In orbitals and shells. Orbitals are hard to describe because they are shaped by relativistic quantum mechanics and can only be visualized as probability clouds not as physical shapes. Shells are composed of sets of orbitals.
s orbital probability clouds are spherical.
p orbital probability clouds are egg shaped ellipsoids.
d orbital probability clouds are hour glass shaped with a donut around the middle unattached.
f orbital probability clouds are hour glass shaped with two distorted donuts around the middle unattached.
etc.
Shell 1 has a single s orbital.
Shell 2 has a single s orbital and 3 p orbitals.
Shell 3 has a single s orbital, 3 p orbitals, and 5 d orbitals.
Shell 4 has a single s orbital, 3 p orbitals, 5 d orbitals, and 7 f orbitals.
etc.
No. Atoms have the same number of protons and electrons. When atoms gain or lose electrons they are called ions.
to become stable
The Outermost Electrons are the reactive particles of the atoms.
Electrons shared between atoms.
hydrogen atoms share electrons when it forms covalent bonds
Electrons are smaller than atoms. There are electrons in atoms, but no atoms in electrons.
yes, some atoms don't actually have electrons.
Atoms share electrons when they form covalent bonds.
Yes, free electrons can collide with atoms.
No. Atoms have the same number of protons and electrons. When atoms gain or lose electrons they are called ions.
Atoms transfer electrons, then bond.
Atoms which form covalent bonds do share electrons. An example would be the atoms in a water molecule. Yes, the electrons are really shared.
The two atoms share their electrons.
A covalent bond forms when atoms share electrons.
Carbon atoms have 6 electrons, when non-ionized
Your body is made of molecules which are made of atoms. All atoms have electrons.
