Think about the question and each of the answers, particularly d) Polyatomic atoms.
Even if I had no knowledge of chemistry, (d) would be the obvious answer.
The question wants ions with MORE THAN ONE ATOM. Poly=Many/multiple, so 'polyatomic' quite literally means 'more than one atom'.
negative questions positive questions
Some examples of formal commands include positive and negative commands. For example, telling a dog to bring you your paper by saying "Fifi, bring me my paper! is a positive command, whereas telling your dog not to bring you your paper by saying "Fifi, don't bring me the paper, is a negative command.
Gram Negative
In a weighed graph, a negative cycle is a cycle whose sum of edge weights is negative
Yes as they are negative you can conclude, the test is negative and nothing to worry.
False. Polyatomic ions can carry either charge. For example, consider the sulphate ion - SO42- or the hydroxide ion, OH-. Negative polyatomic ions are, in fact, generally more common than positive ones.
b.
Phosphate (PO43-) is a polyatomic anion. The way to tell this is to look at the charge - an anion has a negative charge and a cation has a positive charge.
A polyatomic anion is a tightly bound group of atoms that behaves as a unit and has a negative charge.A monatomic anion consists of a single atom with a negative charge.
polyatomic ions are those ions which carry more than one atom,we can say that a group of atoms having single charge( which may be positive or negative) are polyatomic ions.
No. Not only is it not true, but it it were, there would be no polyatomic ions!
Most polyatomic ions have a negative charge. There are only 2 positive polyatomic ions; Mercury(I) ion and Ammonium ion. False.
Sodium Hydroxide. the OH in NaOH is a polyatomic ion and has a negative charge.
a tightly bound group of atoms that behaves as a unit and has a positive or negative charge
Ions are charged by definition: they are atoms or molecules that have either lost or got one or more electrons so to have a positive or negative charge. Examples are Trifluoromethan ion CF3- Trifluoroacetic acid ion CF3COO- Nitrogen ion NH2-
examples of negative duties
An ion that is made up of more than one atom.
