The highest occupied energy level of an atom?
it very easy: whatever row the element is in is the number of energy levels it has. Example: hydrogen in the first row, it has 1 energy level.Read more: How_do_you_find_number_of_energy_levels_in_an_element
Why is the ionization energy needed to remove the first two electrons from Magnesium atoms relatively low?
magnesium has a 2 valence electrons. because the third electron is not a valence electron, or in the outer shell, much more energy would be needed to remove it
What diagram shows the valence electron pattern of carbon Adams?
A diagram of a typical carbon atom would show a nucleus comprised of 6 protons and 6 neutrons. It would also have two electrons in the first energy level, then 4 electrons in the second, or valence energy level (1s22s22p2.)
What the maximum number of electron can go in the first three energy levels subatomic particles?
the first energy levels hold 2, 8, and 18 a total of 28 electrons
If the first and second energy levels of an atom are full.what would be the total number of electrons in the atom?
First energy level can hold 2 electrons.Second energy level can hold 2 + 6 = 8 electrons. Total = 10 electrons.
How many energy levels are in an electrically neutral sodium atom?
the element sodium has 1,000,000 million energy levels.

How many electrons can be in the first energy levels?
Two electrons can be housed in the first energy level.
What are atoms doing during a chemical reaction?
In an atom, there are several energy levels. However, within each energy level there are subshells. The first row of the Periodic Table (PT) has one energy level. The second row has two energy levels, and the second row has two subshells. The third row of the PT has three energy levels; the third energy level has three subshells. The outer subshell is called the valence shell, and it holds valence electrons. The first energy level can hold a maximum of two valence electrons. The second valence shell can hold 8 valence electrons. The third valence shell can hold 18. Past four the numbers get big, so we will not go there. The number of electrons that fill the valence shells determines reactivity. The Alkali Metals (first column) only need to give away 1 valence electron. The Halogens (second-to-last column) only need one to fill their outer shells. Put a Halogen and an Alkali Metal together and they will violently react in order to fill their valence shells. Atoms, in a reaction, are sharing electrons with other atoms.
What are the number of valence electrons in phosphorus?
there are five valence electrons in an atom of phosphorus
How many electrons are in the third energy level of phosphorus?
Phosphorus atoms have five valence electrons. You can know this because P is in group 15/VA. The number of valence electrons is the same as the VA group number (5), or group number 15 minus 10, which is 5.
How many energy levels does carbon have?
Carbon has 2 energy levels. There are 6 electrons, 6 protons, and 6 neutrons.
How many electrons can fit in the first four energy levels?
32 electrons can fit
Who sugessted thatthe electrons orbited the nucleus in fixed energy levels?
Niels Bohr first suggested that electrons orbited the nucleus in fixed energy levels.
What is the neutral atom that has its first two energy levels filled has 6 electrons in its third energy level and has no other electrons?
What is the neutral atom that has its first two energy levels filled, has 5 electrons in its third energy level, and has no other electrons? Enter the name of the element, not the abbreviation.
What is a valence ring?
explain the function of the" "valence ring
How many electrons are in each circle?
If you mean energy levels then the first level has 2 electrons, and the other levels contain 8 electrons for each level
