What element has the electron configuration of Kr 5s2 4d10 5p3?
Group 1- as the configuration is ns1. The Kr in the question indicates the Krypton core. The 5s1 is the clue - the period number is the same as the principal quantum number (in this case 5) so the element is in group 1 and period 5 - so it is rubidium.
What does the principal quantum number tell you?
The principal quantum number is the level of the most energetic electrons in an atom. It also corresponds to which period the element is in on the periodic table. For example, barium has a principal quantum number of 6 because its valence electrons are in level 6, and the element is in period 6.
What is a principal quantam number?
The principal quantum number refers to the electron shell, or energy. Refer to the related link to read a Wikipedia article about quantum numbers.
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]).
How many electron shells does radium have?
Rubidium has 5 electron shells. The electron configuration of rubidium is [Kr]5s1.
What is the largest principal quantum number in the ground state electron configuration of iodine?
5
In which period and group is the element whose electron configuration is Kr5s1?
Group 1- as the configuration is ns1. The Kr in the question indicates the Krypton core. The 5s1 is the clue - the period number is the same as the principal quantum number (in this case 5) so the element is in group 1 and period 5 - so it is rubidium.
What is the principal quantum number value for the highest energy electron in carbon atomic number 6?
The principal quantum number for the highest energy electron in carbon would be 2. It is easy to spot this, since carbon exists in row 2 of the period table. The row in which an element resides always shows the highest value of n, or the principal quantum number, that an electron can reside in.
What specific field of science does an electron configuration apply to?
The specific field of science that an electron configuration applies to is quantum physics. Electron Configuration refers to the distribution of electrons in an atom.
What is the term used to label the energy level of electron?
Principal quantum numbers (n).
What element has the electron configuration of Kr 5s2 4d10 5p3?
Group 1- as the configuration is ns1. The Kr in the question indicates the Krypton core. The 5s1 is the clue - the period number is the same as the principal quantum number (in this case 5) so the element is in group 1 and period 5 - so it is rubidium.
What does the n represent in the quantum model of the atom?
n is the principal quantum number and represents the energy level or electron shell in which an electron resides. For example - Say you have an Oxygen atom, which has 8 electrons. It's electron configuration is 1s2 2s2 2p4. The 2 in 2p4 is the principle quantum number, n. The s is another term dealing with angular momentum and the 4 is the number of electrons.
What does the principal quantum number tell you?
The principal quantum number is the level of the most energetic electrons in an atom. It also corresponds to which period the element is in on the periodic table. For example, barium has a principal quantum number of 6 because its valence electrons are in level 6, and the element is in period 6.
