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 else can I help you with?
Do non metals Only forms positive ions?
Selective metals form positive ions. Some though do not. Those are called Nobel Gases. These are in groups 13-18.
Nobel gases are also known as the?
Inert gases
Are Nobel Gases very active?
No,they are not active.They are inert gases.
Summarize the properties of nobel gases?
Noble gases are colorless, odorless, and tasteless gases that are nonreactive due to their stable electron configuration. They are located in group 18 of the periodic table and have complete outer electron shells. These gases have low melting and boiling points, making them useful in applications where inert atmospheres are needed.
Which gas is nonatomic at room temperature and pressure?
Except Nobel gases all other gases are molecular. The Nobel Gases, Family or Group 18 are atomic.
Nobel gas can also be called?
Nobel gases are also called inert gases because of their reluctance to combine with other substances.
Why are noble gases very reactive?
Nobel gases are very unreactive.
What is the explanation for sonoluminescence?
In case of sonoluminescence, you have ultrasonic sound sent to the air bubble in liquid. As liquid is very good conductor of sound, it goes to air bubble easily. Then the sound encounters the air in the bubble. Air is not good conductor of sound as compared to liquid. So the high energy ultrasound gives energy to the air molecules. Which gets ionized and get converted into oxides or ionized. The remaining 1 % of the Nobel gases can not be oxidized. As they have complete octet in there last orbit. So high energy is delivered to Nobel gases. You can have better effect of sonoluminescence in artificial bubbles with Nobel gas. They loose electron from there outer orbit. The ionized atoms repel each other due to positive charge. So the size of the bubble increases. (As Nobel gases have highest energy of ionization, they can emit highest energy.) Then as energy is released in 'quanta' in the form of light. (Here energy is released in the form of electromagnetic waves. But you can 'see' light only.) As energy is released from the atoms of Nobel gases, electrons re-enter there outer orbit. As a result of this re-entry of electrons, positive charge on the atoms of Nobel gases disappears. They no longer repel each other and the bubble shrinks back. This process can be repeated any number of times. This is purely physical phenomena, probably explained.
Why don't nobel gases form chemical bonds?
noble gases are already stable.
Is Nobel gases metals or non metals or metalloids?
Non-metals, they are all gases.
What property do all the Nobel Gases share?
the noble gases have their valence shell complete
Why do noble gases rarely form bond with other atom?
the nobel gases are already stable, with full octets of valence electrons
