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.

∙ 11y agoThis is officially called the octet rule. Also note that it should not be taken too literally. Several of the lighter elements, hydrogen, helium, lithium, and beryllium, are at their most stable with two electrons in their outer shell, or in the case of hydrogen, equally stable with no electrons in its outer shell (which reduces hydrogen to a mere proton).

How are both stability and change seen in properties of elements?
Atoms with full octets form stable elements
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.
Is an atom most stable when it has eight electrons in its outermost energy level?
Most Atoms are more stable when they have eight valence electrons. The more electrons, the more stable. So No, most atoms are MORE stable when they have eight valence electrons.
What is duplet rule in chemistry?
According to the Lewis concept, "when two atoms form a covalent bond between them, each of the atoms attains the stable configuration of the nearest inert gas, by completing its "octet" or 8 electrons in the outermost shell, or " duplet" or 2 electrons in the case of hydrogen." In other words, the duplet rule states that when an element gets 2 electrons in its valence or last shell it has achieved a stable electronic configuration . The octet rule states that when an element acquires 8 electrons in the valence shell it becomes stable like the noble gases. Certain elements like lithium and hydrogen do not attain eight electrons in their outermost valence shell.
Why is a stable octet configuration thought to be so stable?
The octet rule is a simple rule of thumb that states that atoms tend to combine in such a way that they each have eight electrons in their valence shells, giving them the same electron configuration as a noble gas. The rule is applicable to the main-group elements. In simple terms, molecules or ions tend to be most stable when the outermost electron shells of their constituent atoms contain eight electrons .

What rule says atoms need to have 8 valence electrons?
All atoms want to have their outer energy levels full. When they have eight valence electrons they are full. They will become full by combining with other elements that the they may encounter until they see eight. You also could say until they have eight valence electrons.
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.
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 are the atoms on the periodic table set up in columns What is so special about their atomic structure Why is Ne in the last column while Li in the first?
The elements were arranged according to atomic number. And atomic number is equal to the number of protons and electrons. There is a rule (octet rule), which states that for an atom to be stable, it needs 8 electrons. The First Group has one excess electron to be stable. Group 7 needs one electron to be stable. (in short... 1-1=0(stable), 7+1=8(stable)) Group 8 has 8. So it is stable, and located at the end of the table.

Sodium and chlorine atoms combine readily because they both tend to lose electrons true or false?
both, since both are one electron short of a stable octet, hence why both are reactive elements. Bond formation is favoured with other elements, though the natural states of the elements are different, group one and seven will b0nd preferentially if poossible.
Area in which electrons are arranged in energy levels?
The area in which electrons are arranged in energy levels is called "Main Energy Levels." The chart also includes configurations of the electrons. I have attached a link to explain.
What rule states that to be stable atoms need 2 valence electrons?
This rule doesn't exist; you think probable to octet rule.
What is the term for an atom whose electrons have the lowest possible energies?
The term for an atom whose electrons have the lowest possible energies is "ground state." In this state, electrons are in their lowest energy levels or orbitals, closest to the nucleus. Excited states refer to when electrons are in higher energy levels, further away from the nucleus.
