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 existAdditionally, 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.

Explain… What are the subatomic particles of an atom, and where are they located in the atom? Be specific.
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).
I hope its helpWhich 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.

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".

What is the quantum mechanical electron configuration of arsenic?
Answers
Answer:
After the 4s sublevel is filled with two electrons, ten electrons fill the 3d sublevel, which is slightly higher in energy than the 4s sublevel. After the 3d sublevel is filled, the remaining three electrons will be in orbitals in the 4p sublevel. Thus, the electron configuration for arsenic is [Ar] 4s(2 squared) 3d(10 squared) 4p(3 squared).

1. What process occurs along divergent plate boundary?
2. What geologic features formed when two plates moved away from each other?
3. Compare rift valley from mid-ocean ridge. Explain your answer. PIVOT 4A CALABARZON 24
Answers
1. Earthquakes and Eruptions (volcanoes)
2. Divergent plate boundary
3. Apart from a widening valley, it equally contributes to steep mountain sides spreading. A mid-oceanic ridge is naturally produced if two oceanic plates naturally start moving away from each other.
Explanation:1. When a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge. Extensional forces stretch the lithosphere and produce a deep fissure. When the fissure opens, pressure is reduced on the super-heated mantle material below. It responds by melting, and the new magma flows into the fissure. The magma then solidifies and the process repeats itself.
2. When two plate diverge from each other also known as divergent (di-apart, vergere- to inclined) plate margin .
Two plate diverge along oceanic ridges where new lithosphere is created.
Now come to the main point: Geological Features
When two oceanic plate diverge then new sea floor is created by a process called sea floor spreading and features like Mid oceanic ridges, volcanoes & Young lava flows forms. Ex. East Pacific Rise, Mid-Adlantic Ridge.
When two continental plates diverge by continental rifting then features like Rift valley, volcanoes are found. Ex of continent continent -East Africa rift vally, Red sea.
3. The major difference between different types is what type of plate the divergent boundary is between. If the boundary is found between two continental plates you are left with a rift valley. ... If two oceanic plates begin moving away from each other it creates a mid-oceanic ridge.
