Elements and the Periodic Table

Atoms

100

This is the positively charged particle found in the nucleus of an atom 

What is proton

200

This is the particle found in the nucleus that does not have a charge 

what is the neutron 

300

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 

400

When a scientist uses a diagram or an object to explain the structure of atoms, the scientist is using this

A model 

500

element that contain equal numbers of protons but different numbers of neutrons in their nuclei are this

isotopes 

The Periodic Table

100

Horizontal rows in the periodic table are called 

Periods 

200

vertical columns of the periodic table are called  

Groups 

300

Dmitri Mendeleev found there was a pattern to the properties when elements were arranged in order of increasing this

atomic mass

400

This is the group of elements located along a zig zag line in the periodic table

Metalloids 

500

Elements located to the right of the "staircase" are these

nonmetals 

Properties

100

This is the ability to reflect light 

shininess 

200

This is the ability to conduct heat or electricity 

conductivity 

300

This is the ability to be hammered, pressed, or rolled into thin sheets

malleability 

400

Chemical property in which a metal undergo destruction in the presence of another substance. 

Corrosion 

500

Chemical property which measures how easily an element will combine with other elements to form compounds

reactivity 

Synthetic Elements & Diatomic Elements

100

This super machine is used to make synthetic elements

particle accelerators 

200

This is a gas-like state of matter consisting of high energy electrons that have been stripped away from the atom

plasma

300

These are elements that form molecules consisting of two atoms bonded together.

diatomic elements 

400

This is the most abundant element on earth and is rarely found alone in nature, it is commonly found with oxygen in water. 

Hydrogen 

500

This process occurs when  two or more atomic nuclei are combined to form one atomic nuclei 

nuclear fusion 

Metals and non-metals .

100

Alkali metals can be found in this group of the periodic table

group 1

200

Metals such as iron, copper and gold can be found in this group 

transition metals 

300

Alkaline earth metals can be found in this group

group 2

400

This group of non-metals are the most reactive 

halogens

500

This group of non-metals are the least reactive

noble gases
