pt1 matter and the periodic table

What is matter

Matter is everything that has mass and takes up space; it can be gas, liquid, or solid

What is mass

Mass is how we measure the amount of stuff, or matter, there is in something

All matter whether BLANK, BLANK, or BLANK is made up of BLANK

Gas, liquid, or solid. Atoms

a BLANK is defined by the number of protons in an atom’s nucleus which gives the atom certain properties

Element

What is the smallest unit of matter

Atom

Matter cannot be BLANK beyond the level of the BLANK with out changing it BLANK

Broken down. Atom. Properties

what is not matter (even though there is more just one answer)

Rainbow-a rainbow is light bouncing off of each other.

A BLANK is defined by the number of protons in an atoms nucleus which gives the atom certain properties

Element

The term BLANK is also defined as a substance consisting entirely of one specific type of atom

Element

What is the element helium (not in the periodic table)

A pure substance and cannot be broken down

This gas is made up of small particles: atom

These atoms all contain only 2 protons in their nucleus which identifies then as the element helium

Pure helium gas consists of only helium atoms

What are atoms made of

Subatomic particles

At the center of every atom, there is a positively charged BLANK

Nucleus

What particles are inside a nucleus

Proton(s) and neutron(s)

BLANK are positively charged particles and BLANK are neutral particles

Protons. Neutrons

Protons and neutrons have the same what?

Mass (it’s super small btw)

The special unit of measurement that is for super small masses is?

Atomic Mass Unit (AMU) [some times called a dalton(?)]

Protons and neutrons of a mass of??

1 AMU

What makes up the majority of an atom

The nucleus

Elections

Elections are negatively charged and orbit the atom’s nucleus. The have around 1/2,000 AMU

What makes up the surface of an atom and are important for how an atom interacts with other atoms

Electron

Electron are primarily responsible for the BLANK the BLANK can be involved in

Chemical reactions. Atom

One negatively charged BLANK can cancel out on positively charged BLANK

Electron. Proton.

Neutral atoms of an equal number of what?

Protons and electrons (# of +charged particles = # of -charged particles) so they valence each other out and there is no net charge on the atom, and also (protons=electrons)[for neutral atoms]

When an atom loses an electron and is no longer neutral it is the called a/an what?

Ion
