What is the difference between ionic and covalent bonding?

Chemistry
1 answer:
mr Goodwill [35]3 years ago
8 0

In an ionic bond, one atom essentially donates an electron to stabilize the other atom. The atoms in an ionic bond have different electronegativity values from each other.

While in a covalent bond, the atoms are bound by shared electrons and the electronegativity values are the same.

In the animation, you can see that the electrons occupy different orbitals according to the energy level of each orbital. A sing
lara31 [8.8K]

B) The He atom has two electrons that have parallel spin in its 1s orbital.

C) Electrons generally occupy the lowest energy orbital first.

D) The arrangement of the orbitals is the same in a multielectron atom and a single-electron atom

E) The C atom has two unpaired electrons.

Explanation:

In writing sublevel notations certain rules are followed:

  • The maximum number of electrons in the orbitals of sublevels are:

             two for s-sublevel with one orbital

             six for p-sublevel with three orbitals

             ten for d-sublevel with five orbitals

             fourteen for f-sublevel with seven orbitals

  • Aufbau's principle states that sublevels with lower energies are filled before those with higher energies.

                    1s 2s 2p 3s 3p 4s 3d 4p 5s    increasing order of filling

  • Pauli exclusion principle states that no two electrons can have the same set of the four quantum numbers i.e electrons in the same orbital cannot spin in the same direction.
  • Hund's rule states that electrons go into degenerate orbitals singly first before pairing up.

Based on these principles and the animation, the following options are correct:

B) The He atom has two electrons that have parallel spin in its 1s orbital.

Helium has two electrons in the 1s orbital. From Pauli's exclusion principle, we see that the two electrons cannot spin in the same way. Therefore, they have parallel spin

C) Electrons generally occupy the lowest energy orbital first.

From Aufbau's principle, electrons go into orbitals with lower energies first before those with higher energies.

D) The arrangement of the orbitals is the same in a multi-electron atom and a single-electron atom

                  1s 2s 2p 3s 3p 4s 3d 4p 5s

Orbitals are arranged in the order of their energies from the lowest to the highest.

E) The C atom has two unpaired electrons.

Which fossil fuel has the least amount of carbon dioxide released in the air each year
Natali5045456 [20]

The correct answer is - natural gas.

The natural gas is the fossil fuel that releases the least amount of carbon dioxide in the atmosphere. It actually releases very little to none. The reason for that is that the natural gas is a fossil fuel which has the methane as its main ingredient. Even when used, it is not causing some serious pollution, instead the pollution comes from not well managed infrastructure and movement from one place to another of the natural gas. The biggest problem, pollution wise, comes from the leaking of the natural gas, when methane is released into the atmosphere.

KOH (aq) + Fe(NO3)3 (aq) →
atroni [7]

Answer:

see below

Explanation:

1. Predicting products (double replacement): ab + cd ---> ad + cb

KNO₃(aq) + Fe(OH)₃(s)

2. balance the equation

3KOH (aq) + Fe(NO3)₃ (aq) ---> 3KNO₃(aq) + Fe(OH)₃(s)

3. I don't know if you need this but ionic equation: only aqueous things get split into ions; gas, liquid, and solids stay together

3K⁺(aq) + 3(OH)⁻(aq) + Fe³⁺(aq) + 3NO₃⁻(aq) ---> 3K ⁺(aq) + 3NO₃⁻(aq) + Fe(OH)₃(s)

removing things on both product and reactant side

3(OH)⁻(aq) + Fe³⁺(aq) --->Fe(OH)₃(s)
