Is it true that electrons are arranged in different energy levels in an atom?
It simply means that electrons can only have certain energies. These "levels" are often in terms of n, such as n1, n2, n3, and so on. Let's say that n1=1000 eV (a unit for energy) and n2=2000 eV. It would be impossible for an electron in an atom to have any energy between those two values. This follows true for any energy level; this can be shown better like this: there can be no electron energy found between nx and nx+1 when the electron is in an atom.
Define free radical?
a group of atoms ith an unpaire electron
Define negative charge without using mass of electron?
Mass and charge are not connected. Negative charge is the charge carried by an electron.
Define Polarizability What is polarizability?
It is a measure of how easily an electron cloud is distorted by an electric field. Electron cloud will belong to atom, molecule or Ion. It is the quantitative measurement of the extent to which the electronic cloud can be polarized
What are the different areas of an electron cloud called?
The different areas of an electron cloud are called electron orbitals. These orbitals define the regions in an atom where electrons are most likely to be found. They are categorized by different shapes and energies based on quantum mechanics.
Do quantum numbers define the energy states and the orbitals available to an electron?
Yes, quantum numbers define the energy states and the orbitals available to an electron. The principal quantum number (n) determines the energy level or shell of an electron, the azimuthal quantum number (l) determines the shape or orbital type, the magnetic quantum number (m) determines the orientation of the orbital, and the spin quantum number (+1/2 or -1/2) determines the spin state of the electron. Together, these quantum numbers provide a complete description of the electron's state within an atom.
What the smallest particle in a atom?
Size on the scale of atoms is very hard to define. The electron has zero mass. Quarks have varying amounts of mass.
Define ionization energy of an element?
Ionization energy is the amount of energy required to remove one electron from a neutral atom in the gaseous state. It is a measure of how tightly the electron is held by the nucleus of the atom. Elements with higher ionization energies require more energy to remove an electron and are less likely to form ions.
What is the significance of the boundary of an electron cloud?
The boundary of an electron cloud represents the region where there is a high probability of finding an electron. It helps define the size and shape of the atom or molecule, influencing its chemical properties and interactions with other atoms. The boundary also signifies the extent of the electron's influence on the surrounding environment.
Define electron volt?
An electron volt (eV) is a unit of energy equal to the energy gained by an electron as it moves through a potential difference of one volt. It is commonly used in atomic and subatomic physics to describe the energy of particles at the atomic and molecular scale.
How does Lewis define acids and bases?
Lewis defined acids as substances that are electron pair acceptors, and bases as substances that are electron pair donors. According to Lewis, acids and bases react by sharing an electron pair to form coordinate covalent bonds.
Why is it difficult to observe vacuoles mitochondria ribosomes endoplasmic reticulum?
Because they are ultra microscopic! you can tract them if you have high resolution microscopes such as electron microscopes.
The highly probable location of an electron withthin the atom is an?
The highly probable location of an electron within an atom is described by its orbital, which is a three-dimensional region where there is a high likelihood of finding the electron. These orbitals are often visualized as fuzzy clouds surrounding the nucleus, depicting the probability distribution of where the electron is likely to be located. The specific shape and size of the orbital depend on the quantum numbers that define its characteristics.
