1. Decide which of the following is the best observation.
The dog ate the bone hiding.
The dog ate the bone hiding under the tree.
The dog ate the bone hiding under the shady tree.
The dog ate the bone.

Answers

Answer:

The dog ate the bone hiding under the shady tree.

Explanation:

The best observation is that the dog ate the bone hiding under the shady tree. This is because it provides the most graphic details about the position and activities of the dog.

With this choice, we can properly picture the dog and the relationship it has with the tree. The more information we know about a subject of investigation, the better an observation it affords. Such a well informed observation will make analysis much better.

Answer:

The dog ate the bone hiding under the shady tree.

Which element has 5 protons 5 neutrons and 5 electrons

Answers

Question: which element has 5 protons 5 neutrons and 5 elections






Answer: Boron

Elements are the smallest unit of the atom and cannot be divided. An element having 5 electrons, protons, and neutrons is a boron.

What are subatomic particles?

Subatomic particles are the constituents of atoms that have mass and charge. They are the components that make the element unique and give the atomic number and the mass.

The electron is a negatively charged particle and protons are positive particles that along with neutral neutron give the atomic mass. An element with 5 sub atomic particles is called a boron.

Therefore, the element is boron.

Explain what happens if you change the number of protons in an element?

Plzzz helpppp!!!​

Answers

Answer:

When you change the number of protons in an atom, you will change the atom from one element to a different element. Sometimes, when you add a proton to an element, the element will become radioactive. If you change the number of electrons in an atom, you will get an ion of the element.

For the n = 3 electron shell, which of the following quantum numbers are valid? Check all that apply.

Answers

Answer:

The valid quantum numbers are l=0, l=-2 and l= 2.

Explanation:

Given that,

n = 3 electron shell

Suppose, the valid quantum numbers are

l = 3

m = 3

l = 0

m = –2

l = –1

m = 2

We know that,

The value of n = 3

Principle quantum number :

Then the principal quantum number is 3. Which is shows the M shell.

So, n = 3

Azimuthal quantum number :

The azimuthal quantum number is l.

[tex]l=0,1,2[/tex]

Magnetic quantum number :

The magnetic quantum number is

[tex]m=-2,-1,0,1,2[/tex]

Hence, The valid quantum numbers are l=0, l=-2 and l= 2.
