Where are electrons located in an element?

well, first you have to understand that elements are made up of atoms. atoms contain protons, neutrons and electrons. the number of protons is equal to the number of electrons. the protons and neutrons are located in the mucleus, while the electrons are located in the outer rings of the atoms. the first ring can hold a maximum of 2 electrons and the second and third can hold a maximum of 8 each up to element number 20. They are usually drawn in pairs. For example, look at this potassium atom. The electrons are on the outer shells.


What does it mean if an element has 8 electrons?

it has a full octet


What holds electrons in their shells?

The electrons "orbit" the nucleus of an atom. They do so because they are attracted to the positive charge of the protons inside the nucleus. They do not usually leave the atom because of this attraction, and do not usually fall into the nucleus because they are moving.


Each electron shell in an atom contains?

they contain electrons, which are negatively charged and revolve at high speed around the nucleus of an atom. the first shell (the one nearest to the nucleus) can hold a maximum of 2 electrons. the second shell can hold a maximun of 8 electrons. If there any remaining electrons they will go on the third shell. the third shell can hold a maximum of 18 electrons. the shells closest to the nucleus (inner shells) must contain their maximum number of electrons before attempting to fill the energy levels to a higher energy.


How many electrons can an atoms 4th energy level hold?

32 electrons maximum

Why is chlorine in period 3?

Chlorine is in period three because that is how many outer shells it has. One period is one shell... In the First outer shell you can only hold.. 2 electrons. Second outer shell can hold 10 electrons. Third outer shell can hold 18 electron. Protons + Electrons = Atomic Number Atomic Number - Atomic Mass = Number of Neutrons in Outer Shells


How do atoms benefit from double or triple bonds?

all atoms what to get a complete outer energy ring of electrons. al that is except for the noble gases they all ready have a complete outer electron cloud. what atoms do is either share or take away an electron depending on its needs. for example lithium is alkaline earth metal in group 2 there for it needs to lose 2 electrons to have a complete outer ring. the rings are like shells. the first can only hold 2 electrons at a time the second can hold 8.noble gases have a complete outer ring

What Rule states that the first ring on an atom can hold 2 electrons and all others can hold 8?

Well I tink you mean the duet rule appling to first period and octet rule. The octet rule relates to the stable configuration that atoms can achive by sharing electrons, and is the outer shell of the noble gases. HOWEVER for period 3 and above atoms can hold more than 8 electrons in their outermost shells.

How many electrons are in its outermost shell?

It depends on the element in question. The outer most shell of electrons will hold the remainder of the electrons after all inward shells are filled. The first shell will only hold up to 2 electrons. After each shell holds up to 8 electrons (if the atomic number is <20).


What atom can hold 18 electrons in its outer level?

No atom can hold 18 electrons in its outer energy shell - there is the valence rule, stating that the maximum for the outer shell is 8 electrons.


How many electrons can the second level hold?

The n = 2 level of hydrogen can hold eight total electrons--6 in the p shells and 2 in the s shells.


How can i convert real number to round that number?

An electron shell may be thought of as an orbit followed by electrons around an atom's nucleus. The closest shell to the nucleus is called the "1 shell" (also called "K shell"), followed by the "2 shell" (or "L shell"), then the "3 shell" (or "M shell"), and so on further and further from the nucleus. The shell letters K, L, M, ... are alphabetical.Each shell can contain only a fixed number of electrons: The 1 shell can hold up to two electrons, the 2 shell can hold up to eight electrons, and in general, the n shell can hold up to 2n2 electrons. Since electrons are electrically attracted to the nucleus, an atom's electrons will generally occupy outer shells only if the more inner shells have already been completely filled by other electrons. However, this is not a strict requirement: Atoms may have two or even three outer shells that are only partly filled with electrons. (See Madelung rule for more details.) For an explanation of why electrons exist in these shells see electron configuration.[1]


How many electron fill an orbital?

Eight. The electrons with the highest energy levels are counted as the valence, or outer, orbitals. There are shells that contain more electrons such as D or F shells that can accommodate for 10 and 14 electrons respectively, however they are a lower energy level than their respective S and P shells that fill up before them which hold 2 and 6 electrons equaling a max of 8 outer orbitals.


How many of atoms are in the 3rd shell of an atom with 4 shells?

If you are asking about the number of electrons then it would be 8. The first shell can hold a maximum number of 2 electrons. The second and third shell would have a maximum of 8 electrons each.
