Ch1

1 - Moving in straight lines emitted from the negative pole towards the positive pole. 2 - It consists of particles with a very tiny mass and moving very fast. 3 - Affected by the electric field and attracted towards the positive electrode Which indicates it’s a negative charge. 4 - Affected by the magnetic field 5 - Ionize the medium in which it passes.

1 -Attracted towards the negative pole, which confirms that it is positively charged . 2- It has mass and speed which indicates that it is matter particles and are usually heavier than electrons and its mass depends on the type of gas presents in the electric discharge tube. 3- Affected by electric and magnetic fields.

The number determines the shape of the electronic cloud in that probably having an electron around the nucleus for each one principle or more level of the secondary level are s0 p1 d2 f3

The number determines the direction of the orbital around the nucleus and shows the most probably for a position in any exists orbital one orbital more

the number determines the angular momentum of the electron rotation movement is either toword a clockwise direction or anticlockwise
