What charge do the VIIIA noble gases have?
The VIIIA noble gases have a charge of zero since they have a full outer electron shell, making them stable and unreactive.
What charge do selenium have?
Selenium typically exhibits a charge of -2 when it forms compounds, as it often gains two electrons to achieve a stable electron configuration similar to that of noble gases. In its elemental form, selenium is neutral, but in compounds like selenides, it carries this negative charge. Additionally, selenium can have positive oxidation states, such as +4 and +6, in certain compounds, but these are less common.
What is a stable element with a zero charge?
A stable element with a zero charge is one that has an equal number of protons and electrons, resulting in no net electric charge. For example, a neutral atom of carbon, which has six protons and six electrons, is a stable element with a zero charge. Other examples include oxygen, nitrogen, and noble gases like neon or argon, all of which maintain stability with balanced positive and negative charges.
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.
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.
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.
What charge do the VIIIA noble gases have?
The VIIIA noble gases have a charge of zero since they have a full outer electron shell, making them stable and unreactive.
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.
Why the electrical charge in an atom is zero or neutral?
There is a neutral charge on an atom when the number of protons is equal to the number of electrons. This is most common in the Noble gases, such as Neon (atomic number 10, the second Noble Gas), where there are 10 protons and 10 electrons, with the negative charge on the electrons balancing out the positive charge of the protons exactly.
What are the oxidation states of group 18 elements?
0, neither positive or negative. They are the noble gases, and as such, very unreactive
What is helium's charge?
helium`s charge is H+, is a positive charge
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 a stable element with a zero charge?
A stable element with a zero charge is one that has an equal number of protons and electrons, resulting in no net electric charge. For example, a neutral atom of carbon, which has six protons and six electrons, is a stable element with a zero charge. Other examples include oxygen, nitrogen, and noble gases like neon or argon, all of which maintain stability with balanced positive and negative charges.
Do elements have bonds?
Elements can form bonds with each other to create compounds, where atoms are held together by chemical forces. In their pure form, elements can exist as atoms existing without any chemical bonding, such as in the case of noble gases.
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.
Do metals form positive ions?
No, metals do not form negative ions: Only non-metals form negative ions - this ability (to gain electrons) is intrinsic to the nature of non-metals. Only metals form positive ions - this ability (to lose electrons) is intrinsic to the nature of metals. A positive ion (cation) is formed by removing electron(s) from an atom or group of atoms. A negative ion (anion) is formed by gaining electron(s) an atom or group of atoms.
