Explanation:
Formula used for the radius of the orbit will be,
(in pm)
where,
= energy of orbit
= radius of orbit
n = number of orbit
Z = atomic number
a) The Bohr radius of an electron in the n = 3 orbit of a hydrogen atom.
Z = 1
476.1 pm is the Bohr radius of an electron in the n = 3 orbit of a hydrogen atom.
b) The energy (in J) of the atom in part (a)
is the energy of n = 3 orbit of a hydrogen atom.
c) The energy of an Li²⁺ ion when its electron is in the n = 3 orbit.
n = 3, Z = 3
is the energy of an Li²⁺ ion when its electron is in the n = 3 orbit.
d) The difference in answers is due to change value of Z in the formula which is am atomic number of the element..
None
it is a form of electromagnetic radiation, meaning it does not have any protons or neutrons
Is there a picture of the isotope or?- becaue I can’t help if I don’t have a visual.
Answer:
Nucleus and mitochondria. Organism.
Explanation:
The two main organelles are the nucleus and the mitochondria . The nucleus is boss of the factory(controls everything). The mitochondria is the power house of the cell (provides the energy). Humans are organisms (made of organs systems working together) . Another example is plants they are also organisms
Answer:
coeffeicent!
Explanation:
this balances equations and also changes the amount of a compound/element present
