100
Smallest particle of an element. Basic unit of matter.
What is an atom?
100
Atoms of the same element that have different numbers of neutrons
What is an isotope?
100
A table that shows the elements, their atomic number, symbol, and average atomic mass; elements with similar chemical properties are grouped together.
What is the periodic table?
100
Elements that are good conductors of heat and electric current.
What is a metal?
100
Elements that are poor conductors of heat and electric current. Most are gases, dull & brittle
What is a non-metal?
200
Proton Neutron Electron
What are the parts of the atom?
200
By its mass number
How can you identify an isotope.
200
The property of a material that can be drawn into long wires.
What is ductility?
200
Alkali, and Alkali Earth metals.
What kind of metals are there?
200
Brittle and dull
What is a property of non-metals?
300
The number of protons in the nucleus of an atom
What is an atomic number?
300
A carbon-12
What is the most common isotope of carbon?
300
1. Alkali metals, 2. Alkali Earth metals, 3. Transition metals, 4. Other metals, 5. Semimetals, 6. Nonmetals, 7. Halogens, 8. Inert or noble gases.
What is the order of the periodic table groups from left to right.
300
The ease and speed which a substance reacts with another substance.
What is reactivity of a metal?
300
Halogens
What is a type of non-metals?
400
37
What is the atomic number in Rubidium?
400
3 isotopes
How many isotopes does hydrogen have?
400
Atomic number, Chemical symbol, element name, atomic mass.
What information is in an element square?
400
They move atomic nuclei faster and faster until they have reached really high speeds
What do particle accelerators do?
400
It's a big part of chemistry of life. Living things contain molecules with long chains of carbon.
What is special about carbon?
500
There is a cloud of electrons around the nucleus of protons and neutrons.
What does the modern atomic model look like?
500
The sum of protons and neutrons
What is an isotopes mass number.
500
Average mass of all isotopes of the element.
How do you find the average atomic mass?
500
Curium
What was the first synthetic element?
500
The liquid it reacts in.
How is reactivity measured?
