The three main subatomic particles that make up atoms.
What are protons, neutrons, and electrons?
Subatomic particle that varies to make ions.
What are electrons?
Anions
What are negative ions?
Subatomic particle that varies to form isotopes.
What are neutrons?
Rows on the periodic table.
What are periods?
Protons plus neutrons
What is atomic mass?
"Magic" number of valence electrons.
What is 8?
Definition of malleable
What is can be bent into different shapes?
Atomic value that is different between isotopes of the same element.
What is atomic mass?
Group 17
What are the halogens?
The mass of an electron.
Number of valence electrons for group 2 atoms.
What is 2?
11
Phosphorus is number 15 on the periodic table and has a mass of 30.97. Most isotopes of phosphorus will have this number of neutrons.
What is 16?
Have luster, and are ductile and malleable.
What are transition metals.
This is why atoms are neutral.
What is they have the same number of protons and electrons?
Type of ion most commonly formed by group 16 elements.
What is -2?
Name of the last naturally occurring element on the periodic table.
What is uranium?
Neutrons have the same mass as this subatomic particle.
What is the proton?
Increases as you move down a group on the periodic table.
What is electrical conductivity, atomic radius, or number of energy levels?
Model representing atomic structure.
What is the Bohr Model?
Group of elements that typically form no ions.
What are the Noble Gases?
Characteristic of all elements in the actinide series.
What is radioactive?
On the periodic table, the mass of all the isotopes of an element.
What is average atomic mass?
Elements that are identified as metalloids, or semiconductors.
What are germanium, arsenic, tellurium, boron, silicon, antimony, polonium? (Name five)
