Whats the Matter with you
What is matter?
Anything that has mass and volume
protons and neutrons
In the periodic table, elements in the vertical columns form this
Families or Groups
Convert 1200mL to L
1.2 L
two ways to classify matter
mixture or pure substance
What is mass?
It is the amount of "stuff" in an object
number of protons in the nucleus and characteristic of each element
The horizontal rows on the periodic table are called
Periods
Sharing of electrons equally between two atoms
non-polar covalent bond
Difference between elements and compounds
Compounds are made up of two or more elements
The smallest unit of an element is a what?
An atom
Sum of protons and neutrons of an atom
atomic mass
The elements in group 18 are known as the--
What are Metalloids
Has characteristics of both metals and nonmetals
difference between heterogeneous and homogeneous mixtures
Heterogeneous mixtures have visibly different components.
Homogeneous mixtures appear uniform throughout.
What is an element?
A pure substance that cannot be broken down.
isotope
Elements that are good conductors of electricity are called
metals
This type of elements are usually liquids or gases at room temperature
Non-metals
chicken noodle soup is this kind of mixture
heterogeneous
Draw the different formations of atoms in solids, liquids and gases
Solids- tight together
Liquid- more spread apart
gas- far apart.

proton - positive
neutron - neutral
electron - negative
