What three hydrogen-containing polyatomic anions are essential components of living system?
The three hydrogen-containing polyatomic anions essential for living systems are phosphate (PO4^3-), bicarbonate (HCO3^-), and hydroxide (OH^-). These ions play important roles in biological processes such as energy transfer (phosphate), pH regulation (bicarbonate), and chemical reactions (hydroxide).

Do polyatomic anions always end in -ide?
No, polyatomic anions do not always end in -ide. Some polyatomic anions end in -ate or -ite, depending on the number of oxygen atoms in the ion. Examples include nitrate (NO3-) and nitrite (NO2-).
What characteristics is shared by most simple polyatomic ions?
Most simple polyatomic ions have an overall charge due to the gain or loss of one or more electrons. They are typically made up of a small number of atoms bonded together and have a specific charge associated with their structure. These ions are generally stable and can participate in chemical reactions to form compounds.
What is the chemical formula for ammonium nitate?
The chemical formula for ammonium nitrate is NH4NO3.
What type of compound is Na2CO3?
Sodium carbonate (Na2CO3) is an inorganic compound classified as a salt. It is composed of sodium cations (Na+) and carbonate anions (CO3^2-).
What is the definition of cations anions monatomic ions and polyatomic ions?
Cations are positively charged ions formed by losing electrons. Anions are negatively charged ions formed by gaining electrons. Monatomic ions consist of a single atom with a positive or negative charge. Polyatomic ions are ions made up of two or more atoms covalently bonded together, carrying a net charge.
Are a vast majority of polyatomic ions cations?
No. Most polyatomic ions are anions.

Characteristic is shared by most simple polyatomic ions?
They are anions
What is a polyatamic ion?
A polyatomic ion is one that contains more than one atom. Many common anions are polyatomic, e.g. NO3-, SO42-, CO32-, PO43- Cations may be polyatomic, e.g NH4+, Hg22+
How are cations anions monoatomic ions and polyatomic ions the same and different?
Cations are positive ions (Fe2+, NH4+).Anions are negative ions (Cl-, (SO4)2-).Fe2+ is a monoatomic ion and (NH4)+ is a polyatomic Ion (contain more than one element).
What are the 2 kinds of ions?
There are at least two reasonable answers to this question: anions and cations or monatomic and polyatomic.
Is pottasium sulfate a covalent bond?
Potassium sulfate contains both covalent and ionic bonding. Potassium cations are bonded ionically to the polyatomic sulfate anions, and these anions are internally bonded covalently.
What are the elements that possess anions?
Only nonmetal elements can usually form monatomic anions, but some metallic elements, such as aluminum and iron, can form polyatomic anions that also include other very strongly electronegative elements, such as oxygen and fluorine.
Does oxygen form covalent bonds?
Yes, with itself in the diatomic molecule O2, in many polyatomic anions, and in oxides with most nonmetallic elements.

When does the end of a name of a negative ion in -ide?
Anions end in -ide if they are monatomic. Example: chlorine becomes "chloride." Polyatomic ions will have different suffixes.
