A nuclide is a species of an atom with a specific number of protons and neutrons in the nucleus for example carbon-13 with 6 protons and 7 neutrons. When 226 Ra emits an α particle 4 He two protons and two neutrons are carried away Fig. Atom Energy Education The smallest possible amount of matter which still retains its identity as a chemical element consisting of a nucleus surrounded by electrons. . The product of radium α decay the daughter is a different element. The role of the element in humans animals and plants. We accept only Visa MasterCard American Express and Discover for online orders. Therefore the residual nucleus has 86 protons and 136 neutrons. The description of the element in its natural form. Hydrogen for example has one proton and one electron with no neutrons. For example the radium nucleus Z 88 A 226 has 88 protons and 138 neutrons. Neutrons are uncharged particles found within the nu...

Indeed the most stable valency for all the elements is three. Why does scandium have 9 electrons in the third shell. Transition Metals 288 right it readily accepts the electron given by the sodium atom. . Most have two with several notable exceptions. The total number of valence electrons is 5611. Valence electrons in Fluorine F 7. The answer is b boron aluminum has 3 valence electrons magnesium has 2 boron has 3 silicon has 6 scandium and vanadium are both transition metals with 2s4 and 9 and 11 n 3 electrons. An atom consisting of a closed shell of valence electrons will usually be chemically inert. Most transition metals have 2 valence electrons. Atoms of group 18 elements have eight valence. 3 question In general how many valence electrons do transition metals have. Therefore the valence electrons of cobalt Co are nine. Elements in the d block are transition elements and each posses on...
