How do you find the number of electrons on each level in an element?

This is a somewhat difficult question to answer without a picture but for the left (first) two columns of the Periodic Table (S Block) and the right (last) six columns (P block) the number of energy levels is the row number of where that atom is on a periodic table (these blocks together are known as the representative elements). For the middle part (transition elements, or D block) the number of energy levels is equal to the row number the element is in, minus one. So for example, Lithium (Li) has two energy levels. In another example, Iron (Fe) has three energy levels. For the inner-transition elements (a.k.a. the lanthanide and actinide, or F block) the number of energy levels is the row number (Lan - row 6, Act - row 7), minus two. So in example, Uranium (U) has 5 energy levels).

What is the top number mean in each element?
The top number in each element means the number of protons and electrons in the atom of that element.
What shows the number of electrons in the outer energy level?
On the periodic table, for each element there is a column of 1 to 7 numbers on the right side, these numbers show the number of electrons in each shell, or layer, The bottom number is the number of electrons in the outermost layer
How many protons and electrons are in element with an atomic number?
An element's atomic number is equal to the amount of protons in that element. Each atom has a different number of protons and electrons present in their make-up.
What is the atomic number of an element is for?
The atomic number of an element declares its number of protons as well as the number of electrons which are identical to each other.
What is the number of protons and electrons does all atoms have?
it varies for each element.
Are the number of electrons different from every atom of every element?
Each element has a different number of electrons. All atoms of that element have the same number of electrons. The number of electrons is the same as the number of protons.
What is the top number mean in each element?
The top number in each element means the number of protons and electrons in the atom of that element.
What shows the number of electrons in the outer energy level?
On the periodic table, for each element there is a column of 1 to 7 numbers on the right side, these numbers show the number of electrons in each shell, or layer, The bottom number is the number of electrons in the outermost layer
How many electrons does each element need to be stable on its outside level?
eight
How many protons and electrons are in element with an atomic number?
An element's atomic number is equal to the amount of protons in that element. Each atom has a different number of protons and electrons present in their make-up.
What is the atomic number of an element is for?
The atomic number of an element declares its number of protons as well as the number of electrons which are identical to each other.
Does each element have its own type of atom?
no Yes, the number of protons and electrons is different for each chemical element and the number of neutrons is different for each isotope.
What is the name for each atom of an element with a certain number of electrons?
photon
What is the number of protons and electrons does all atoms have?
it varies for each element.
What two parts of a atom have the same number in each element?
For every element, the number of protons, electrons, and atomic number are the same.
What is the number of electrons an atom would gain or loose when forming ionic bonds?
The number of electrons is specific for each element.
What does an atomic number tells you?
The atomic number tells you the number of protons in the nucleus. As such, it defines the element, since each element has a definite and defined number of protons. In the element, it also tells you the number of electrons, since the element (not the ion) has a neutral charge and protons = electrons.
