Atomic Theory
These subatomic particles are found in the nucleus of an atom
What are protons and neutrons?
This is how Mendeleev originally organized the periodic table.
What is increasing atomic mass?
This is the atomic number of Calcium
What is 20?
This is the name for the electrons on the outer most shell.
What are valence electrons?
This is the type of bond that forms between nonmetal atoms.
What are covalent bonds?
The atomic number is equal to this number of subatomic particles.
What are protons?
This is how the periodic table is currently arranged.
What is increasing atomic number?
If an element has an atomic mass of 25 and an atomic number of 12, this is the number of neutrons.
What is 13?
This is the number of valence electrons for elements in group 14.
What is 4?
This is the bond that forms between metals and nonmetals
What are ionic bonds?
Atomic mass is equal to the addition of these two values.
What is protons plus neutrons?
This is the most reactive group of metals
What are alkali metals?
This is what is means to be periodic.
What is having a repeating pattern?
This diagram shows only the valence electrons for an element.
What is an electron dot diagram?
this is a type of covalent bond that has unequal sharing of electrons.
What is a polar bond?
This subatomic particle has basically no mass compared to the other two.
What are electrons?
This is the group of elements that never reacts.
What are the noble gases?
This group of elements are all known for forming salts
What are halogens?
These are three properties of metals.
What are reactive, malleable, ductile, luster, conductivity?
These are three properties of ionic compounds.
What are crystals, high melting point, and electrical conductivity?
This idea of Dalton's was proved wrong with isotopes.
What is all atoms of the same element are exactly alike?
We can predict element properties based off this.
What is group number?
These are the four items found in the cells in the periodic table
What are element symbol, atomic number, atomic mass, and element name?
These are three properties of nonmetals.
What are poor conductors, dull, brittle
These are two properties of covalent compounds.
What are low melting points and di not conduct heat or electricity?
