How many electrons are in the highest occupied energy level of the sodium?
Sodium: Na(2, 8, 1 ) so there is one electron in the highest (3rd) level
How many orbitals are in second energy level?
There are two sublevels in the second principle energy level. The s sublevel has one orbital and the p sublevel has 3, for a total of 4 orbitals.
How is solar energy transported from one place to another?
Solar energy is transported through food chains/webs in ecosystems, as part of an energy pyramid, which has 3 main trophic levels: * Level 1: Autotrophs (plants) fix the energy from the sun during photosynthesis; the energy becomes part of the plant biomass * Level 2: Herbivores consume the plants * Level 3: Primary carnivores feed on herbivores, and are consumed by: * ** Secondary carnivores At each level the energy consumed is assimilated and then either respired, or becomes part of the biomass. Some species participate at more than one trophic level, for instance birds which are herbivores and carnivores. Ecosystems are not very efficient at capturing solar energy; plants capture only 1% of the energy available from sunlight, and far less than that eventually reaches the top of the pyramid.
What the number of energy levels of hydrogen?
energy level 1=__1__ energy level 2=__4__ energy level 3=__9__ 1 2 3 Edit: The question is clear L,--> Orbital # 1...0 2...0,1 3...0,1,2
How many outer levels does Cesium have?
One electron in outermost energy level.
What element has one energy level?
hydrogen
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.
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 element has atoms with only one completely filled principal energy level?
undiscovered...yet, but there are a few...go forward 50 years and see
Can an element have more than one ionization energy?
yes it can depending on the level of ionizing radiation
When an atom of one element combines chemically with an atom of another element both atoms usually attain the stable highest energy level configuration of a?
molecule
What element is a noble gas in the first energy level?
There are no noble gases in the first energy level. Noble gases are found in the last (highest) energy level of an atom. The first energy level can only hold a maximum of 2 electrons, while the noble gases have completely filled outermost energy levels.
How many electrons are in the second energy level of an element?
8. level one has 2 level two has 8 level three has 18 level four has 32 level five has 50 level six has 72
Why the positions of the dark bands on the absorption spectrum for an element correspond to the bright bands on the emission spectrum of the same element?
It requires a certain amount of energy to raise an electron from a specific level to another specific level; the same amount of energy is released again if it falls back down. One - the electron moving up an energy level - corresponds to the absorption of energy; the other - the electron falling down - corresponds to the emission of energy.
What type of energy is released when one element decays into other element?
kinetic energy
Which element has 19 protons and 1 valence electron?
Potassium has 19 total electrons and one electron in its 4th energy level.
Is riboflavin an element?
There is only one main element in riboflavin. This main element in riboflavin is known as B12 and is water soluble.
