How many electrons can be held in the second energy level of atoms and how can this be determined?
first energy level contains only S shell that can accomadate 2 electrons where as 2nd energy level contains S shell and P shell as well which can accomadate 2 and 6(3X2) electrons respectively..so the answer is 8 for 2nd energy level. (or) No.of electrons in any main energy level = 2n2 Here n = orbit (or energy level) number In our question , n = 2 No.of electrons in 2nd energy level = 2(2)2 = 8
What is the maximum number of electron found in the fourth main shell of an atom?
Use the formula n2 = max. number of electrons in shell. 42 = 16. 16 electrons.
Describe Why a stairway is a good model for energy levels in an atom?
A stairway is a good model for the energy levels in an atom because there is a 'main floor' ( the nucleus ) and steps ( the energy levels ). The nucleus is the start of the stairway of the energy levels, and the other energy levels go off of the nucleus. The first energy level can hold 2 electrons, the second energy level can hold 8. The third energy level can hold 18, and the fourth energy level can hold 32 electrons. In order for an element to be as stable as a noble gas, the outermost energy level has to be full, so sometimes an atom will gain or lose electrons to fill it's outer energy level. Other times it might share electrons with other atoms, so that they don't have to gain or lose a lot of electrons. An example of this would be H2O ( water ). There is one oxygen atom with two hydrogen atoms connected to it, and sharing their electrons with each other.
Identify How many electrons the third energy level can hold and explain why this is the case?
For each level (main quantum number) number "n", there are 2 times n squared electrons. The reasons are related to the Pauli Exclusion Principle, meaning that no two electrons can have the same values for all four quantum numbers.
What is the source of the energy that produces the chemiosmotic gradient in mitochondria?
Main fuel is glucose. It is oxidized using oxygen
What is the main energy level that can hold only two electrons?
first energy level.
What is the maximum number of electrons in the main energy level four?
32 electrons
How many electrons are in the main energy level if n is equal to 1?
twenty
How many electrons does fluorine atom have in its outermost unexcited main energy level?
Fluorine has 7 valence electrons.
How many electrons can be held in the second energy level of atoms and how can this be determined?

Why is it significant that valence electrons are located in the outermost energy level of an atom?
The valence electrons are the electrons that undergo chemical bonding in the main group or representative elements.
What element has one main energy level?
Helium has two electrons which completely fills the first principal quantum level.
How many electrons are needed to fill the third main energy level if it already contains 8?
10
Valence electrons are those?
Valence electrons are those that exist in the highest main energy level in the last shell of an atom.
What is the maximum number of electron found in the fourth main shell of an atom?
Use the formula n2 = max. number of electrons in shell. 42 = 16. 16 electrons.
List the total number of electrons needed to fully occupy each main energy level?
I'm the biggest boss in town guess UBA heheh
