What is the electron configuration of an element?
The electron configuration of an element shows the number of electrons in their energy levels and orbitals. For example, the electron configuration of a neutral magnesium atom, Mg, with 12 electrons, is 1s22s22p63s2. This means that there are two electrons in the s orbital of the first energy level, two electrons in the s orbital and six electrons in the p orbital of the second energy level, and two electrons in the s orbital of the third energy level. The number in front of each letter represents the energy level, the letter represents the orbital, and the superscripts represent the number of electrons in the orbital.
What is electronic shells?
A shell surrounding the nucleus of an atom containing electrons.
Explain the relationship between electrons orbitals and energy levels?
Briefly:The electrons are in orbitals, each orbital can take two electrons and each electron would have an opposite spin. Orbitals can have no electrons, one electron or be filled with two electrons.Orbitals are arranged in energy levels. However, even in the same energy level different orbitals will have different energy despite being in the same main energy level.The energy level nearest the nucleus has 1 orbital: 1sThe next energy level, the second energy level has four orbitals: 2s and three p orbitals. The 2p orbitals have more energy than the 2s orbital. The third energy level has 3s x1; 3p x 3 and 3d x 5 however, the 3d orbitals have an energy which actually places them in the fourth energy level between 4s and 4p. It gets complicated.
Is it easier to remove an electron from the outer energy level than from one closer to the nucleus?
Think of it as like trying to lift a heavy stone up out of a conical pit. The nucleus is down at the bottom of the pit. It takes more work (energy) to remove the stones (electrons) that are deeper in the pit (closer to the nucleus). Remember that the lower numbered shells are lower (deeper) in the pit, and you won't go wrong.
What is the first shell closest to the nucleus?
The K shell is first shell closest to the nucleus.
An electrons path around the nucleus defines its?
An electron's path around the nucleus defines it's energy level.
What is the electron energy level closet to the nucleus of an atom?
The electron energy level closest to the4 nucleus is around 25.4 ev. and the radius is around 7.5 nanometers for an electron around a proton.
What statement accurately represents the arrangement of electrons in bohr's?
Electrons travel around the nucleus in fixed energy levels with energies that vary from level to level
Element with a 3- charge in the 4th energy?
An element with a 3- charge in the 4th energy would have a strong, stable nucleus with a strong nuclear force holding the protons and neutrons together. This element would also have a strong, repulsive electrostatic force between the protons in the nucleus and the electrons in the 4th energy level.
How are electrons arranged in the atom?
Electrons are arranged around the atomic nucleus forming the electron clouds.
What is the region where electrons are found?
This is the electron cloud, around the atomic nucleus.
What is a energy level?
The energy possessed by an electron at a set of distance from the nucleus.
Why is the lowest energy level of an atomic orbital the one farthest from the nucleus?
The lowest energy level is NOT farthest from the nucleus. It is closest to the nucleus. The energy levels of an atom are expressed as negative numbers. In an energy level diagram the level nearest the nucleus will be the largest negative number. But again this means it is the lowest energy. For example, -8 is larger then -13.
In an atom an electron that is close to the nucleus is on the highest enegry level?
No. The greater distance from the nucleus the more energy an electron has.
What are the region around the nucleus where the electrons are located called?
electron cloud
How many element are located in the second energy level if an atom has 7 element?
5 atoms are located in the second energy level if the first energy level has 7.
What scientist discovered that atoms have energy level?
The scientist who discovered that atoms have an energy level is Niels Bohr in 1913. According to his model electrons move around the nucleus much the same as the planets rotate around the sun.
