It depends on what level or period the atom is. Consult the Periodic Table, and you will see that period 1 has two electrons, periods 2 and 3 have 8, periods 4 and 5 have 18, and 6 and 7 have 32. Please see the related link below for more information.

How does a vacuum tube work?
contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—from the cathode to the anode. Adding one or more control grids within the tube allows the current between the cathode and anode to be controlled by the voltage on the grids.[5]
Why induced emf alternates?
Here is A Simple answer for this question as you know that emf is induced in the conductor when there is change of flux linkage to the conductor which gives rise to the inducement of electric field in the conductor that provide drift velocity to the electrons hence emf is induced in the conductor but the last only till the change in flux in progress and becomes zero as soon as the flux linkages becomes constant hence we summaraize that for inducement of current there must be change in change of flux hence change in electric field that gives rise to allternating emf.
How long can power generators provide power?
It depends on the size and power that the generator provides; some are only good for a couple of hours, some last for twenty four hours and still others are designed to last for up to four days.

What the difference between 10-2 wire and 10-3?
The first number indicates the size of the wires, in this case #10 AWG (American Wire Gauge). The last number refers to the quantity of conductors, excluding the ground wire, if any. 10-2 wire would have two conductors, typically a black used for the hot, and a white used for the neutral. If the label says "10-2 with ground" then the cable would also contain a bare or green insulated ground wire. 10-3 wire contains all the above plus one more wire, typically red, used for an additional hot.
How many electrons are in the last orbit of Chlorine?
In the last orbit of Chlorine includes 7 electrons.Name: Chlorine Symbol: ClAtomic Number: 17Atomic Mass: 35.4527 amuNumber of Protons/Electrons: 17Number of Neutrons: 18
Would a atom prefer to lose or gain electrons?
for that you should have the knowledge of the electron configuration 2,8,8,18,32,.. meaning first electronic orbit can have at the most two electrons. second orbit can have only 8 electrons and so on.... Now, for example calcium atomic number is 20 . so how will be the electrons placed 2 will go in the first orbit, 8 will go in the second orbit - so till now total is 10 we still have 10 more electrons to arrange. 8 electrons go in the third orbit and last 2 electrons go in the fourth orbit which actually has the capacity to accept total of 18 - now 2 electrons come in the fourth orbit so 18-2=16 . for any element it requires a lot of energy to get 16 electrons from the atom of other element so it will be better to loose 2 electrons for the calcium atom. Ca +2 means it has 2 electrons to loose . try this with different element and if you have any problem I will help you
What does the electron configuration of an atom reveal?
It can reveal the number of valence electrons in the last shell.
What determines the stability or reactivity of an atom?
The numbers of protons and neutrons in its nucleus, and the number of electrons in its valence shell. The number of protons and neutrons will affect the element and the isotope number, some isotopes are stable, some are not. Atoms are also more stable with a full outer energy level (octet rule - 8 electrons in the outermost shell).
What do metals do with electrons?
Metals are elements belonging to first , second or third group. They have one ,two or three valence electrons (electrons present in the last orbit of an atom). They lose this electrons to gain stability as they are highly unstable and by doing so they react . NOTICE: An atom can only lose the electron if an atom of other element is ready to take it.
What are Lewis electrons?
valence electrons or electrons of the last level of electrons in an atom or the electrons in the last energy level of an atom, they have a negative chargethese electrons usually are the ones that take part in reacting, such as ionic bonding and covalent bonding :)
How many electrons are in the last electron cloud around a Nickel atom?
There is two electrons in the last ring of the Nickel atom. Go and check the related link for a picture.
Valence electrons are the electrons found on the last shell of an atom true or fase?
True
What is valency of chloride?
single valency. last orbit has 7 electrons.
Why does magnesium and oxygen form an ionic bond?
Oxygen have 6 electrons on the outer sell so it need 2 more electrons to gain full outer shell. Magnesium have 2 electrons on the outer sell so It have to lose 2 electrons to gain full outer sell. They combine easily by a strong ionic bond. Its formula is MgO, it has no overall charge.
What tells you how many electrons an atom must gain lose or share to become stable.?
atomic mas
In general an atom is more stable with a full last electron shell What is the measure of the attraction that an atom has for additional electrons?
electron affinity C. electrons
