POWER-UP day 1
  • What makes metal different than other materials (like wood, ceramics, cloth, etc).
  • List as many ways as possible.
atom definition
Atom Definition
  • Atoms are the basic unit of matter, which consist of a dense inner nucleus and an outer cloud of electrons.
the sub atomic particles
The sub-atomic particles
  • There are 3 sub-atomic particles
  • - Protons
  • - Neutrons
  • - Electrons
positively charged found in the nucleus relatively large mass stationary within a solid object
- Positively charged- found in the nucleus

- Relatively large mass

- Stationary within a solid object

Protons
electrons
Electrons
  • Negatively charged
  • Found orbiting outside the nucleus
  • Virtually no mass
  • Have incredibly high velocities around the nucleus, always moving around
ignore for our class this year not charged in nucleus relatively large mass stationary
-ignore for our class this year

- Not charged

- in nucleus

-relatively large mass

- stationary

Neutrons
we can ignore these for our class pay attention to them in chemistry
We can ignore these for our class.

Pay attention to them in chemistry.

Ionic bonds

We can ignore these for our class.

Pay attention to them in chemistry.

Covalent bonds
metallic bonds

Its described as a “sea of electrons” around the protons.

The electrons freely pass between protons evenly dispersing themselves in the object

This only happens in metals.

Metallic Bonds
when all of the electrons in a metal object have been shifted to one side
When all of the electrons in a metal object have been shifted to one side.Polarized

exit ticket day 1

Please draw a picture of how the electrons move around the protons in a solid metal object

Now draw a picture of how the electrons are dispersed in a polarized metal object.
