Answer: In h2o there is hydrogen bonding because oxygen has a high electronegativity(only second to flourine). so, the hydrogen atoms from other molecules of water forms a hydrogen bonds with oxygen resulting in intermolecular hydrogen bonding. therefore at room temperature h2o is a liquid and h2s is a gas.
Therefore due to more number of atoms associated per molecule, sulphur exists as a solid whereas oxygen exists as a gas. Thanks. Sulphur has a vacant D orbital so it can form Bond with other element are itself as compared to oxygen. Also O2 molecule exist where as sulphur is exist as S8 solid.
Sulfur occurs naturally as the element, often in volcanic areas. This has traditionally been a major source for human use. It is also widely found in many minerals including iron pyrites, galena, gypsum and Epsom salts. Elemental sulfur was once commercially recovered from wells by the Frasch process.
Probably because Sulfur forms single bonds rather than double bonds as an element. It exists as disulfide but as an ion with two negative charges, not as an element. Oxygen does not have strong Vander Wall forces among atoms and so it exists as a gas at room temperature. Sulfur exists in many allotropic forms.
Solid oxygen forms at normal atmospheric pressure at a temperature below 54.36 K (−218.79 °C, −361.82 °F). Oxygen is the only simple diatomic molecule (and one of the few molecules in general) to carry a magnetic moment.
Oxygen is available as O2 not as O because pure oxygen is highly reactive it will combine with anything to form oxides,disconnected atoms have a very strong tendency to form bonds. Thus oxygen is always available as O2 but it is hard to found a pure oxygen atom.
Originally Answered: Why is oxygen in chemical equations written as O2, when the element itself is just O? A single oxygen atom (O) is not stable. To become stable, it must be combined with another oxygen atom to create oxygen gas (O2) or two more oxygen atoms too create ozone (O3).
Under standard conditions iodine is a dark blue-black solid. As a gas, iodine is a purple vapor. Iodine is a fairly active element, but is somewhat less active than the other halogens above it in the periodic table which include bromine, chlorine, and fluorine. Iodine can form compounds with many elements.
If you are referring to "oxygen gas" it's because the chemical O2 (also known as "oxygen gas") exists as the state of matter known as "gas" at room temperature. Oxygen fills the entire space in the container in which it is filled. Oxygen has no definite shape. Oxygen has no definite volume.
Oxygen is an element that can be a solid, liquid or gas depending on its temperature and pressure. In the atmosphere it is found as a gas, more specifically, a diatomic gas. This means that two oxygen atoms are connected together in a covalent double bond.
Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium.
Fire is made up of many different substances, so it is not an element. For the most part, fire is a mixture of hot gases. Flames are the result of a chemical reaction, primarily between oxygen in the air and a fuel, such as wood or propane. Or, you can say it's mostly gas, with a smaller amount of plasma.
Smoke is a collection of tiny solid, liquid and gas particles. Although smoke can contain hundreds of different chemicals and fumes, visible smoke is mostly carbon (soot), tar, oils and ash. Smoke occurs when there is incomplete combustion (not enough oxygen to burn the fuel completely).
Neon is a chemical element with the symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air.
As we move from fluorine to iodine, the electrons are further from the nuclei so the electron clouds can more easily distort. The London dispersion forces become progressively stronger. At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases.
Contrary to popular myth, hyperventilating air at ordinary pressures never causes oxygen toxicity (the dizziness is due to CO2 levels dropping too low), but breathing oxygen at pressures of 0.5 bar or more (roughly two and a half times normal) for more than 16 hours can lead to irreversible lung damage and, eventually,
Originally Answered: What are examples of monatomic gases? The only chemical elements which are stable single atom molecules at standard temperature and pressure (STP) are the noble gases. These are helium, neon, argon, krypton, xenon and radon.
HOFBrINCl (hydrogen, oxygen, fluorine, bromine, iodine, nitrogen, and chlorine). They also form a 7 (in addition to hydrogen) in the periodic table. The diatomic elements have a subscript of 2 when the elements are by themselves in a chemical equation. It is formed by electrical discharge in oxygen.
Diatomic elements are special as the atoms that form it do not like to be alone. That is, you will never find a nitrogen or fluorine atom, for example, hanging out solo. Rather, these atoms will always be paired together because they need to pool resources to have enough electrons.
Elements can be made of one atom, like He, or be elemental molecules, such as hydrogen (H2), oxygen (O2), chlorine (Cl2), ozone (O3), and sulfur (S8). Some elements are monatomic, meaning they are made of a single (mon-) atom (-atomic) in their molecular form.
There are seven diatomic elements: hydrogen, nitrogen, oxygen, fluorine, chlorine, iodine, bromine.
Sulfur is a non-metal because it's not placed in metal group in the periodic table. Sulfur is described as a non-metal since it is reliable with the 3 physical properties recorded for nonmetals.
Diatomic sulfur, , exists only at high temperatures, much higher than are commonly found. Sulfur at room temperature and pressure is octatomic, . Sulfur can be *divalent*, which means that it has an oxidation state of +/-2.
Oxygen generally exists as a diatomic molecule in the atmosphere when it is not combined with any other element. It forms the molecule O2 because in that configuration, it has its lowest energy level when uncombined. In the standard model of the oxygen molecule, each oxygen atom shares two pairs of electrons.
It is monatomic. Helium is a member of the noble gases which means it has a filled outer shell of electrons. It is monatomic. Helium is a member of the noble gases which means it has a filled outer shell of electrons.
