Question | Answer |
What is an atom | The smallest part of matter |
What is the mass number | The amount of protons and neutrons |
What is the atomic number | Number of protons |
The number of electrons is the same as | The number of protons |
Shell one can have how many electrons | 2 |
Shell two can have how many electrons | 8 |
Shell three can have how many electrons | 18 |
What is the periodic table | An organised chart of all the known elements |
What are groups | The vertical columns on the periodic table |
What are periods | The horizontal rows on the periodic table |
Where are the transition metals found | In the middle of the periodic table |
Where are the halogens found | In group 17 |
What are the properties of halogens | brightly colored |
Why are the elements in Group 18 called noble gases | Because they have a full outer shell and don't react |
Where are the alkali metals found | Group one |
What are the characteristics of alkali metals | They react strongly to water and form basic solutions |
What are group two | the alkaline earth metals |
what is found on the left hand side of the table | the metals |
What are the 8 elements that are next to the zig zag line | They are metaloids |
What are some features of metals | They are solid at room temperature They are malleable. They can be made into a wire. They can be made shiny |
What are some feature of non-metals | They are usually dull or glassy Most are gases at room temperature They melt at low temperatures Most are poor conductors of heat and electricity They are brittle |
What features do metaloids have | They have features of both metals and non metals |
What is an atom made up of | A nucleus with protons and neutrons and several shells with electrons on the shells |
How many metaloids are there, name two | eight, boron and silicon |
What is electron configuration? | A list of the number of electrons in each shell. |
If the atomic number of Na is 11, what is the electron configuration | 2,8,1 |
What is an ion | A charges element or molecule |
What is a cation | A positive ion |
What is a anion | A negative ion |
What are ionic compounds made up of | A metal and a non metal |
What is matter made up of | atoms |
What are the 3 particles that atoms are made from and the charge they have | Protons: Positive Electrons: Negative Neutrons: Neutral |
What is in the periodic table | All of the known elements |
Where are the noble gases found on the periodic table? | Group 8 |
Why are the group 8 elements special | Because they have a full outer shell and don't react |
What are the group 8 elements called? | The noble gases |
What is a molecule | A group of atoms bounded together |
What is a compound | A mix of two different elements |
