A polyatomic ion is similar to a covalent compound in as much as the atoms in the polyatomic ion are covalently bound, and it is a compound, but it has a charge. Hence it is an ION.
I'm not sure what you mean by "purely covalent", since the ionic-vs-covalent distinction is expressed in terms of electronegativity, which can take a range of values (higher values = more ionic). CO is very much a covalent compound though.
Sulfide ion (S2-) contains two sulfur atoms while sulfate ion (SO4^2-) consists of one sulfur atom and four oxygen atoms. Sulfide ions typically have a charge of -2, while sulfate ions have a charge of -2 as well.
Covalent is two non-metals sharing electrons while Ionic is a metal and a nonmetal where one takes an electron and changes both of the elements charges for example Nitrogen and Oxygen would be covalent while Iron and Oxygen would be Ionic
Is BO ionic or molecular The compound BO (boron monoxide) is molecular (covalent), not ionic. Here’s why: Boron (B) is a metalloid and oxygen (O) is a nonmetal. Ionic compounds usually form between a metal + nonmetal (with full electron transfer). In BO, electrons are shared between boron and oxygen → this is a covalent bond. ✅ Conclusion: BO is a molecular (covalent) compound, not ionic. If you want, I can explain how to quickly tell ionic vs molecular for any formula 👍 Is glucose molecular or ionic Glucose (C₆H₁₂O₆) is a molecular (covalent) compound, not ionic. Here’s why: It is made only of nonmetals: carbon (C), hydrogen (H), and oxygen (O). These atoms share electrons to form covalent bonds rather than transferring them. Glucose exists as discrete molecules, not as a lattice of ions. ✅ Conclusion: Glucose is molecular (covalent). If you want, I can show you a quick rule to identify ionic vs molecular in seconds. Is HClO4 ionic or molecular HClO₄ (perchloric acid) is a molecular (covalent) compound. Here’s the reasoning: It is composed entirely of nonmetals: hydrogen (H), chlorine (Cl), and oxygen (O). These atoms form covalent bonds by sharing electrons. As a pure substance, HClO₄ exists as molecules, not ions. ⚠️ Important note: When dissolved in water, HClO₄ is a strong acid and ionizes completely into H⁺ and ClO₄⁻ ions. But that doesn’t make it ionic as a compound—it’s still molecular in its pure form. ✅ Conclusion: HClO₄ is molecular (covalent). Is perchloric acid a ionic compound? No — perchloric acid (HClO₄) is not an ionic compound; it is molecular (covalent). Why: It’s made of nonmetals (H, Cl, O) → they share electrons → covalent bonds. As a pure substance, it exists as molecules, not a lattice of ions. But here’s the key detail: In water, perchloric acid is a strong acid, so it ionizes completely into H⁺ and ClO₄⁻. That means it behaves like an ionic solution, but the compound itself is still molecular. ✅ Final answer: Perchloric acid is molecular, not ionic. Is HNO3 a ionic compound No — HNO₃ (nitric acid) is not an ionic compound; it is molecular (covalent). Why: It consists of nonmetals (H, N, O), so the atoms share electrons → covalent bonds. In its pure form, it exists as molecules, not ions in a lattice. Important note: When dissolved in water, HNO₃ is a strong acid and ionizes completely into H⁺ and NO₃⁻. So it forms ions in solution, but the compound itself is still molecular. ✅ Conclusion: HNO₃ is molecular (covalent), not ionic. How do you work out eGFR? To work out eGFR (estimated glomerular filtration rate), you don’t calculate it with a simple formula by hand in most cases—it’s usually computed using standard equations based on lab values. 🔑 The key inputs are: Serum creatinine (from a blood test) Age Sex (Sometimes race, depending on the formula used) 📊 Most commonly used formula: CKD-EPI equation The modern standard is the CKD-EPI equation, which is a bit complex but looks like this: eGFR = 141 × min ( S c r k , 1 ) a × max ( S c r k , 1 ) − 1.209 × 0.993 Age × (sex factor) eGFR=141×min( k Scr ,1) a×max( k Scr ,1) −1.209×0.993 Age×(sex factor) Where: Scr = serum creatinine k = 0.7 (female) or 0.9 (male) a = −0.329 (female) or −0.411 (male) Sex factor = 1.018 if female, 1 if male 🧠 What it means: eGFR estimates how well your kidneys are filtering blood Units: mL/min/1.73 m² Higher = better kidney function 📈 Quick interpretation: ≥90 → Normal 60–89 → Mildly reduced 30–59 → Moderate kidney disease 15–29 → Severe
An Ionic bond is one where an element gives away electrons to another, forming Ions. It usually occurs between metals and nonmetals. Another way to tell is if the electronegativity difference between the elements is greater than 2.0 then it is an ionic bond. A covalent bond is one where the elements share electrons with one another. It usually occurs between nonmetals. If the electronegativity difference between the elements is 2.0 or less it is a covalent bond.
I'm not sure what you mean by "purely covalent", since the ionic-vs-covalent distinction is expressed in terms of electronegativity, which can take a range of values (higher values = more ionic). CO is very much a covalent compound though.

A pure element or a pure compound are homogeneous.
North Viet Army (NVA)/Viet Cong (VC) vs Allies.
Sulfide ion (S2-) contains two sulfur atoms while sulfate ion (SO4^2-) consists of one sulfur atom and four oxygen atoms. Sulfide ions typically have a charge of -2, while sulfate ions have a charge of -2 as well.
I think what you mean is Mg(OH)2 vs MgO2H2. This is an ionic compound because it has a metal (magnesium). In it, Mg+2 is the cation (positive ion) and OH- is the anion. Because an ionic compound must have a zero net charge, there needs to be two OH- ions to cancel the +2 charge of the magnesium. so in the first formula it is shown that there are two OH- ions, but the second one is incorrect because OH is one ion and the elements are not separately written like that in an ionic compounds formula. hope this helps

Consumer vs producer is not an applicable categorization for Ammonia. Ammonia is a substance, a chemical compound.
