1 atom of the element, carbon, would have 4 electrons in its outer most shell. It's electron configuration is 1s2 2s2 2px1 2py1.
2 is the outer most shell, so there are 4 electrons in shell 2.

Why does chlorine have such a strong attraction for electrons?
Because it has 7 electrons in its outermost (valency) shell and getting 8 electrons there would close the shell.
How many electrons would be present in the valence shell of a iron atom?
Valence electrons are the total amount of electrons on the outermost shell of an atom. Meaning if the last shell has two, the valence electrons are two. But a complete valence shell would hold eight.
What element that would show chemical properties most similar to carbon?
Silicon Directly below it on the periodic table
How many electrons are there in the valence shell of a nitrogen atom?
Nitrogen has 5 valence electrons. Its atomic number is 7 therefore it has a total of 7 electrons. If you put this in a Bohr-Rutherford Diagram, there would be 2 electrons in the first shell (Helium structure) and 5 electrons in the outer shell. The number of electrons in an element's outermost shell is its number of valence electrons.
Why is the ionisation energy of fluorine higher than iodine?
The best modern answer would involve quantum chemistry, but an easier to understand explanation is that the outermost electrons in fluorine are much closer to the nucleus that provides the attraction to hold the electrons and nucleus together as an atom than are the outermost electrons in iodine. This is sometimes called the "screening effect" of inner shell electrons that weakens the attraction between the nucleus and the outer shell electrons in large atoms such as iodine.
What happens if the outermost electron shell is empty?
the shell would never be empty, there would be another shell under it and it would have all of its valence electrons

Valence electrons are the total amount of electrons on the outermost shell of an atom. Meaning if the last shell has two, the valence electrons are two. But a complete valence shell would hold eight.
How many electrons are in the outter shell of magnessium?
There are 12 electrons in the electron shell of magnesium, the same number as protons. As for the outermost shell, it would be 3s2, meaning there are two electrons in the third "s" shell.
Where would you find valence electrons?
They are the electrons in the outermost shell, and are the ones involved in most chemical reactions.
What element that would show chemical properties most similar to carbon?
Silicon Directly below it on the periodic table
How many electrons would be needed to fill its outer shell for carbon?
4 to fill the 2p shell
What are group of atoms that gains or loses electrons?
To become stable. In other words, they gain ( or sometimes lose) electron to acheive a stable octet. In most cases, this would mean that the atoms are trying to have 8 electrons in their valence (outermost) shell of electrons. In other cases, ( helium and hydrogen) they just need 2 electrons in their outer electron shell. Methane for example. (formula CH4) ... Carbon has four electrons in its outermost shell ( it has two in the inner shell ... 6 total). It has four electrons so hence it is in group 4 of the periodic table. So carbon wants 8 electrons in its valence shell, that means that it has four more to go. Hydrogen has 1 electron in its outer shell and only needs one more. So, the carbon and the 4 hydrogens bond covalently. The carbon shares one electron from each of the four hydrogens ( 4 [ from itself] and 4 [ one from each hydrogen] = 8). So the carbon is satisfied. On the other hand, each hydrogen would share one of carbon's electrons to attain 2 each in their outer shell. So hydrogen is stable with its two electrons and carbon is stable with its 8. They gain electrons to become more stable. p.s. Google covalent and ionic bonding.
If the atom which has a 2 valence electrons became a positive two cation how many electrons would it then possess?
It would be a group 6 element posessing 8 electrons in the outermost shell but the total number would depend on which element it was.
How many electrons would be expected in the outermost electron shell of an atom with atomic number12?
The element is magnesium with the electronic configuration 2, 8, 2 and has 2 valence electrons.
Which bond forms by sharing electrons in the outermost shell?
The sharing of electrons between atoms forms a covalent bond. If electrons are donated from one atom to another to form a bond this would be an ionic bond.
How many electrons are there in the valence shell of a nitrogen atom?
Nitrogen has 5 valence electrons. Its atomic number is 7 therefore it has a total of 7 electrons. If you put this in a Bohr-Rutherford Diagram, there would be 2 electrons in the first shell (Helium structure) and 5 electrons in the outer shell. The number of electrons in an element's outermost shell is its number of valence electrons.
