Elements
100
It makes up everything around us including living and non-living materials.
What are atoms?
100
There are two types of molecules known as
What are compound and elemental molecules?
100
It is how we can identify an element (hint: there are two)
What are physical and chemical properties?
100
It is the column (vertical) that places elements with similar characteristics together.
What are groups or families?
100
It is the a pure substance that cannot be broken down into other substances by chemical or physical means.
What are elements.
200
It is a subatomic particle that is found in the nucleus and is positively charged.
What is proton?
200
It is a type of molecule shown below
What is an elemental molecule?
200
It is a type of molecule that chemically bonds two or more of the SAME elements together.
What is an elemental molecule?
200
It is the horizontal rows that represent the number of electrons in the valence electron shell.
What are periods?
200
It is the section circled in the periodic table. Tell about its properties.
What are metalloids? They share properties of metals and non-metals. They can be shiny/dull, semi-conductors, and brittle.
300
It is the subatomic particles inside of an atom (name the charges as well)
a- electrons (negative)
b- neutrons (equal/zero/neutral)
c-protons (positive)
300
It is synonym for a molecule with two elements chemically bonded.
What is diatomic?
300
It is which type of property?
What is a physical property?
300
It is this element on the periodic table
What is calcium?
300
It is the group to the right of metalloids include their properties.
What are non-metals? They are not good conductors, low melting and boiling points, brittle
400
It is the function of each subatomic particle.
What is
nucleus- gives mass holds protons and neutrons
protons- positive energy level of element and attracted to electrons
electrons- orbit around nucleus determine energy level and attracted to protons
neutrons- stability and mass
400
Is the type of molecule H20, C02 and C6H1206
What is a compound molecule?
400
The are examples of chemical properties. Name at least four.
What are oxidation (rust), toxic, radioactivity, flammability, combustability
400
It is the patterns of which the periodic table is put together. Name at least four.
What are groups/families, periods, atomic number/protons/atomic mass, types of elements metals, metalloids and non-metals
400
It is the element found in group nine and period four.
What is Mt (element #109)
500
It is how atomic mass is found in a stable element.
What is the number of protons and neutrons added together.
500
It is the similarities shared between a compound and elemental molecules. Name at least 4
.What are both are made of atoms, types of molecules, subatomic particles, elements, chemically bonded
500
These are examples of physical properties. Name at least six examples
What are color, luster, density, volume, malleability, ductility, conductivity, magnetism?
500
It is the reason different periodic tables vary in the number of elements.
It is that new elements are being discovered.
500
It is the group and period number of Radium.
What is group 2 and period 7?
