SUBATOMIC PARTICLES

After reading this section you will be able to do the following:

<span>List the three main subatomic particles of an atom.Discuss the positions of these particles within the atom and what electric charge they carry, if any.</span>

What are atoms made of?

Now that we have talked about how atoms are combined to make other substances, let's talk about the particles that make up the atom. Particles that are smaller than the atom are called subatomic particles. The three main subatomic particles that form an atom are protons, neutrons, and electrons. The center of the atom is called the nucleus. First, let's learn a bit about protons and neutrons, and then we will talk about electrons a little later.

Protons and Neutrons

Protons and neutrons make up the nucleus of an atom. All protons are identical to each other, and all neutrons are identical to each other. Protons have a positive electrical charge, so they are often represented with the mark of a "+" sign. Neutrons have no electrical charge and are said to help hold the protons together (protons are positively charged particles and should repel each other).

If all protons are identical and all neutrons are identical, then what makes the atoms of two different elements different from each other? For example, what makes a hydrogen atom different from a helium atom? The number of protons and neutrons in the nucleus give the atoms their specific characteristics. In the graphic below you will notice that each of the three elements have different numbers of protons and neutrons. They would also like to have the same number of electrons as they have protons in order to stay electrically balanced.

A sample of helium gas occupies a volume of 152.0 mL at a pressure of 717.0 mm Hg and a temperature of 315.0 K. What will the vo
kozerog [31]

Answer:

0.581 L  or  581 mL

Explanation:

As stated in the question, the combined gas law is (P1*V1/T1) = (P2*V2/T2)

Write down the amounts you are given.

V1 = 0.152 L (I was taught to always convert milliliters to liters)

P1 = 717 mmHg

T1 = 315 K

V2 = ?

P2 = 463 mmHg

T2 = 777 K

The variable that is being solved for is final volume. Fill in the combined gas law equation with the corresponding amounts and solve for V2.

(717 mmHg*0.152 L) / (315 K) = (463 mmHg*V2) / (777 K)

0.346 = (463*V2) / (777)

0.346*777 = (463*V2) / (777)*777

268.842 = 463*V2

268.842/463 = (463*V2)/463

V2 = 0.581

Pressure and volume are indirectly proportional. This checks out because the volume increased while pressure decreased. Volume and temperature are directly proportional. This checks out because both volume and temperature increased. This is a good way to check your answers. You can also solve each side of the combined gas law equation to see if they are both the same.

What is einsteins theory of relativity?
White raven [17]

Answer:

The laws of the universe are for all observers, and it was shown that the velocity of light in spacetime will be the same regardless of the subject's speed.

Explanation:

The principle outlines how things behave in time and space, so it could be used to model anything from black hole life to light shifting due to the gravitational, as well as the action of the terrestrial Planets in its orbit. Einstein's most popular hypothesis has far-reaching ramifications.

Use the drop-down menus to identify each organic reaction as an addition, substitution, elimination, or condensation reaction.
musickatia [10]
First reaction is a Condensation Reaction. As a amall molecule (water) is evolved with the production of ether this is called as condensation of alcohols.

Second reaction is Addition Reaction also known as electrophilic addition reaction. Here HBr is added across double bond to yield alkyl halide.

Third reaction is Elimination Reaction. In this reaction tertiary alcohol is treated with base. A unsaturated compound is formed in this reaction.

Last reaction is Substitution Reaction (Aromatic Electrophilic substitution reaction. In this case a electrophile on benzene (Proton) is substituted with another electrophile (Bromine)
