What else can I help you with?
Would you expect the second electron gain enthalpy of O as positive more negative or less negative than the first Justify your answer?
The second electron gain of an oxygen atom would be expected to be less negative. The reason for this outcome is that the oxygen atom gaining a second electron already has one electron and thus a negative charge. This negative charge repels the second electron to some extent, making the enthalpy of this process less negative than when the first electron was added to the neutral oxygen atom.
Does 02 have a negative charge?
No, O2 (molecular oxygen) does not have a negative charge; it is a neutral molecule. Each oxygen atom shares electrons in a covalent bond, resulting in a balanced distribution of charge. However, individual oxygen atoms can gain or lose electrons to form charged species called ions, such as O2- (oxide ion), which does have a negative charge.
What is the most nonmetallic element in group 16 A sulfur B selenium C tellurium D oxygen?
D. Oxygen. Oxygen is the most nonmetallic element in group 16, also known as the chalcogens. It has a high electronegativity and tends to gain electrons to form negative ions.
Do oxygen gain or lose electrons?
Oxygen is an oxidizer, it will gain electrons in a reaction to complete it's valence shell.
Which type of elements make negative ions?
Elements on the right-hand side of the periodic table, that is to say, non-metals, will form negative ions. This is because, in order to become stable, they need to GAIN electrons, making them more negative than they were before. For example, Oxygen has 6 valence electrons, and needs 2 more to reach a stable octet. If it gains 2 electrons is will have a charge of -2, making it a negative ion.
Why oxygen has negative charge?
Oxygen does not have a negative charge on its own. Oxygen is a neutral element with 8 protons and 8 electrons. However, in certain chemical reactions, oxygen can gain or share electrons with other elements, resulting in the formation of ions that may have a negative charge.

The names of negative ions that form when atoms gain electrons have the ending .?
-ide, as in: chlorine -> chloride fluorine -> fluoride oxygen -> oxide etc.
Is oxygen's charge positive or negative?
Oxygen typically has a charge of -2.
Is oxygen a negative charge?
As an element oxygen is neutral, but it forms negative ions.

D. Oxygen. Oxygen is the most nonmetallic element in group 16, also known as the chalcogens. It has a high electronegativity and tends to gain electrons to form negative ions.
What electric charge is the characteristic for an ion of 0?
O that is oxygen is a non metal and a non metal has a characteristic of gaining electrons so when they gain electrons the also gain a net charge in negative as no. of protons become less than the no. of electrons. now oxygen has atomic no. 8 and valency of 2 so it requires 2 electrons to complete an octet i.e. 8 electrons in the outermost shell and to get a negative charge. since it will gain 2 electrons so it will have a net charge -2. The oxidation number of oxygen is -2, except in a few cases, including superoxides (-1/2), peroxides (-1), and oxygen fluorides (+1, +2).
When you subtract a negative from a positive is that a gain or loss?
When you subtract a negative number from a positive number, it is equivalent to adding the two numbers together. Therefore, it is a gain.
What is the charge on an oxygen atom?
Corrected: All atoms have a neutral charge until they lose or gain electrons. Once they lose/gain electrons then they are considered ions with respectively positive (on loosing) or negative charge (on gaining electrons, as oxygen tends to do).NO: 2-. It's the same as minus 2, but is written as 2- for conventions.
Why oxygen forms positive charge with fluorine?
Oxygen does not typically form a positive charge with fluorine. Oxygen tends to gain electrons to achieve a stable electronic configuration, while fluorine tends to gain electrons to reach a stable octet. This results in the formation of a covalent bond between the two elements, with oxygen typically having a partial negative charge and fluorine having a partial positive charge.
How many electrons must the oxygen atom lose to be stable?
Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.
