A chemical compound always consists of two or more elements combined together, and therefore molecules of at least two atoms. A substance which was only one element would simply be a sample of the element. There are some monoatomic
elements, the noble gases, helium and group 18 neon argon etc.

Which polyatomic ion forms a neutral compound when combined with a group 1a monatomic ion in a 1 2 ratio?
The sulfate ion (SO4^2-) forms a neutral compound when combined with a group 1a monatomic ion in a 1:2 ratio. This means that for every one monatomic ion from group 1a, two sulfate ions are needed to form a neutral compound.
Which polyatomic ion forms a neutral compound when combined with a group 17 monatomic ion in a 11 ratio?
Ammonium, NH4+
Which poly-atomic ion forms a neutral compound when combined with a group IA monotonic ion in a 11 ratio?
The polyatomic ion that forms a neutral compound when combined with a Group IA monatomic ion in a 1:1 ratio is the nitrate ion (NO₃⁻). When the nitrate ion pairs with a Group IA cation, such as sodium (Na⁺), they create a neutral compound like sodium nitrate (NaNO₃). This 1:1 ratio ensures that the positive charge of the monatomic ion balances the negative charge of the polyatomic ion.
Which elements are naturally monatomic?
These are the elements that are NATURALLY monatomic: Helium Neon Argon Krypton Xenon Radon
Which noble gas is monatiomic?
All noble gases are monatomic and exist as individual atoms.
Why is monatomic nonsense?
Because it has to have more than one atom to be a compound.
Is borax monatomic?
No, borax is not monatomic. It is a compound made up of boron, oxygen, and sodium ions.
Is sulfur hexafluoride a monatomic ion?
Sulfur hexafluoride is not a monatomic ion but in fact a molecular compound.
Which polyatomic ion forms a neutral compound when combined with a group 1a monatomic ion in a 1 2 ratio?
The sulfate ion (SO4^2-) forms a neutral compound when combined with a group 1a monatomic ion in a 1:2 ratio. This means that for every one monatomic ion from group 1a, two sulfate ions are needed to form a neutral compound.
Is hellium a compound?
No, helium is not a compound. It is a monatomic gas, meaning it consists of single atoms of helium.
Is potassium iodide a poly atomic ion?
No, potassium iodide is a compound composed of the monatomic ion K+ (potassium cation) and the monatomic ion I- (iodide anion). It is not a polyatomic ion.
Which polyatomic ion forms a neutral compound when combined with a group 1A monatomic ion in a 1 to 2 ratio?
The sulfate ion (SO4^2-) forms a neutral compound when combined with a group 1A monatomic ion such as potassium (K+) in a 1:2 ratio. This results in the formation of K2SO4, which is a neutral compound.
Is sulfur hexafluoride an example of a monatomic ion?
No, sulfur hexafluoride is not an example of a monatomic ion. Sulfur hexafluoride is a compound consisting of one sulfur atom and six fluorine atoms bonded together. Monatomic ions are single atoms that have gained or lost electrons to become charged ions.
Which polyatomic ion forms a neutral compound when combined with a group 17 monatomic ion in a 11 ratio?
Ammonium, NH4+
What formula for a compound has monatomic and polyatomic ions present?
The answers have to be include monatomic and plyatomic ions present and ratio between positive and negative ions is one to two, and a group IIA element that loses one half of its total electrons upon ion formation is present, and the sum of the atomic numbers for the two elements involved in the polyatomic ion is 13.
What does monatomic mean?
'Monatomic' means having or consisting of single atoms.
Which polyatomic ion forms a neutrak compound when combined with a group 1A monatomic ion in a 1 1 ratio?
Since Group 1A monatomic ions have a charge of 1+, only a polyatomic ion with a charge of 1- can combine to form a compound in which the monatomic ions and polyatomic ions are present in a 1 to 1 ratio. The following polyatomic ions with a charge of 1- can form a neutral compound when combined with a group of 1A monatomic ion in a 1 to 1 ratio.acetate - C2H3O2-bicarbonate (or hydrogen carbonate) - HCO3-bisulfate (or hydrogen sulfate) - HSO4-chlorate - ClO3-chlorite - ClO2-cyanate - OCN-cyanide - CN-dihydrogen phosphate - H2PO4-hydroxide - OH-nitrate - NO3-nitrite - NO2-perchlorate - ClO4-permanganate - MnO4-thiocyanate - SCN- Source: http://chemistry.about.com/od/chartstables/tp/common-polyatomic-ions.htm
