Atoms
This is the positively charged particle found in the nucleus of an atom
What is proton
Horizontal rows in the periodic table are called
Periods
This is the ability to reflect light
shininess
This super machine is used to make synthetic elements
particle accelerators
Alkali metals can be found in this group of the periodic table
group 1
This is the particle found in the nucleus that does not have a charge
what is the neutron
vertical columns of the periodic table are called
Groups
This is the ability to conduct heat or electricity
conductivity
This is a gas-like state of matter consisting of high energy electrons that have been stripped away from the atom
plasma
Metals such as iron, copper and gold can be found in this group
transition metals
This is the number listed at the top of the period square which represents the number of protons in an element's nucleus
Atomic number
Dmitri Mendeleev found there was a pattern to the properties when elements were arranged in order of increasing this
atomic mass
This is the ability to be hammered, pressed, or rolled into thin sheets
malleability
These are elements that form molecules consisting of two atoms bonded together.
diatomic elements
Alkaline earth metals can be found in this group
group 2
When a scientist uses a diagram or an object to explain the structure of atoms, the scientist is using this
A model
This is the group of elements located along a zig zag line in the periodic table
Metalloids
Chemical property in which a metal undergo destruction in the presence of another substance.
Corrosion
This is the most abundant element on earth and is rarely found alone in nature, it is commonly found with oxygen in water.
Hydrogen
This group of non-metals are the most reactive
halogens
element that contain equal numbers of protons but different numbers of neutrons in their nuclei are this
isotopes
Elements located to the right of the "staircase" are these
nonmetals
Chemical property which measures how easily an element will combine with other elements to form compounds
reactivity
This process occurs when two or more atomic nuclei are combined to form one atomic nuclei
nuclear fusion
This group of non-metals are the least reactive
noble gases
