It's Element-ary
The number of protons in an atom is also called this.
What are atoms?
An object's density is equal to it's mass divided by this.
What is it's volume?
Sweetened tea would be an example of this special kind of mixture.
What is a solution?
The tiny central part of the atom containing protons and neutrons.
What is the nucleus?
The simplest form of matter that cannot be broken down into other substances by chemical means.
What is an element?
The atoms of hydrogen and oxygen combine to form this.
What is a molecule?
A solid object will do this if its density is less than the liquid it is placed in.
What is float?
A pure substance made of two or more elements chemically combined.
What is a compound?
The sum of protons and neutrons in the nucleus.
What is the mass number?
An atom of the same element that has a different number of neutrons is called this.
What is an isotope?
The size of a salt crystal would be this kind of property.
That is physical?
An object with a mass of 25 g and a volume of 5 mL has this density.
What is 5g/mL?
A property of matter that can be observed without changing the substance’s identity.
What is a physical property?
What is neutral?
All atoms of oxygen have 8 protons, but oxygen-18 has this many neutrons.
What is 10?
Form of matter containing only one type of atom.
What is an element?
The method of finding the volume of an irregular object by placing it in water and measuring the change.
What is displacement?
These determine how an element will change when it reacts with another element.
What are chemical properties?
This negatively charged particle orbits the nucleus.
Chlorine has 17 protons. A chlorine-37 isotope has this many electrons?
What is 17?
A combination of two or more substances that are physically blended but not chemically bonded.
What is a mixture?
Comparing the density of one substance to another is called this.
What is relative density?
Very low temperature is required to make materials into these.
What are superconductors?
An atom that has lost or gained electrons, giving it a charge, is called this.
What is an ion?
