-Since 1932, the atomic theory has been further enhanced by the concepts that protons and neutrons are made of even smaller units called _________
-Everything in the universe (except energy) is made up of ______________________ .
-Therefore everything in the universe is made up of ___________________.
-An atom itself is made up of three tiny kinds of particles called subatomic particles: ___________,
________________ and __________________ .
The protons and the neutrons make up the ________________ called the nucleus.
The _____________________ fly around above the nucleus in a small cloud.
The electrons carry a ________________ charge and the protons carry a ___________________charge.
In a normal (neutral) atom the number of protons _____________________ the number of electrons.
Answer:
-Why is Democritus important with regard to atomic theory? Democritus developed his atomic philosophy as a middle ground between two opposing Greek theories about reality and the illusion of change. He argued that matter was subdivided into indivisible and immutable particles that created the appearance of change when they joined and separated from others.
-Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.
-What subatomic particle did JJ Thomson discover? He discovered the electron in 1897.
-In 1913, Neils Bohr proposed a new atomic model known as the Bohr's model, which is patterned after the solar system.
- List the principles of Bohr's model:
a. An electron moves around the nucleus in a circular orbit.
b. An electron's angular momentum in the orbit is quantisized.
c. The change in an electron's energy as it makes a quantum jump from one orbit to another is always accompanied by the emission or absorption of a photon.
- In 1926, Erwin Schrödinger used mathematical equations to describe the likelihood of finding an electron in a certain position. This model is known as the Rutherford Model of an atom.
-In 1932, James Chadwick discovered the neutron.
-Since 1932, the atomic theory has been further enhanced by the concepts that protons and neutrons are made of even smaller units called quarks. The quarks themselves are in turn made of vibrating strings of energy.
-Everything in the universe (except energy) is made up of matter.
-Therefore everything in the universe is made up of atoms.
-An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons and electrons.
The protons and the neutrons make up the centre called the nucleus.
The electrons fly around above the nucleus in a small cloud.
The electrons carry a negative charge and the protons carry a positive charge.
In a normal (neutral) atom the number of protons is the same number of electrons.

Answer:
1A. Half jump
1B. 2/3 is half of 4/3
2. 4
Step-by-step explanation:
1A. The remainder of 2/3 is shown in the model by a half jump. It is a half jump because a full jump is 4/3.
1B. We know that the remainder represents 1/2 of the jogging loop because 2/3 is half of 4/3.
2. Convert 2 1/2 into a mixed number with the denominator as eighths. We then get 20/8 divided by 5/8. After that, we can see that 5/8 goes into 20/8 4 times. (5/8 + 5/8 + 5/8 + 5/8 = 20/8)

Again, I need help with another problem...(I'm going to post 2 more DIFFERENT problem after this one is answered)
Answer:
y = 4x + (-9)
Step-by-step explanation:
You can observe that the line crosses the y-axis at -9, so that is our y-intercept.
For the slope, just take the y-intercept for example, and count how many squares the line goes up before reaching 1. In this problem you can see that the line goes 4 squares up in the time it takes to go 1 square to the right, so the slope is y over x, meaning 4 over 1, or just 4.
Answer:
The answer should be y = 4x + (-9).

Answer:
152%
Step-by-step explanation:
There are 50 small squares total, 25/25 are filled in for the 1st big square, and 13/25 filled in for the 2nd big square.
25/25 + 13/25 = 1.52
1.52 * 100 = 152%
To be consistent with the mystery theme, a local movie theater reported the attendance at their mystery movie festival in the form of a problem to be solved. The report stated the following: “If there were 2 times more adults plus an additional 86 adults, a total of 638 adults would have been in attendance.”
Refer to the information above. If twice as many children as adults attended the festival, then how many children attended the mystery movie festival?

Which number sentence represents the Commutative Property of Addition?
44 + 1 = 45
44 + 1 = 45
(16 + 2) + 18 = 16 + (2 + 18)
(16 + 2) + 18 = 16 + (2 + 18)
56 + 0 = 56
56 + 0 = 56
32 + 9 = 9 + 32
The number which represent represents the Commutative Property of Addition will be;
⇒ 32 + 9 = 9 + 32
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expressions are,
44 + 1 = 45
44 + 1 = 45
(16 + 2) + 18 = 16 + (2 + 18)
(16 + 2) + 18 = 16 + (2 + 18)
56 + 0 = 56
56 + 0 = 56
32 + 9 = 9 + 32
Now,
We know that;
The rule of the Commutative Property of Addition is,
⇒ a + b = b + a
Hence, The correct number which represents the Commutative Property of Addition is,
⇒ 32 + 9 = 9 + 32
