None of them have a negative charge. Or a positive charge. They can be ionized by high voltages, as (for example) neon is in a neon sign. However, neon doesn't have a monopoly on that, all of them exhibit the same behavior.

What charge do the VIIIA noble gases have?
negative charge with gain of electrons
Do all atoms have a positive and negative charge?
Yes and no. the nucleus has protons and neutrons so it has a neutral charge and a positive charge.Further answerBut in total the resultant charge is positive, which is what the questioner wants to know.Yes the nucleus of an atom carries a positive charge.
Why does atoms of noble gases do not easily form?
Elements form compounds to seek electrical equillibrium. Ions are basically either positive or negative, and free ions of elements seek to bond with other elements to form a neutral charge. Example: Na+1 is looking for a -1 ion, such as Cl -1, so that it can reduce its charge to zero. Noble gases have what is known as an "octet" which is very stable electron configuration. Because of this, a noble gas does not seek to bond with another element to either give up or gain a charge.
In the direction of current?
Current flows from positive to negative.Electrons flow from negative to positive.This is historic, and arbitrary.Another AnswerThe original answer is not wholly correct, and neither is it correct to say that the direction of an electric current is 'arbitrary'. Current direction is defined in terms of its direction through a load (never through the voltage source, such as a battery or generator).An electric current is a flow of charged particles. In metal conductors, these arenegatively-charged electrons. Therefore, in metal conductors, current flows from negative to positive through a load. This is because the negative electrons in a conductor are repelled by an external negative charge and attracted towards an external positive (or 'less negative') charge.In the 18th century, long before the nature of the atom was understood, scientists, such as Benjamin Franklin believed that an electric current was the flow of some mysterious 'fluid' that moved from a higher pressure to a lower pressure. Naturally, the considered the higher pressure to be 'positive' and the lower pressure to be 'negative'. Therefore, they believed current flowed from 'positive to negative'. Faraday agreed with this direction, based on his observations of his experiments in electrolysis (although he thought that current was a 'field' rather than a 'fluid'). Unfortunately, they were wrong.To distinguish the latter from the former, a direction of positive to negative is termed 'conventional flow', whereas a direction of negative to positive is termed 'electron flow'. Modern textbooks use either 'conventional flow' or 'electron flow', depending on the author's preference.
Why does a magnesium atom have no charge?
Easiest to understand while looking at a periodic table. As you know, all gases react to try to become nobles. Magnesium has 12 electrons, and the closest noble gas (neon), which Mg wants to become, has 10 electrons. So in order to be balanced, Mg has to lose 3 electrons (you may initially think it needs to lost 2, but include Mg when you are counting back --> 12,11,10) . When an atom loses electrons, which have a negative charge, it will become positive, as it will have more positive H+ atoms than negative e- atoms. Again, if you look at your periodic table, this is quite simple to figure out :)
What charge do the VIIIA noble gases have?
negative charge with gain of electrons
What is different between atom and ion?
An ion is an atom that has either gained or lost electrons. An ion has either a positive or negative charge, depending on whether it gained electrons (negative) or lost electrons (positive), while an atom is electrically neutral. When not part of a molecule, elements usually exist in an ionic form, the exception being the noble gases, or the elements on the leftmost column of the periodic table.
Does nobel gases have a negative or positive charge?
Neither. No element has any charge, on it's own. You may often see H+ and Cl- but this is misleading (especially Cl-).I won't go into that. But noble gases do not have a charge. Also...they probably never will have a charge. They rarely ever react and are extremely stable.Although they ARE very electronegative...this is not at all the same as being negative and, in fact, acquiring another electron is highly unfavourable for them.
State of a material depends on?
If you are talking about solids liquids and gasses, then it depends on how fast the molecules are moving. in solids, they vibrate in place. In liquids they slide past one another. In gases the bounce. In plasma the bounce with either a positive or negative charge.
Do elements have bonds?
No, an element has no charge. However, elements can lose or gain electrons to become a charged ion.
What charge are metal ions?
Group 1A: +1 charge because it lost an electron (more protons than electrons). 2A: +2 " " " " 2 electrons. 3A: +3 " " " " 3 " 4A: Can lose or gain 4 electrons depending on the element. 5A: -3 charge becuase it gained 3 electrons. 6A: -2 charge " " " 2 " . 7A: -1 charge " " " 1 " . Be careful about Transition Metals. They can have various charges. Ex. ( Fe = Iron can have a +2 or even a +3 charge. Au = Gold, can have a + (equals 1) or +3 charge. 8A are the noble gases.
What are the oxidation states of group 18 elements?
0, neither positive or negative. They are the noble gases, and as such, very unreactive
Is forced draft has negative pressure drop?
No, the forced draft fan has positive pressure as it just forces yhe air into the combustion chamber.only the induced draft fan has negative pressureas it removes the flue gases & exhaust gases is stacked up
What is ionic charge of oxygen?
O2- The ionic charge of something can be determined by it's place in the Periodic Table. Elements in groups 1-3 have a positive charge the same as their group number, e.g. Magnesium (Mg) Is in group 2 so its charge is Mg2+ Elements in groups 5-7 have a negative charge equal to their group number -8 e.g. Oxygen is in group 6 (6-8=-2) So its charge is O2- The noble gases (Group 0) do not have an ionic charge.
When electric current pass through water.Which gases r obtained as anode and which obtain as cathode?
Oxygen at positive anode and Hydrogen at negative cathode

What is the charge of two ions of fluorine F2?
Ions such as fluorine always have a Negative charge- when looking at the periodic table you will see groups 8,7,6,5,4 and 3 on the right side. All noble gases in Group 8 have no charge, but going to the left: 7 = -1 charge 6 = -2 charge 5 = -3 charge 4 = -4 charge This only works for nonmetals, not transition metals so be careful. So, looking at Fluorine it is in Group 7 7 Nonmetals always have a -1 charge. 2 Fluorine Ions * -1 = -2 -2 is your answer. When it meets with a positive ion (Groups 1 and 2 on the left side of the periodic table), the two charges will need to balance. So the positive ion will need to be +2. This can happen naturally (positive ions in Group 2 are +2, so 2F and 1Ca will work) or because there are enough positive ions to balance the charge (positive ions in Group 1 are +1, so having 2F and 2Na will work). Good luck :)
