Ap sublevel has 3 electrons. How should they be arranged

Chemistry

1 answer:

inna [77]2 years ago

8 0

Answer:

If a sublevel p has 3 electrons, all electrons are in the first p orbital .

Explanation:

According to the rules for establishing the energy level of an element, the sublevel "p" has a capacity for 6 electrons, so a sublevel p with 3 electrons will accept all of those electrons.

An example is nitrogen, with Z = 7, whose electronic level can be written

1s²2s² 2p³

- Two electrons on level 1 sublevel s

- Five electrons on level 2, of which two are in sublevel s and three in sublevel p.

The other options are incorrect:

A and C. It is not possible, because p accepts up to 6 electrons.

D. All sublevels "s" accept up to two electrons, with the exception of hydrogen (z = 1) which has only one electron in the first sublevel s 1s¹.

Answer:

1) rusting of metal is both chemical and physical change

2) black ice is an example of a physical change

Explanation:

when metal rusts, it is due to a reaction between the atoms in the metal and the atoms in the air(oxygen) or water(oxygen). When it rusts it also physically changes the look of the metal from silver to dirty brownish maroon.

Black ice is a change in state hence it cannot be a chemical change as the original substance NO LONGER EXISTS in a chemical reaction. It is a physical change however as the ice is changing into a different state of matter.

How many molecules of CO2 at standard temperature and pressure in 5.4 moles of CO2

olganol [36]

Answer:

3.25×10²⁴ molecules.

Explanation:

From the question given above, the following data were obtained:

Number of mole of CO₂ = 5.4 moles

Number of molecules of CO₂ =?

The number of molecules of CO₂ in 5.4 moles can be obtained as follow:

From Avogadro's hypothesis,

1 mole of CO₂ = 6.02×10²³ molecules

Therefore,

5.4 moles of CO₂ = 5.4 × 6.02×10²³

5.4 moles of CO₂ = 3.25×10²⁴ molecules

Thus, 5.4 moles of CO₂ contains 3.25×10²⁴ molecules.

Select all of the BENEFITS of a PARALLEL circuit. If one bulb burns out the rest of the bulbs will stay lit. The bulbs do not ge

artcher [175]

Answer:

The first two options are correct

Explanation:

The first two options are part of the benefits of a parallel connection of bulbs in a circuit. Here, the voltage of each connecting bulb is the same as the voltage of the bulb in the circuit hence all the bulbs have the same voltage running through them. Thus, when one bulb is removed/burns out, it does not affect the remaining bulbs (those ones will remain lit). Also, the addition of bulb(s) does not cause the remaining bulbs in the circuit to get dimmer (since they will all have the same voltage).

How many electrons would be found in the Ion who’s symbol is I-

Vesnalui [34]

Answer:

Explanation:

Given symbol of the element:

I⁻

Number of electrons found in an ion with the symbol:

This is a iodine ion:

For an atom of iodine:

Electrons = 53

Protons = 53

Neutrons = 74

An ion of iodine is one that has lost or gained electrons.

For this one, we have a negatively charged ion which implies that the number of electrons is 1 more than that of the protons.

So, number of electrons = 53 + 1 = 54

The number of electrons in this ion is 54
