10 electrons in an atom can have each of the 3d quantum number or sublevel designations.
<h3>What are four quantum numbers?</h3>
Quantum numbers are used to characterize the values of conserved quantities in a quantum system's dynamics in both quantum physics and chemistry.
1) The "n" sign refers to the principal quantum number. It shows how many shells there are.
2) The "l" sign indicates the azimuthal quantum number. It gives the form of the orbitals and their angular momentum. 0 to n-1 make up its range.
3) "
" stands for the magnetic quantum number. It serves as a cue for spatial orientation. The range of it is -l to +l.
4) Spin quantum number, represented by the symbol "
". It shows how the electron is spinning.

Answer:
There are 8.55ₓ10²⁵ atoms of P, in 7.1 moles of Cu₃(PO₄)₂
Explanation:
Copper (II) ⇒ Cu²⁺
PO₄⁻³ → phosphate
3Cu²⁺ + 2PO₄⁻³ → Cu₃(PO₄)₂
1 mol of copper (II) phosphate has 2 mol of P, 8 moles of O and 3 moles of Cu.
Then, 7.10 moles of salt has (7.1 .2) = 14.2 moles of P
In 1 mol we find, NA atoms (6.02ₓ10²³)
In 14.2 moles we would find (14.2 .NA) = 8.55ₓ10²⁵ atoms
Answer:
Sometimes, fires occur naturally, ignited by heat from the sun or a lightning strike. However, most wildfires are because of human carelessness such as arson, campfires, discarding lit cigarettes, not burning debris properly, playing with matches or fireworks.
Answer: the plant, soil, water, sunlight, anything you’re not changing
Explanation:
i’m guessing you’re testing to see if the fertilizer works? so it should be anything but the fertilizer since you would we testing one with and without fertilizer
