Answer:
The answer to this question would be electron.
Electron is located on the outer side of the atom and constantly moving in an orbit so its location cannot be accurately determined. The cloud around the center of the atom is drawn to picture the orbit.
Neutron and proton located in the middle of an atom in a part that called nucleus. Nucleus location is kept at the center and it doesn't move.

how many significant figures in 1. 19.99 2. 140486 3. 0.0609 3. 5.08 ?
1. 4 significant numbers
2. 6 significant numbers
3. 3 significant numbers
4. 3 significant numbers
Further ExplanationSignificant numbers are numbers obtained from the measurement results of exact numbers and the last number estimated
1. 19.99
all non-zero numbers are significant numbers , so there are 4 significant numbers
2. 140486
a zero which is located between two non-zero numbers including a significant number , so there are 6 significant numbers
3. 0.0609
a zero in front of a decimal point is not a significant number, so there are 3 significant numbers (6,0 and 9)
4. 5.08
Any zeros between two non-zero numbers are significant, so there are 3 significant numbers(5,0 and 8)

Answer:
EASSSSSYYY give me a harder question smh
if you want you can give me Brainliest answer lol
Explanation:
A solid’s particles are packed closely together. The forces between the particles are strong enough that the particles cannot move freely.
A liquid is a fluid that conforms to the shape of its container but that retains a nearly constant volume independent of pressure. The volume is definite (does not change) if the temperature and pressure are constant.
Gas molecules have either very weak bonds or no bonds at all, so they can move freely and quickly. Because of this, not only will a gas conform to the shape of its container, it will also expand to completely fill the container.
If Beryllium has a mass number of 7 and atomic number of 4, how many protons does it have?
Answer:
4
Explanation:
Answer:
4
Explanation:
So the atomic number is still the proton number and it is always smaller than the atomic mass so the proton number is 4.

What is the wavelength, in meters, of yellow light with a frequency of 5.10 x 1014 Hz?
Answer:
5.88 × 10⁻⁷ m
Explanation:
Speed of Light = Wavelength times Frequency
c = λν
Step 1: Define
c = 3.0 × 10⁸ m/s
ν = 5.10 × 10¹⁴ Hz
λ = unknown
Step 2: Solve for λ
3.0 × 10⁸ m/s = 5.10 × 10¹⁴ Hz · λ
λ = 5.88235 × 10⁻⁷ m
Step 3: Simplify
We are given 3 sig figs.
5.88235 × 10⁻⁷ m ≈ 5.88 × 10⁻⁷ m

A:The number of gerbils you feed incorrect answer
B:The amount of candy the gerbils eat incorrect answer
C:The amount of water the gerbils drink incorrect answer
D:The body mass of the gerbils incorrect answer
Answer:
B
Explanation:
the less candy will be the smallest gerbil and the most candy will be the fatest
Answer:
A) The number of gerbils you feed
Explanation:
If you wanted to test whether eating candy made gerbils fat you would need to fluctuate the amount of candy each group receives to observe whether there was any differnce in weight
Write two uses of sublimation process?
Answer:
Explanation:
Practical Applications of Sublimation
Sublimation and erosion cause ablation, a process that wears down glaciers. Sublimation of iodine may be used to reveal latent fingerprints on paper. Sublimation is used to purify compounds. ... Because dry ice sublimates so readily, the compound is used to produce fog effects.

Which of the following can be inferred from the diagram above that shows the dependence of potential Energy on the Internuclear distance between two atoms?
A - The atoms form a bond with a bond length of 25 pm
B - The atoms form a bond with a bond length of 75 pm
с - The net force between the atoms is attractive at 25 pm
D - The net force between the atoms is attractive at 75 pm
Answer:
B - The atoms form a bond with a bond length of 75 pm
From the potential energy diagram of shown, we can infer that the atoms form a bond with a bond length of 75 pm.
When atoms are far away from each other, there exists no interaction whatsoever between the atoms.
However, as the atoms draw closer to each other, the potential energy diagram begins to shift towards an energy minima as we can see from the potential energy diagram.
As the system continues to tend towards this minima, the distance between the atoms decreases. The distance at which the two atoms have the lowest energy is called the bond length.
For this system, such a bond length occurs at 75pm as we can see from the diagram.
