electromagnetic force
Energy levels or energy shells or orbits
The electrons around the nucleus are grouped into various orbitals.
# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass
The strong force holds the nucleus together against the repulsion between the electric charges of the protons.
The force that holds electrons around a nucleus is the electrostatic force of attraction between the positively charged nucleus and the negatively charged electrons. This force is known as the electromagnetic force and is responsible for keeping the electrons in orbit around the nucleus.
Electrons produce a magnetic force that holds earth together and trees
Yes and it is due to the fact that nucleus is compact while electrons form a cloud around nucleus.
Electrons
s holds 2 electrons (e-)p holds 6 electrons (e-)d holds 10 electrons (e-)f holds 14 electrons (e-)This is true if you mean orbitals and not orbits.
The electrons with the highest energy are an atom's valence electrons. These are the electrons in the outermost energy level, or valence shell, which is the part of an atom that participates in a chemical reaction.
Electrostatic force betweeen positive nucleus and negatively charged electrons.
protons hold electrons around the nucleus. Electrons have a negative charge while protons have a positive charge, so since opposite charges attract each other, electrons and protons hold each other in place.
