What else can I help you with?
The first element with an electron in the second energy level?
The first element with an electron in the second energy level is lithium. Lithium has three electrons, with two in the first energy level and one in the second energy level.
What element has atoms with only one completely filled principal energy level?
undiscovered...yet, but there are a few...go forward 50 years and see
What element has one main energy level?
Helium has two electrons which completely fills the first principal quantum level.
How many electrons are in the very first energy level?
there are two electrons in the first energy level of every element except for hydrogen which only has one electron in the first energy level.
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 element has only one energy level and is part of an essential liquid?
Hydrogen because it has one electron in one energy level and is needed to make water (essential liquid).
What is the maxium number of electrons an element can have on the first inner level?
The maximum number of electrons that can be found in the first energy level (or inner level) of an element is 2 electrons. This is because the first energy level only has one subshell, which can accommodate a maximum of 2 electrons.
Can an element have more than one ionization energy?
yes it can depending on the level of ionizing radiation
What element has a third energy level?
All of them.
How is the element's period related to the number of energy levels over which its electrons are spread?
The element's period indicates the number of energy levels or electron shells that its electrons occupy. Each period corresponds to a new energy level being filled by electrons. Moving from left to right across a period, the number of energy levels increases by one as you go from one element to the next.
Which element has 2 energy levels with 5 electrons in my order energy level?
This element is likely phosphorus (P), which has 15 electrons in total. With 5 electrons in the second energy level, phosphorus has 2 energy levels: the first energy level with 2 electrons and the second energy level with 5 electrons.
He highest level of occupied energy in element?
