How many electrons are in the outermost energy level of a chloride ion (Cl and ndash) in table salt?
A chloride ion (Cl⁻) has gained one electron compared to a neutral chlorine atom, which originally has seven valence electrons in its outermost energy level. Therefore, as a chloride ion, it has eight electrons in its outermost energy level. This configuration is stable and corresponds to the noble gas configuration of argon.
According to quantum mechanics what is the maximum number of electrons that can occupy the third energy level in a ground state atom?
The first level can hold 2, the second can hold 8, and the third can hold 18 electrons. However, the outer level never holds more than 8; therefore an atom containing only 3 levels will have only 8 in the 3rd level.
How many neutrons does chloride have?
Chlorine atom has 17 electrons. It is readily accepting an electron from another atom to obtain its stable electron configuration (of argon). A chloride ion has 18 electrons.
How many electrons are in the third level of magnesium?
In magnesium, the third energy level can hold a maximum of 18 electrons. However, in a ground state magnesium atom, only 2 electrons are present in the third energy level, as magnesium has 12 electrons total - 2 in the first level and 8 in the second level.
What number indicates the energy level of an atom's valence electrons?
The energy level of an atom's valence electrons is indicated by the principal quantum number, denoted as ( n ). This number can range from 1 to higher integers, with each successive number corresponding to a higher energy level and distance from the nucleus. For example, the valence electrons in the outermost shell of an atom with a principal quantum number of 3 would be in the third energy level.
What is the number of electrons at energy levels in chloride atom?
Chloride is an ion, not an atom. It has 18 electrons which are 2, 8, 8 in the first three quantum levels respectively.
How many electrons are in the outer energy level of a chloride atom?
In the question, it should be either "chlorine atom" or "chloride ion". Chlorine atom has 7 valence electrons. Chloride ion has 8 valence electrons.
How many electrons are in the third principal level of a chromium atom?
There are eight electrons in the third level of a chromium atom.There are four level in the chromium atom, and the fourth level, unfilled, contains 6 out of 18 electrons, in the neutral, non-ionized atom.
How many electrons are the third energy level of a calcium atom?
There are 8 electrons in the third energy level of a calcium atom.
How many electrons can an atom's third energy level hold?
The third energy level of an atom can hold eight electrons.
How many electrons does an argon atom have in each level?
An argon atom has 2 electrons in its first energy level, 8 electrons in its second energy level, and 8 electrons in its third energy level.
How many electrons are in a chloride ion's outermost energy level?
The chloride ion (Cl-) has 8 electrons on the outermost energy level.
The 3rd level of an atom can hold how many electronss?
The third level of an atom can hold a maximum of 18 electrons.
How many are in the third level if an atom has sixteen electrons?
This would be sulfur, and the third level has 6 electrons. See the diagram linked below
What is the neutral atom that has its first two energy levels filled has 1 electrons in its third energy level and has no other electrons?
This atom would be lithium (Li). It has 3 electrons, with 2 electrons in the first energy level and 1 electron in the third energy level.
What is the number of electrons that fit in an atom's third energy level?
8
How many electrons are in the third energy level of magnesium atom?
There are 2 electrons in the first energy level, 8 electrons in the second energy level, and 2 electrons in the third energy level of a magnesium atom, as it has an atomic number of 12 with electron configuration 2-8-2.
