Which substance was not present in Earth's primitive atmosphere?
Oxygen was not found in the atmosphere of primitive Earth. It is so reactive that it became locked up in compounds at the time of Earths formation. These compounds were varied, but the bulk of them were mineral oxides, silicates, carbon dioxide and water. Free oxygen entered the atmosphere only after the development of blue-green algae, which produced oxygen from carbon dioxide.
Why is the bond in beryllium chloride covalent rather than ionic?
The Be2+ cation is smaller in size (being above the rest of the group 2 elements) and hence has high charge density. This enables it to easily polarise the comparatively larger Cl- anion, which results in a covalent characteristic of the compound. Dative bonding (a special type of covalent bond in which the shared electrons come from one of the atoms only) occurs in the compound and BeCl2 usually occurs as a dimer i.e Be2Cl4 (polymeric type) based on the linear molecular structure of BeCl2. Polarisation occurs between a small cation with high charge density and a larger anion. Since the size of the cations of the group 2 elements increases down the group (more atomic radius), charge density around the cation decreases and hence their ability to polarise the Cl- also decreases, resulting in an ionic compound.
Are hydrocarbons in the carboxyl group?
This wording of this question sounds like you may be confused. In the term "carboxyl group", group refers to a specific group of atoms (COOH), not to a group of similar types of compounds. Since hydrocarbons by definition contain only carbon and hydrogen, a hydrocarbon cannot contain a carboxyl group.
What number of protons does carbon atom become unstable?
Carbon atom contains only 6 protons. It is become unstable when number of neutrons are increasing.
What is formed when a fossil fuel is burned in plenty of air?
only carbon dioxide
What elements are in ionic compounds?
Ionic compounds only occur between a nonmetal and metal, also Halogens and The Carbon Family do not form Ionic bonds.
Does carbon form four ionic bonds in its compounds carbon forms four ionic bonds in its compounds?
carbon forms only covalent bond.It shares its electrons with some other element. Ex. CH4 methane
What formula of the ionic compound formed by the elements lithium and oxygen?
The electronegativity difference between carbon and oxygen is small. So they will form only covalent compounds and not ionic compounds. CO (carbon monoxide) and CO2 (carbon dioxide) are the two covalent compounds formed. In addition they can form ions like bicarbonate ion (HCO3-) and carbonate ion (CO32-) where there is covalent bond (and not ionic) between carbon and oxygen.
What is the ionic compound for nitrogen and hydrogen?
Nitrogen and hydrogen don't form ionic compounds. they form only covalent compounds as in ammonia (NH3) or hydrazine (H2N-NH2) etc
Can someone make as many ionic and polyatomic compounds with hydrogen nitrogen oxygen chlorine sodium and calcium?
- If you think only to isolated elements all these elements can form polyatomic compounds.- Calcium and sodium form ionic compounds.- H, N, O, Cl can form ionic or covalent compouds.
What are the two types of binary compounds?
Type 1 binary ionic compounds are those in which the cation has only one form, or charge. Type 2 binary ionic compounds are those in which the cation can have multiple forms.
Is CaS a covalent compound?
Ca (calcium) is an element, not a compound. and it can only form ionic compounds.
What is calcium carbon oxygen?
There is no compound CaCO. Since carbon and oxygen are non-metals, the only compounds they are likely to form with calcium are ionic compounds. So that would require making an anion out of carbon and oxygen. The only polyatomic anion that you can get from carbon and oxygen is carbonate, CO32-. So the calcium carbon oxygen that you might be referring to is calcium carbonate, CaCO3.
What area of the periodic table contains elements that form cation in ionic compounds?
Hydrogen only participates in ionic bonds.
Is concrete made of ionic compounds or covalent compounds?
Concrete is made of covalent compounds with strong bonds. Non-metals and metals form ionic compounds only.
What type of ions does titanium form?
Silicon does not form ionic compounds containing Si cations. It is after all a non-metal. There are some "odd" compounds called silicides binary compounds of metals with silicon but generally these are not ionic, only those with the more reactive metals have ionic nature, silicon forming cluster anions (Zintl compounds) such as Si44- (isoelectronic with P4 molecule)
What cations always form soluble compounds?
Cations don't always form soluble compounds. In general, ionic compounds are soluble in very polar solvents such as water and insoluble in nonpolar solvents because the charged ions can be solvated only by polar solvents. Some ionic compounds are insoluble even in water, however.
