Which of the following is a negative ion?
Na+1,Na,O-2,O? All of them?
Ah, negative ions. They're like the pessimists of the ion world. Let's break it down.
Na+1 is a positive ion. It's like that super smiley person who's always positive about everything.
Na, however, is just plain old neutral sodium. It's like a regular person on a regular day, not particularly positive or negative.
O-2 is a negative ion. It's like the grumpy friend who always finds something to complain about.
O, on the other hand, is also a neutral atom, just like sodium. It's like that friend who's just chill and goes with the flow.
So, to answer your question, the negative ion amongst the options is O-2. It's the one that can suck the positivity out of any situation.
Of the options given, the negative ion is O-2. Na+1 and Na are positive ions, while O-2 is a negative ion.
To determine which of the given ions is a negative ion, we need to understand the concept of ions and their charges.
An ion is an atom or a group of atoms that has a net electric charge. Ions are formed when atoms gain or lose electrons. Positively charged ions are called cations, while negatively charged ions are called anions.
In the given options, we have Na+1, Na, O-2, and O. The "+1" and "-2" in the notation represent the charge of the ion.
Na+1 is a positively charged ion, also known as a cation. It has lost one electron, resulting in a net positive charge of +1.
Na is the neutral form of the element sodium. It has neither gained nor lost any electrons and has no net charge. Therefore, it is not an ion.
O-2 is a negatively charged ion, also known as an anion. It has gained two electrons, resulting in a net negative charge of -2.
O is the neutral form of the element oxygen. It has neither gained nor lost any electrons and has no net charge. Therefore, it is not an ion.
So, out of the given options, the negative ion is O-2.
