This Russian professor created the Periodic Table of the Elements by organizing elements by atomic mass.
Who was Mendeleev?
100
When two atoms share or exchange electrons in a way that links themselves together.
What is a chemical bond?
100
When two or more substances combine without changing the nature of the component substances.
What is a mixture?
100
Solid solutions made of two or more metals.
What is an alloy?
200
Tiny particles too small to be seen with the unaided eye that make up all matter in the universe.
What are atoms?
200
The capital letter or combination of a capital letter and lower case letter that name the element.
What is the chemical symbol?
200
This forms when two or more atoms of the same kind join together chemically.
What is a molecule?
200
The substance that a solute is dissolved into.
What is a solvent?
200
A molecule that contains at least 2 different elements.
What is a compound?
300
These are the three parts of an atom.
What are Proton, electron, and neutron?
300
Three reasons why the noble gases different from most other elements.
What is they are colorless, odorless, and have all the electrons they need?
300
When two atoms share electrons to form a chemical bond.
What is covalent bond?
300
This makes metals stronger by adding metals or non-metals together.
What is the benefit of an alloy?
300
These electrons repel other electrons and are attracted to the protons forming bonds between atoms and making them stick together.
What are valence electrons?
400
The simplest form of matter that cannot be broken down without losing their chemical properties.
What is an element?
400
The large group of elements that have the properties of conducting heat and electricity and being able to be bent or stretched.
What are transition metals?
400
The elements in column 1 of the Periodic Table react easily with other elements compared to the elements in column 18 because of this.
What is they have an odd number of electrons?
400
The ability of one substance to dissolve into a solvent.
What is solubility?
400
How Mendeleev and other chemists were able to use the Periodic Table to organize elements.
What is arranging them by atomic mass?
500
This is found at the center of all atoms.
What is a nucleus?
500
The method Mendeleev used to organize the periodic table.
What is ordering by atomic mass?
500
An atom becomes an ion when this happens.
What is an atom that gains or loses an electron?
500
This forms when liquid mixtures contain small particles that do not separate out.
What is a colloid?
