Solid sodium is a metal, there is a lattice of sodium atoms with a "cloud" or sea of electrons delocalised across it.#
Polyatomic number are ions made up of more than one atomic element
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, Methane (CH4) is not a polyatomic ion. It doesn't have a charge, therefore it can't be an ion. It's considered a hydrocarbon.
A polyatomic Radical is a atom that differs from other because it has come into contact with a massive energy force and fused it into a different form
Oxygen
Sodium hydroxide (NaOH) is polyatomic (contain atoms of Na, O and H).
Sodium perbromate is not a polyatomic ion. It is an ionic compound formed by combining sodium (Na +1 ) ions with perbromate ions (BrO4 -1). Perbromate by itself would be a polyatomic ion.
The polyatomic anions in sodium sulphate have the formula SO4-2, while the polyatomic anions in sodium thiosulphate have the formula S2O3-2.
The polyatomic ion name for NaClO is Sodium Hypochlorite
sodium phosphate Na3PO4
NaOH is Sodium Hydroxide.
HCO3- is the polyatomic ion with which sodium bonds. It is the bicarbonate ion.
Na2BeO2 is the chemical formula for "sodium beryllate", a salt with sodium cations and polyatomic beryllate anions.
No, Sulfur Trixoxide SO3 is a molecule. There is a polyatomic ion called the Sulphite ion which has the formula SO32-.
A polyatomic ion is charged and will form ionic bonds; for example, the sulfate ion SO42- forms many compounds, such as sodium sulfate. The bonds holding polyatomic ions together are covalent.
Baking soda is sodium bi-carbonate. Or sodium hydrogen carbonate. Its formula is NaHCO3. It is a union of sodium and the bi-carbonate polyatomic ion.
Sodium Hydroxide. the OH in NaOH is a polyatomic ion and has a negative charge.
