Magnesium
You can find out the symbol, name, mass, state, protons, neutrons, electrons, electronegativity, valence electrons, charge, and many other characteristics of the element considering the characteristics of other elements in the same group or period.
Kr has the atomic number of 36. It has similar number of electrons and protons.
You can find out the symbol, name, mass, state, protons, neutrons, electrons, electronegativity, valence electrons, charge, and many other characteristics of the element considering the characteristics of other elements in the same group or period.
Electrons in the outermost shell are valence electrons!
Gallium
The isotope of oxygen, 8O17
Protons are protons, no matter what element they are in.
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
From the element name go to the periodic table and look for the atomic number. This is equal to the number of protons and to keep the atom neutral is also equal to the number of electrons.
116 protons and electrons Number of neutrons = Atomic mass of an isotope - Atomic number of the element; Uuq has many isotopes, each with a different number of neutrons.
The number of protons in its nucleus, the number of electrons it has and its name.
an element which is then broken down into: protons, neutrons, and electrons. for a list of elements see a periodic table
