27 protons, 33 neutrons, 27 electrons The cobalt atom has 27 protons as seen in the periodic table. There are also 27 electrons because the charge is 0. There are 33 neutrons because 60-27 = 33.

Explanation: The element cobalt is characterzied by the presence of 27 massive, positively charged particles, 27 protons , in its nucleus. Since it is 58Co , there are 31 neutrons , 31 massive, neutrally charged particles in its nucleus.

The Carbonate (CO2−3) Ion Carbon has 4 valence electrons, each oxygen has 6 valence electrons, and there are 2 more for the −2 charge. This gives 4 + (3 × 6) + 2 = 24 valence electrons.

The number of electrons each energy level can hold increases as you add more and more energy levels to an atom. and so on. In your case, cobalt, Co , is said to have a total of 27 electrons surrounding its nucleus.

Most transition metals have 2 valence electrons. Valence electrons are the sum total of all the electrons in the highest energy level (principal quantum number n). Most transition metals have an electron configuration that is ns2(n−1)d , so those ns2 electrons are the valence electrons. For example.

1 Answer. Oxygen has 6 valence electrons. A way to remember this is to note that it is in column 16 of the periodic table. For the representative elements (columns 1, 2, 13-18), the digit in the units place of the column number is the same as the number of valence electrons.

The Lewis structure for XeF4 has a total of 36 valence electrons. When we are done adding valence electrons we check each atom to see if it has an octet (full outer shell).
