When do orbitals start getting filled?
after the s orbital of the next highest energy level
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.
Why does 4s orbital start filling while 3p orbital is empty?
The electrons fill in the lowest energy orbital that is available. Electrons in the 4s orbital have a lower energy level than electrons in the 3p orbital, so the 4s orbitals are filled with electrons first.
What is a good energy pyramid for a taiga?
It can start with the producers. Like trees, short grasses and shrubs. Then it goes to the primary consumer. These include rabbits, deer, caribou, and other things that eat these plants. After that it will go to the secondary consumer. These are weasels, wolverines, and other things that eat the primary consumers. After that it goes to the tetrieary consumer (spelling is off). These include bears, birds of prey, large predator cats, and other things that eat the secondary consumers. Be sure to include a decomposer at the top to finish it off, and be sure to go down in the energy consumption at each level.
How many energy shells does silver have?
Lead has six energy levels. It has an atomic number of 82 which is also equivalent to the number of protons and electrons.
Facts about energy pyramid?
Energy pyramids start with a producer at the bottom . Then it has the consumers at the top.
Why do electrons start filling the 1st energy level of an atom before the 2nd?
At the ground state, it is easier to fill the first energy level than the second because the second energy level is located farther away and takes more energy to get there.
What is the energy pyramid of the savanna biome?
Well if you start at the top it's lion zebra grass.
When do d orbital start getting filled?
after the s orbital of the next highest energy level
When do orbitals start getting filled?
after the s orbital of the next highest energy level
When did pyramid building start?
1764
What is the theory of atomic energy?
That's a big topic for Wikianswers, suggest you go to Wikipedia as a first resort, and then start reading some simple high school level books on the subject.
When you finish campan in bf3 what level do you start as in multiplayer?
You start as level 0. When you start multiplayer, you will see there is no rank on your name, this means you will need to gain your first rank as 1.
What happens once an atom has full s and p orbitals in its outermost energy level?
Depending on what the level is, it may start filling d orbitals, or start on a new shell with s orbitals available.
What is the first determining factor in the START triage system?
level of conscouseness
