Why are some elements more stable than others?
They have a stable number of electrons and do not need to react with other atoms. All other atoms have less stable electron numbers, so they react with each other and share electrons to be more stable.
Which elements are stable on their own and why?
The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold.
Why some elements are stable?
An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom’s nucleus may result from an excess of either neutrons or protons.
Are elements more stable in compounds?
Why Atoms Combine – Atoms want to be stable. A stable atom is a happy atom! – Compounds are more chemically stable than the elements from which they were made.
Are atoms more stable when combined?
Atoms form chemical bonds to make their outer electron shells more stable. The type of chemical bond maximizes the stability of the atoms that form it. Covalent bonds form when sharing atoms results in the highest stability.
Why are some elements stable on their own while others are more stable in compounds quizlet?
Terms in this set (5) why are some elements are stable on their own while others are more stable in compounds. Is because some elements need to share and receive electrons in order to be stable. When one atom shares its electrons or protons with another atom which forms a compound.
Why are heavier elements unstable?
The secret is in the very heavy elements made in supernova explosions. Many of the elements heavier than lead have nuclei so large that they are fairly unstable. Due to the instability, over time they eject a neutron or proton, or a neutron in the nucleus decays into a proton and electron.
Why are ionic compounds stable?
Ionic compounds are stable due to presence of strong electrostatic force of attraction between two ions.
What are 2 ways that atoms can combine to become more stable in compounds?
Two processes by which elements can combine to form stable compounds are transferring electrons from one atom to another (ionic compounds) or by sharing electrons (covalent compounds).
Why is lower energy more stable?
Answer: From chemical point of view, a molecule will be stable if there are more attractive forces and less repulsive forces. Repulsive forces increases the potential energy of the molecule. Hence molecules with lower energy are more stable.
Do oxygen atoms become more stable or less stable when oxygen forms compounds?
Do oxygen atoms become more stable or less stable when oxygen forms compounds? They become more stable because they gain or share valence electrons giving each oxygen atom a set of 8 valence electrons. They change because the number of valence electrons changes in a pattern that repeats in each period.
