1. Which of the following is neutrally charged?
c. an electron
b. a compound d. a proton
a. an ion
d. a proton

Answers

Answer:

B. A compound

Explanation:

An ion is defined as a charged particle, so it's not going to be that. Ions can be positively or negatively charged.

Electrons are tiny particles, smaller than an atom, that revolve around the nucleus. They have a negative charge. So they are not neutral either

Protons are also a part of atoms, like electrons are. An atom is neutral overall. This is because protons have a positive charge that balances out the negative charge of electrons.

So, the only answer option we have left is for a compound. So, that's our answer!

Answer:

c. an electron

Explanation:

A neutral charge is the electrochemical occurrence where an atom has an equal number of electrons and protons. Such an atom is neither positively charged nor negatively charged because the protons and electrons balance each other out

A lunar eclipse occurs at night and can only occur during what phase of the moon?

New moon

Full moon

Answers

Answer:Full moon

Hope this helps :)

A lunar eclipse can occur only at full moon.

Explanation:

During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. A total lunar eclipse occurs when the Moon and Sun are on opposite sides of Earth. A partial lunar eclipse happens when only part of Earth's shadow covers the Moon.

Answer:

"Full moon"

A full moon would be needed due to the fact that the sun would need to entirely block it, resulting in a solar eclipse. Hence, the answer is "Full moon".

Answers

Atomic Particles

Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

List two differences between a map and a giobe

Answers

Answer:

1. A map is two dimensional, while a globe is three dimensional

2. A globe is a scaled down representation of the entire Planet Earth. A map can represent an area of any size.

Explanation:

1. A map is usually a sheet of rectangular paper that is a flattened image of an area as seen from the top. A globe on the other hand is a sphere which is a 3D shape.

2. Earth is in the shape of a sphere, so Globes are a smaller representation of the planet. A map can be for a city, state, country, or the world.

If an ionic compound has a 2- charge how does that affect the total number of electrons in a Lewis structure

Answers

In the situation where an ion has a charge of -2, the Lewis structure is affected because it must add two additional electrons.

The Lewis structure is a term to refer to the graphical representation that shows the pairs of electrons in dashes or points of bonds between:

The atoms of a moleculeThe lone electron pairs that may exist

Additionally, the charge of an ionic compound is calculated using the difference in electrical charge between the electrons. On the other hand, an ion is formed by adding or removing electrons, so the magnitude of the resulting charge depends on the number of electrons added or removed.

According to the above, if an ionic compound has a -2 charge, the Lewis structure must add two electrons.

Which of the following atoms would be expected to be diamagnetic in the ground state?
O magnesium (Mg)
O potassiun (K)
O chlorine (CI)
O cobalt (Co)

Answers

The atoms that would be expected to be diamagnetic in the ground state is  magnesium

The magnetism of an atom refers to its electronic configuration. A diamagnetic atom is an atom whose electrons are all paired.

A paired electron is an electron that occurs in pairs in its orbital shell.

At their respective ground state, the electronic configuration of the given elements are as follows:

The electronic configuration of magnesium is 1s²2s²2p⁶3s².  As such its a diamagnetic atom.

The electronic configuration of Potassium is 1s²2s²2p⁶3s²3p⁶4s¹. Hence, Potassium has one unpaired electron in its outermost shell.

The electronic configuration of Chlorine is 1s²2s²2p⁶3s²3p⁵. Hence, Chlorine has one unpaired electron in its outermost shell.

The electronic configuration of Cobalt is 1s²2s²2p⁶3s²3p⁶3d⁷4s². Hence, the unpaired electrons of Cobalt in its outermost shell are three.

Therefore, the atoms that are diamagnetic in the ground state is magnesium.
