What will you get when you add atoms together?
When atoms combine at the level of the electron shell, you get molecules. If the combination occurs at the nuclear level, you get nuclear fusion and the release of lots of energy.
Why alkali metals do not show 2 oxidation state?
Because they have only one electron in their valency shell. The second oxidation state would require the atom to lose an electron from its penultimate shell which is full.
Is The shell model a physical model?
Yes, the shell model is a physical model used in nuclear physics to describe the structure of atomic nuclei. It is based on the idea that nucleons (protons and neutrons) occupy energy levels or "shells" within the nucleus, similar to the electron shells in an atom. The shell model helps explain certain nuclear properties and phenomena.
What is the lithium main electron level?
The electron valence shell has 1 electron.
How many electrons shells does a helium atom have?
The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.
What is the effective nuclear charge for an electron in the outermost shell of a fluorine atom F?
The effective nuclear charge for an electron in the outermost shell of a fluorine atom (F) is approximately +7. This charge results from the balancing of the positive charge of the nucleus with the shielding effect of inner electrons.
What is the overall of an atom?
The overall of an atom is a nucleus (protons and neutrons), and 1 or 2 electrons. The rest are for large atoms: an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons.
What is the relationship between the electron configuration of neon and the effective nuclear charge of Ne?
The electron configuration of neon determines its effective nuclear charge. Neon has a full outer electron shell, which means it has a high effective nuclear charge because the positive charge of the nucleus is not shielded by inner electrons.

When atoms combine at the level of the electron shell, you get molecules. If the combination occurs at the nuclear level, you get nuclear fusion and the release of lots of energy.

During a nuclear reaction what happens to the outer electrons?
In the case of a nuclear explosion they virtually disappear. The heat created in the immediate vicinity of the fission or fusion (fission-fusion) event is so intense (the energy is so great or the temperature is so high) that no atom can hang onto its electrons. The electrons are all "blown away" in the blast. As the blast expands and the energy "thins out" during the few minutes after the blast, the atoms will all recapture electrons through static means. In the case of nuclear fission in a nuclear reactor, the nucleus of either U235 or Pu239 splits up into two nuclei called the fission fragments. The total number of protons in these two nuclei is the same as in the parent nucleus, so they will require the same total number of electrons to form neutral atoms. The arrangement of the electron shells will be appropriate to the new elements formed. As there is a range of possible combinations of fission fragments there is no one answer, the shell arrangement for each element is different.
Why does not the nucleus attract the atoms from top to bottom in a periodic table?
Down a group, the number of shell increases and the electron enters into a different shell. Hence, the distance between the nucleus and valence electron increases and the nuclear attraction decreases
How many electrons does sulfur have in its third electron shell?
Sulfur has six electrons in its third electron shell.
Does lithium have a full outer shell?
no it only has 1 electron in the outer shell
Are valence electrons located in the electron cloud?
The outermost shell of an electron is called the valence shell. This shell may or may not have electrons.The valence shell is a part of the electron cloud.So your answer isYes, the valence electrons are located in the electron cloud.
When an alkali metal reacted with a non metal what happens to the loan outer shell electron?
The electron outside the shell donate its electron to the one inside the shell
If an element is chemically active what is the state of its outer electron shell?
The key to "happiness" for an atom is a full outer electron shell. (The outer electron shell is called the valence shell.) There are two conditions that cause a shell not to be full. Either it has only an electron or two (or three) in the outer electron shell or it's short an electron or two in that outer shell. The direct answer to the question is that if an element is chemically active, its outer electron shell is incomplete or is not full.
