Answer:
Charge is caused by a flow of electrons, since electrons are around the nucleus they can be lost or gained by atoms. When an atom gets charged, it gains a charge, that is, it gains an electron. Since electrons are negatively charged, when an atom gains one, it also becomes negatively charged.
Answer:
iron (III) oxide =Fe2O3
iron(III) carbonate =Fe2(CO3)3
For the atom to be neutral, it must have the same number of electrons and protons. The aromic number indicates the number of protons. Since Carbon has 6 protons, it would have to have 6 electrons for it to be neutral
Answer:
n is the principal quantum number, it specifies the energy and average distance from the nucleus
l is the orbital quantum number, it specifies the subshell/orbital shape
ml is the magnetic quantum number and specifies the orbital orientation
Explanation:
The Schrödinger wave equation is solved for the hydrogen atom to yield three sets of quantum numbers.
The principal quantum number corresponds to the energy level in the Bohr model and also shows the average distance of the electron from the nucleus.
The orbital quantum number reveals the subshell where an electron is found as well as the shape of the orbital. E.g p-orbitals are dumbbell shaped.
The magnetic quantum number shows the orientation of an orbital in space. Its values range from -l to +l
Answer:
The orbital shapes are actually representation of (Ψ)2 all over the orbit simplified ... ψnlml(r,θ,ϕ)=Rnl(r)Ymll(θ,ϕ) , ... and thus it is directly linked to the angular and radial nodes. ... for different quantum values(which can be assigned to different orbitals are ) .... The two types of nodes are angular and radial.
