Principal energy level 1 of an atom contains an electron with the lowest energy why?
The principal energy level 1 is the closest energy level to the nucleus, resulting in the electron being held most tightly by the nucleus, thus having the lowest energy. This electron is in the lowest energy state possible due to the electrostatic attraction between the negatively charged electron and the positively charged nucleus.
The arrangement of electrons in an atom is called?
A unit of matter, the smallest unit of an element, having all the characteristics of that element and consisting of a dense, central, positively charged nucleus surrounded by a system of electrons. The entire structure has an approximate diameter of 10 -8 centimeter and characteristically remains undivided in chemical reactions except for limited removal, transfer, or exchange of certain electrons.
What is the relationship between an electron's location and the energy it has?
An electron can be located in any of several energy levels around the nucleus of an atom. Usually, an electron will occupy the "ground state," which is the lowest energy level available. Electrons can be thought of as being lazy, which means they don't want to work any harder than they have to; and occupying the ground state amounts to the path of least resistance. Occasionally, however, an electron can "bump up" to a higher energy level. It can do this by absorbing energy from an outside source, such as an electrical current. It will occupy this higher energy level for a certain amount of time, then drop back to its ground state, releasing that same energy it absorbed to get there. The amount of energy absorbed is called a quantum. Often, the electron will release that quantum of energy as a photon, which is a "bundle" of light. Billions of photons can be a light that you can see, and this is how neon lights and glow sticks work. So the higher an energy level an electron occupies, the higher its energy.
An element is selective in the frequency of light it will absorb This selectivity is due to its?
Every element can only absorb certain wavelengths of light because of how the electrons are positioned around the nucleus. There is a fixed number of energy levels that each electron may move to, and each move will only occur if a specific amount of energy is absorbed. Thus each element, having differing electron orbital states can only absorb certain frequencies of light.
How many electrons are in argons cloud?
Argon is atomic number 18. It would therefore have 18 protons. Having 18 protons would mean that Argon must also have 18 electrons.
Is a duplet electron considered stable?
A duplet electron configuration is considered stable, as it corresponds to having two electrons in the outer energy level, which is the most stable configuration for elements in the first period. Elements like helium achieve a duplet electron configuration and are relatively stable due to their full outermost energy level.
What is the electron configuration called that has 18 electrons in the outer energy level?
Noble gasAn atom's atomic number tells us its number of protons and electrons. Checking the periodic table for the element having an atomic number of 18, we find that it is argon. Argon's electron configuration is 1s2 2s2 2p6 3s2 3p6, which has all of its energy levels filled.
General electronic configuration of group having low ionisation energy?
The general electron configuration of the group having the lowest ionization energy is [Noble gas configuration]xs1. In this case, x is the principal quantum number of the valance electron. The noble gas configuration may either be written out in full or denoted by the noble gas' atomic symbol in brackets (ie [Ne]).
What is the excited state of phosphorus?
The excited state of phosphorus occurs when an electron is promoted to a higher energy level within its electron configuration. This results in phosphorus having more energy than in its ground state, which can lead to the emission of light or other forms of energy when the electron returns to its original energy level.
How is an elements period related to its its electron confuguation?
An element's period is related to its electron configuration by indicating the energy level of its outermost electrons. Each period corresponds to a new energy level, with elements in the same period having electrons in the same principal energy level. Electron configuration describes the arrangement of electrons in these energy levels, with each period accommodating a specific number of electron shells.
What would the electron configuration of atoms of a noble gas be?
The electron configuration of noble gases follows the octet rule, where the outermost energy level is fully filled. For example, the electron configuration of a noble gas like neon (Ne) would be 1s2 2s2 2p6. This configuration signifies a stable energy state with eight valence electrons.
Bohr model of the element lead?
The Bohr model describes lead as having a nucleus at the center with 82 protons and usually 125 neutrons. Electrons orbit the nucleus in energy levels or shells. The electron configuration for lead is [Xe] 4f14 5d10 6s2 6p2.
Why the metal is very reactive?
Metals , generally, have electronic configuration: with outermost electron having 1,2 or 3. Since, they can easily attain noble gas configuration to attain stability; they readily loose electron.
In forming the molecule HF the F atom attains the electron configuration of?
In forming the molecule HF, the fluorine (F) atom attains the electron configuration of a stable octet by sharing one electron with hydrogen (H) to form a single covalent bond. This results in fluorine having a full outer shell with a total of eight electrons, achieving a stable electron configuration.
What is the noble gas that has atoms in the ground state with the same electron configuration as the nitrogen in a moleculoe of isocyanic acid?
The noble gas with atoms in the ground state having the same electron configuration as nitrogen in a molecule of isocyanic acid is Neon. Both nitrogen and neon have the electron configuration of 1s² 2s² 2p³ in their ground state.
Ion electron configuration for beryllium?
The electron configuration for the beryllium ion (Be^2+) is 1s^2 2s^2. Beryllium typically has an electron configuration of 1s^2 2s^2, but when it loses two electrons to become the Be^2+ ion, it loses the two outermost 2s electrons.
What is the difference between a stable and unstable electronic configuration?
Stable electronic configuration is when the valence shell of an element is completely filled (8 electrons) whereas unstable electronic configuration is when the valence shell of an element is not completely filled
