Show me the element
An alkali metal, found in bananas.
Potassium.
Element with different amount of neutrons
Isotope
The only metalloid that is a halogen
Astatine
Composed of inert gases
Noble gases
Smaller atomic radius calcium or strontium.
Calcium
Why did Antoine lavosier disagree with greeks?
The only noble gas with 2 valence electrons.
Helium
The amount of protons in an atom
Atomic number
This element was names after the man who's experiment discovered the nucleus.
Rutherfordium
A gas that is in a group with very reactive metals
Hydrogen
Both the smallest element and the inert.
Helium.
Came up with octaves.
John Newlands
Element with best level of ductility, we use it on our wires.
Copper
Amount of protons and neutrons
Atomic mass
Group 15, series 2
Nitrogen
Considered semiconductors
Metalloids
Subatomic particles that add bulkiness to atoms, making them have a larger radius.
Electrons
Symbols and compounds were named because of this man.
Jacob Berzelius
Has the highest electrongetaivity.
Flourine.
Element W
Tungsten
The only element that is a liquid when found in room temperature. Also found thermometers
Mercury
Groups has a charge of +1
Alkali metals
Has a greater electrongetivity, sodium or magnesium.
Magnesium
Dimitri Mendeleev's ideas.
left spaces for future elements
This element was named after the furthest planet from the sun...or is it still a planet...
Plutonium
Shares the amount of valence electrons.
Family
Group 2, series 5
Strontium
This group has 1 to 2 valence electrons
Transition metals
The ability of the atom to attract and hold other atoms.
Electronegativity.
What did Johann Dobbereiner do? it may be a little musical...
triad idea of periodicity.
This element is found in our red blood cells.
Iron
Increases as you move down in the periodic table
Energy levels
This element was given its name after the greek titan that gave fire to humans
Promethium
Group with a +2 charge.
Type of relationship that occurs when one factor increases, the other decreases. Atomic radius and electronegativity has this.
Inverse relationship.
Assembles the periodic table by atomic number.
Henry Moseley
