2. Atoms are solid, homogeneous, indestructible, and indivisible.
3. Different kinds of atoms have different sizes & shapes.
4. Size, shape, and movement of atoms determine the properties of matter.]]> 2020-10-05 21:27:54 UTC https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/804822633 flarios32465 https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/804840303 1. Everything is matter and empty space cannot exist.
2. Matter is made of earth, fire, air, and water.
3. Matter can be broken into infinitely small pieces.]]> 2020-10-05 21:39:08 UTC https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/804840303 flarios32465 https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/804848635 1. Matter is composed of extremely small particles called atoms.
2. Atoms are indivisible and indestructible.
3. Atoms of a given element are identical in size, mass, and chemical properties.
4. Atoms of a specific element are different from those of another element.
5. Different atoms combine in simple whole-number ratios to form compounds.
6. In a chemical reaction, atoms are combined or rearranged to form different substances.]]> 2020-10-05 21:44:26 UTC https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/804848635 flarios32465 https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/808344431 1. Atoms consists of mostly empty space through which electrons move.
2. An atom's positive charge and mass can be found in the center of the atom, a dense area called the nucleus.
3. The positive charge of a nucleus balances the negative charge of electrons.]]> 2020-10-06 20:31:46 UTC https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/808344431 flarios32465 https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/808385112 1. The atom has a spherical shape which is composed of a uniformly distributed positive charge.
2. Individual negative charged electrons can be found inside of the atom.]]> 2020-10-06 20:50:02 UTC https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/808385112 flarios32465 https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/808408457 1. Cathode rays were streams of charged particles which carried a negative charge.
2. Radiation's negative particles can be found in all types of matter. These particles are known as electrons.]]> 2020-10-06 21:01:49 UTC https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/808408457 flarios32465 https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/808433860 1. Particles in radiation have a negative charge.
2. The mass of a charged particle is less than that of a hydrogen atom, the lightest known atom.
3. Atoms can be made divisible into smaller subatomic particles.]]> 2020-10-06 21:14:48 UTC https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/808433860 flarios32465 https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/811885123 1. The charge of an electron is 1.592 × 10^-19.
2. The mass of an electron is 1/1840 of a hydrogen atom.]]> 2020-10-07 21:04:23 UTC https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/811885123 flarios32465 https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/811938666 1. The nucleus contains neutrons within it.
2. A neutron has a mass nearly equal to that of a proton and carries no electric charge.]]> 2020-10-07 21:35:11 UTC https://padlet.com/beaumontunified/54b6nqnt918l7oyl/wish/811938666
