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.
What is bohr model quantum theory?
Bohr's theory is a theory that just states An early model of atomic structure, in which electrons circulate around the nucleus in discrete, stable orbits with different energy levels. This model was the first to predict and explain the atomic spectrum of the hydrogen atom, which arises as the electron jumps from one orbit to another orbit of lower energy, giving off electromagnetic radiation of predictable frequencies. Later models of atomic structure abandoned the idea of circular orbits, and explained the stable orbits as standing waves. Hope this helped, My name is, Estela this is wrong this is Thompson theory Where did you get these answers? These are really good.
When atoms are forming chemical bonds they are trying to reach what configuration?
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.
Why are cuprous ions less stable than cupric ions?
due to its oxidation states or simply the explanation is in the ground and excited states of an atom
What is the use of a Visa electron card?
The use of a Visa electron card is to be able to transfer money and is all around the world except Australia, Canada, Ireland and the United States. The Visa electron card was introduced in the 1980's.

How are both stability and change seen in properties of elements?
Atoms with full octets form stable elements
How does the quantum mechanical model of the atom describes the electron structure of an atom?
The Quantum Mechanical model of the atom states that the location of the electrons around the atom cannot be precisely determined. The region where the electron can probably be found is known as the electron cloud.
What is By stable?
Bistable = stable in two states
Why does the lithium atom want to lose an electron?
It is an alkali metal (Group 1 element). So, it needs to lose one electron in order to form a full valence shell (the one beneath it). Full valence shells are more stable states.
What is the result of sodium atom transferring an electron to a chlorine atom and they become stable?
The result is what you use to put in the food. Table salt (or sodium chlorine). It's a very stable compound, as each of the ions have their orbitals completely filled. Recall that in their normal states, Sodium has only one valence electron, and the Clorine is missing one to have its orbitals filled.
Hydrogen gas exist at as h2 rather than h why this so?
Elemental Hydrogen is a diatomic element. At STP (standard temperature and pressure) the stable form of the element is for two atoms to be bonded together. In Hydrogen's case, each atom of Hydrogen brings one electron. These two electrons are shared, forming a covalent bond. This sharing of each of the atom's electrons is a more stable state than that of having only a single electron. Stable states are thermodynamically preferable. Electrons travel around atoms in orbitals. Each orbital has two electrons. For Hydrogen, having the 1s orbital filled with it's original electron and the electron shared from the other atom is more stable. In atoms above Helium, the octet rule prevails.
