protons positive electrons negative neutrons neutral
electrons are on the outside and don't count as part of the atomic mass. Protons do count as part of the mass and are inside the atom.
The smallest part of an element that still retains its properties is an atom.
The atom would stay the same size because it would still have the same amount of energy levels. The mass of the atom would be slightly less though.No, an atom shrinks when loosing an electron.There are less electrons ('-'charges) left that are attracted by the same number of protons ('+'charges) in nucleus, so the atraction per electron is stronger.
The smallest part or fragment of an atom is the Electon.
The nucleus of an atom is the densest part of an atom. It contains the protons and neutrons of an atom.
Proton: positive charge Electron: negative charge Neutron: neutral
Protons are the positively charged particles located in an atom's nucleus.
By adding the neutrons and the protons together, as the electrons are such a small part of the atom it does not matter.
The nucleus contains the majority of the mass in an atom. The nucleus contains the protons and neutrons, which each have a relative mass of 1 amu. The electrons surround the nucleus and have a relative mass of 0 amu.
In the nucleus der....
Positive. The only (typical) parts of atoms that move are electrons which have a negative charge; therefore, if a neutral atom loses an amount of electrons (negative charges), the atom has more positive charges (from the protons) than negative charges which makes the atom positively charged overall.
Relative amounts of each part of a whole
The name helium tells that its atomic number is 2, containing 2 protons in each atom. The numerical part of the name shows that each atom also has one neutron.
1/1840 the mass if a hydrogen atom.
Neutron= neutral Protons=positive Electrons=negative
no an atom is a part of a molecule.
