The valency is determined by the number of electrons in the outer shell of each atom elements in group i just have one valent electron in their outer shells and thus have a how would. Determine the number of protons, neutrons, and electrons in an atom.
An atom contains equal numbers of protons and electrons.
Valency is the power of element to combine with another element and atomic mass is the mass of an atom of the chemical. The atomic number of sodium is 11 (z=11). Find the number of protons, electrons and neutrons in it. How to find a electron configuration for copper | dynamic periodic table of elements and chemistry this video is about the easy learning of atomic number, atomic mass, valency and electronic configuration. Atoms contain protons, neutrons and electrons. These elements show variable valency due to less difference in atomic size. Combinations of elements are made on the basis of their combining capacities called valencies. Since protons and electrons have equal and opposite charges, this means that atoms are have no overall electrical charge. Therefore, valence electron in sodium is 1 and it needs to lose 1 electron from the. Atoms of different elements usually have different mass numbers, but they can be the same. 2, 8, 1 electrons are distributed in the shells k, l, m respectively.
