The atomic number of the element is the number of protons, therefore there has to be the same amount of electrons to protons.
To find the total number of electrons in an element, first you need to look up the element's atomic number. That number tells you how many protons are in the element. Then, look up the net charge of the element. The number of protons subtracted by the elements net charge will give you the number of its electrons.
Kr has the atomic number of 36. It has similar number of electrons and protons.
It is the same as the number of protons if it is a neutral atom, or the number of protons plus the charge of the ion. The number of protons is the atomic number of the element.
In a neutral atom, the number of electrons equals the number of protons. The number of protons is the atomic number of the element on the periodic table.
In a neutral atom the number of electrons is the same as the atomic number, which is the number of protons in the nucleus.
To find out the number of electrons in an element you must add the protons and neutrons and subtract that number with the atomic mass, this will determine the amount of electrons because the unknown element could be an isotope and have more than the normal amount of electrons of the non isotope element.
The number of electrons in an atom is equal to its atomic number, which is the number of protons in its nucleus. This is because atoms are electrically neutral, so they have an equal number of protons and electrons. You can find the atomic number of an element on the periodic table.
A neutral atom has the same number of electrons as it does protons. The atomic numbers on the periodic table for each element are the number of protons. So, look up the element on the periodic table, note its atomic number, and you will then know the number of protons and electrons in a neutral atom of that element. For example, magnesium (Mg) has atomic number 12. So a neutral Mg atom would have 12 protons and 12 electrons.
valence electrons is the same as the number as the last digit in the group :)
The number of protons in an atom is equal to the atomic number of the element, which can be found on the periodic table. Since atoms are electrically neutral, the number of electrons in a neutral atom is also equal to the number of protons.
you look at either the atomic number or the number of electrons. That's the number of protons.
Silver-107 has 47 protons and 47 electrons. This is because the number of protons equals the element's atomic number, and in a neutral atom, the number of electrons also matches the number of protons.
