What is the molecular orbital that can be occupied by two electrons of a covalent bond?
The molecular orbital that can be occupied by two electrons of a covalent bond is the bonding molecular orbital. This orbital forms by the overlap of atomic orbitals in a constructive manner, leading to a decrease in energy when two electrons are placed in it.
What is the region around the nucleus where electrons are found?
The electron cloud. An electron cloud is a volume or region in the atom where it is likely to find or detect an electron. It is actually really hard to detect an electron because an atom is mostly empty space, electrons are orbiting the nucleus at almost the speed of light so they orbit really fast, the electrons are very tiny and may be point like since we don't really know the volume or size of the electron, and an atom in reality is 3 dimensional which the electron cloud and orbitals is 3 dimensional. Since electrons are so hard to detect then they would call this volume or region of the atom an electron cloud because the electron cloud is a volume or region where they know that electrons are likely to be there even if they are hard to find. Or maybe the electron cloud is where they can also know the different sub- orbitals or subshells of the electrons.
What kind of covalent bond is formed between the two oxygen atoms?
The answer to this question isn't completely understood because of the confusion surrounding obtained experimental evidence. O2 is paramagnetic (that is, it responds to a magnetic field) which implies it has unpaired electrons which also implies that O2 has a single bond. The Lewis structure of O2 with containing a single bond (with two unpaired electrons) is drawn below. ' O - O ' Obtained experimental bond length values on the other hand imply that O2 contains a double bond due to its shortened length. O = O Bottom and Top of O's must all have two electrons [dots] (along with the extra two unpaired electrons suggested in figure 1). [Tried adding the electrons [dots] to tops and bottoms of the oxygen atoms but when posted the dots rearranged in an ugly manner]
What does electronic configuration mean?
Electronic configuration is a term used in atomic physics and quantum chemistry. This is the manner in which electrons of a specific atom or molecule are distributed in an atomic or molecular orbital.
What happens to electrons when atoms form an ionic bond?
In an ionic bond, one or more electrons are transferred from one atom to another. The atom that loses one or more electrons becomes a positively charged ion, and the atom that gains one or more electrons becomes a negatively charged ion. The ionic bond is an electrostatic attraction between the oppositely charged ions.
How does the molecular order structure explain the magnetic properties of oxygen?
Molecular orbital theory predicts that ground state diatomic oxygen has two unpaired electrons (it is a diradical) which occupy its pi orbitals. These unpaired electrons produce a magnetic moment and are responsible for the paramagnetic property of diatomic oxygen.
What is the molecular orbital that can be occupied by two electrons of a covalent bond?
The molecular orbital that can be occupied by two electrons of a covalent bond is the bonding molecular orbital. This orbital forms by the overlap of atomic orbitals in a constructive manner, leading to a decrease in energy when two electrons are placed in it.
Which statement is not true of the atomic model of Bohr?
An electron has the same amount of energy in all orbitals this is not true because depending on how much enegry it has will depend on how many orbitals it has.An electron has the same amount of energy in all orbitals.
Do electrons surround the nucleus?
In simple models, yes. They do. In a more correct and more complex model, it is not possible to determine the exact position of an electron at any point, (as they are quantum) but areas of high probability for the electrons to be in exist, they are called orbitals, and yes, they surround the nucleus in a manner of speaking. In metallic bonding, the electrons de-localise from the orbitals, and they float around the substance. These electrons are not surrounding the nucleus.
Are electrons located only in specific shells around the nucleus of the atom?
Electrons are located in all the shells before the last shell but when doing equations and working things out, you only refer to the last shell. This is because the shells before the last shell are all full (the first one has only 2 electrons but the rest have 8) and only the outer shell electrons, known as valance electrons, react with other substances.
Why electron haven't elliptical path?
It doesn't make a lot of sense to talk about an electron's path, because electrons in atoms don't have paths period, whether circular, elliptical, or banana-shaped. They have orbitals, which despite the similarity in sound are not at all the same thing as orbits.
What is the Paths around the Nucleus called?
Electrons are said to occupy orbitals, around the atomic nucleus. They do not actually orbit in the manner that planets orbit the sun; they spread themselves out, as an electron cloud, and surround the nucleus rather than moving in an orbit.
How are protons electrons and neutrons distributed into space?
Protons and neutrons are found in the nucleus of an atom, which is a dense central core. Electrons, on the other hand, are distributed in a probabilistic manner within electron clouds or orbitals that surround the nucleus. The arrangement of these subatomic particles defines the structure and properties of the atom, with electrons occupying various energy levels based on their distance from the nucleus. This distribution creates a balance of forces, maintaining the stability of the atom.
What is the region around the nucleus where electrons are found?
The electron cloud. An electron cloud is a volume or region in the atom where it is likely to find or detect an electron. It is actually really hard to detect an electron because an atom is mostly empty space, electrons are orbiting the nucleus at almost the speed of light so they orbit really fast, the electrons are very tiny and may be point like since we don't really know the volume or size of the electron, and an atom in reality is 3 dimensional which the electron cloud and orbitals is 3 dimensional. Since electrons are so hard to detect then they would call this volume or region of the atom an electron cloud because the electron cloud is a volume or region where they know that electrons are likely to be there even if they are hard to find. Or maybe the electron cloud is where they can also know the different sub- orbitals or subshells of the electrons.
What is photoelectronic?
when a light is shown on a material.Electrons emitted in this manner can be called photo-electrons
What does it mean if a vessel is unpaired?
If a vessel is unpaired, it typically means that it is not part of a paired set with another vessel. This could refer to blood vessels, nerves, or similar anatomical structures that are normally found in pairs. In certain contexts, it could also mean that the vessel is not connected or associated with another vessel in a functional or anatomical manner.
In solid Conductors Electric current is the flow of?
In solid conductors, electric current is the flow of electrons moving through the material. These electrons move in a coordinated manner in response to an applied electric field, creating the flow of current.
