1. The basic building block of matter are atoms. Every atom is basically a tiny sphere. Every atom is composed of 2 regions, the

outer part of the sphere is called the _______ and accounts for about 99.95% of the volume of an atom. 2. The electron cloud is the region of an atom in which the __________ are found. __________ are tiny particles with a -1 electrical charge and almost no mass. Electricity is _________ flowing though a conductor, usually metal. 3. Every atom is composed of 2 regions. The very tiny center part of the spherical atom is called the _____________. The __________ accounts for about 99.95% of the mass of the atom even though it has almost no volume. 4. Every atom has a nucleus. The nucleus contains 2 different types of particles. The particle with the +1 electrical charge is called the __________. It has almost 2000 times more mass than an electron. The number of __________ in the nucleus determine how many electrons the neutral atom has and all of the chemical reactions the atom can do. 5. Every atom has a nucleus. The nucleus contains 2 different types of particles. The particle with no (0) electrical charge is called the __________. This particle is electrically neutral. The +1 charged protons would repel each other and destroy the nucleus if the _______________ were not neutralizing the repulsive force between the protons. 6. When graphing how the experimental “effect” depends on the experimental “cause”, the graph can show either a _______________ or an inverse relationship or no relationship. If the “effect” (dependent variable) value increases when we make the “cause” (independent variable) value increase, then we call this a ____________________. 7. When graphing how the experimental “effect” depends on the experimental “cause”, the graph can show either a direct relationship or an ______________ or no relationship. If the “effect” (dependent variable) value decreases when we make the “cause” (independent variable) value increase, then we call this an ____________________. 8. When graphing how the experimental “effect” depends on the experimental “cause”, the graph can show either a direct relationship or an inverse relationship or _____________. If the “effect” (dependent variable) value doesn’t change when we make the “cause” (independent variable) value increase, then we call this ____________________. 9. An experiment needs an _________________ to validate its results. The ________________ can be one of 2 things. The __________________ can be a set of experimental conditions we repeat several times throughout the experiment. Or the ________________ can be a set of conditions which other experimenters have used and is considered “normal” or “state of the art.” 10. A variable is something which can change during an experiment. It works best when we only let 2 variables change. All the rest are kept constant and are called _______________. fill in the blanks with these words. Direct relationship ,No relationship ,Proton(s), Neutron(s), Controlled variable(s), Electron(s), Experimental control, Inverse relationship, Electron cloud, Nucleus.

The answers would be:

1. Electron cloud

2. Electrons, Electrons, Electrons

3. Nucleus, nucleus

4. Protons, protons

5. Neutrons, Neutrons

6. Direct, direct.

7. Inverse, inverse

8. No relationship, no relationship

9. Experimental control

10. Controlled variables

Here is more about the question:

An atom has 3 subatomic particles:

Proton: positively charged particles

Electron: Negatively charged particles

Neutrons: Neutrally charged particles

The nucleus is made up of the protons and neutrons, while the electrons are found outside, within the electron cloud.

Electrons are very important in bonding. It is also heavily involved in electricity. Electricity is the flow of electrons through a conductor.

Relationships in a graph:

For direct relationships, you just need to remember, when one goes up, the other one goes up too.

Inverse relationships on the other hand, when one goes up the other goes down.

If no change occurs, then we can say that there is no relationship.

hey you look nice (pic).

According to Newton’s first law, if no force is applied to a ball, it will continue moving at the same speed and direction as it did before. When we put the ball on the grass it stays in its place, namely it stays in zero motion since no force is applied to it. However, after we kick the ball, it will continue moving in the direction we kicked it. Its speed will drop gradually, due to friction (a force applied on the ball in the opposite direction to its motion), but the direction of its motion will remain the same.

According to Newton’s second law, a force applied to an object changes that object’s acceleration – namely, the rate at which the speed of the object changes. When we kick the ball, the force we apply to it causes it to accelerate from a speed of 0 to a speed of dozens of kilometers per hour. When the ball is released from the foot, it begins to decelerate (negative acceleration) due to the force of friction that is exerted upon it (as we observed in the previous example). If we were to kick a ball in outer space, where there is no friction, it would accelerate during the kick, and then continue moving at a constant speed in the direction that we kicked at, until it hits some other object or another force is applied to it.

Korvikt [17]
  • initial velocity=u=0m/s
  • Final velocity=v=4m/s
  • Time=t=0.5s

\\ \sf\longmapsto Acceleration=\dfrac{v-u}{t}

\\ \sf\longmapsto Acceleration=\dfrac{4-0}{0.5}

\\ \sf\longmapsto Acceleration=\dfrac{4}{0.5}

\\ \sf\longmapsto Acceleration=8m/s^2

Which particle would have the slowest rate of deposition? A.round particle B.very large particle C.particle with sharp ends D.pa
lisabon 2012 [21]

The particle with sharp ends have the slowest rate of deposition  

Answer: Option C  

<u>Explanation:</u>

          As per aerosol physics, deposition is a process where aerosol particles accumulate or settle on solid surfaces. Thereby, it reduces the concentration of particles in the air. Deposition velocity (rate of deposition) defines from F = vc, where v is deposition rate, F denotes flux density and c refers concentration.  

          Deposition velocity is slowest for particles of intermediate-sized particles because the frictional force offers resistance to the flow. Density is directly proportional to the deposition rate so clearly shows that high-density particles settle faster. Due to friction, round and large-sized particles deposit faster than oval/flattened sediments.
