Solid at room temperature
3) Good conductors
4) Malleable
5) Ductile
- 6Give 3 examples of basic metallic elements:1) Iron
2) Gold
3) Mercury
- 7What are the basic properties of non-metallic elements?1) Dull
2) Insulator
3) Brittle - 8Give 3 examples of non-metallic elements:1) Iodine
2) Sulfur
3) Neon
(Krypton as well for Mariam)
- 9How many elements are there and how many are natural?118, 98 are natural and 20 are artificial.
- 10Where are the elements shown and how are they are organised?The periodic table and they are organised according to weight, from lightest to heaviest.
- 11What is a chemical symbol? Give an example:Either a shorter version for the element straight from the element or from their Latin name.
Eg. Magnesium = Mg
Tungsten = Wolfram = W - 12What are three ways atoms can exist?1) Single atoms
2) A cluster of atoms also known a molecules
3) Large grid-like structures called crystal lattices - 13Define monatomic:An element made up of many individual atoms known as monatomic
- 14Give examples of monatomic elements:Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xexon (Xe), Radon (Rn)
- 15What are molecular elements?Clusters of two or more atoms bonded together. For example N2
- 16What is a crystal lattice?A large grid-like structure that repeats the same arrangement of atoms over and over.
- 17Metallic Lattices: What are they?The atoms in metals form lattice. Its structure makes them dense, solid and strong and can be hammered because it is weakly bonded.
- 18What are non-metallic lattices?Only a few non-metallic forms lattices such as silicon
- 19Yes, I used the same picture because my media is full and i wasted 1 hour trying to solve it and disclaimer it didn't work...
