Atoms gain, share, or lose electrons to try and become more stable. Atoms will gain, share, or lose electrons until they have a stable 8 valence electrons in their outer shell which is called an octet, which is stated in the octet rule. See the attached links for information on the octet rule.
Because they don't have a full outer shell of electrons, 2,8,8,18
they share electrons
Since platinum is a metal it will tend to lose electrons.
What are charged particles that form when atoms gain or lose electrons
Atoms with eight valence electrons usually do not gain or lose electrons. Atoms with one, two, or three valence electrons will lose electrons.
Covalent bonds do not gain or lose electrons, but rather share electrons.
When atoms lose and gain electrons, an ionic bond will form. When atoms share electrons, a covalent bond will form.
To form a molecule, atoms can share, lose, and gain electrons
This depends on the electronegativity of atoms.
they share electrons
Some atoms lose electrons, some gain electrons, and some share electrons depending on what elements are involved and what compound is forming.
do atoms of a covalent bond lose r share electrons
No. Atoms can gain and lose electrons but seldom gain or lose protons.
A completely filled shell of electrons has 8 electrons.
Atoms gain lose or share valence electrons in a way that makes the atoms more stable
When atoms lose or gain electrons, they form ions. These are charged particles.
They gain or lose electrons, while the atoms combine.
Since platinum is a metal it will tend to lose electrons.
