You tell us the official size of a "pat" and we will give you an answer.
The size of atoms has most to do with its electrons. The electron is a subatomic particle with a negative elementary electric charge.
The semi-major axis (size) and the eccentricity (shape).
all atoms are generally the same size, so "large atoms" would mean molecules.
Yes
they tell us if the substance is stable or not
Tells us there are 2 phosphorus atoms and 5 oxygen atoms
yes atoms do double in size however atoms in helium are smaller because oxygen atoms double in size.
Atoms in the same group have similar structures.
Temperature is related to the average energy per particle.
Matter is neither created nor destroyed. Only change of bonds occur in atoms.
Atomic models tell us about the structure of an atom which is based on what we know about how atoms behave. But it is not necessary that it will be a genuine picture of the structure of an atom.
atomic mass is the no. of protons+no. of nuetron
is it true the size of a mmole of atoms has a reasonable mass
From left to right in a period the size of the atoms decreases.
The shape of a cell may give us a clue about the function of the cell.
