What is the rule that states stable elements have eight electrons in their outer levels?
Nonreactive elements like noble gases have 8 electrons in the outermost shell. An element is the most stable when its outermost shell has 8 electron that's is it is completely filled. 8 is the maximum number of electrons which can be accommodated in the outer most shell.
Helium is an exception as it has only 2 electrons in its only shell. Yet it is nonreactive.

Which metal atoms can form ionic bonds by losing electrons from both the outermost and next to outermost principal energy levels?
Transition metals are the ones that can form ionic bonds by losing electrons from both the outermost and next to outermost principal energy levels. This is because transition metals have multiple oxidation states due to the presence of partially filled d-orbitals. By losing electrons from different energy levels, these metals can achieve a stable configuration.
How are both stability and change seen in properties of elements?
Atoms with full octets form stable elements
Are atoms of group 16 elements more likely to gain or lose electrons?
Atoms of group 16 elements are more likely to gain electrons because they have 6 valence electrons and need 2 more to achieve a stable octet configuration, which is typically done by gaining electrons rather than losing them.
Elements of the same group on the periodic table have the same number of what?
electron shells/engery levels all of the elements in period one have one electron shell/engery levels all of the elements in period two have two electron shells/engery levels etc.
Why do covalent bonds not involve the transfer of electrons?
Covalent bonds involve the sharing of electrons between atoms, rather than the transfer of electrons like in ionic bonds. In a covalent bond, the atoms mutually share electrons to achieve a more stable electron configuration.
Do electrons in stationary states emit the most radiation?
No, electrons in stationary states do not emit radiation because they are in stable energy levels. Radiation is emitted when electrons transition between energy levels, releasing photons of specific energies.

Does the presence of an octet makes an atom very likely to react with other elements?
Yes, atoms with an octet are stable and less likely to react with other elements because they have a full outer shell. Octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell, making them more stable.
What rule says atoms need to have 8 valence electrons?
The octet rule states that atoms tend to gain, lose, or share electrons in order to have a full outer shell of 8 electrons, which is a stable configuration. This is known as the octet rule because it applies to the first 20 elements in the periodic table, which aim to achieve a full valence shell similar to the noble gases.
What element is likely to follow the duet rule?
You probably mean the octet rule, which states that atoms undergo chemical bonding in order to achieve an octet (8) of electrons in their valence shell. This makes them stable. All of the main group elements follow this rule, except for hydrogen. It is stable with two valence electrons. The main group elements are Groups 1, 2, and 13-18.
How does the octet rule determine the lose or gain of electrons by representative elements?
The octet rule states that atoms tend to gain, lose, or share electrons in order to have a full outer shell of 8 electrons, like the noble gases. Representative elements either gain or lose electrons to achieve this stable electron configuration, becoming ions with a charge that corresponds to the number of electrons gained or lost.
In many compounds atoms of main group elements form ions so that the number of electrons in the outermost energy levels of each ion is?
In many compounds, atoms of main group elements form ions so that the number of electrons in the outermost energy levels of each ion is 8 (or 2 for hydrogen and helium). This is known as the octet rule, which states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of electrons, similar to the noble gases.
Are atoms of group 16 elements more likely to gain or lose electrons?
Atoms of group 16 elements are more likely to gain electrons because they have 6 valence electrons and need 2 more to achieve a stable octet configuration, which is typically done by gaining electrons rather than losing them.
How does the octet rule relate how active an element is?
The octet rule states that all elements form ions to reach 8 valance electrons, or the nearest noble gas. If an element is a noble gas, it already has 8 valance electrons, therefore does not need to form ions to bond with other ions, thus becoming un-reactive.
Elements of the same group on the periodic table have the same number of what?
electron shells/engery levels all of the elements in period one have one electron shell/engery levels all of the elements in period two have two electron shells/engery levels etc.
