POWER-UPday 1

  • What makes metal different than other materials (like wood, ceramics, cloth, etc).

  • List as many ways as possible.


Pre magnetism electricity

PRE-MAGNETISM & ELECTRICITY

A brief overview of atoms And sub-atomic particles


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


There are three types of bonds between atoms ionic covalent metallic

There are three types of bonds between atoms

- Ionic

- covalent

- metallic

Connecting atomsto make objects


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 chemistry1

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.
