how many valence electrons does a conductor such as copper have?

Most commonly used electrical conducting material is aluminium and it has three valence electrons, and another metallic conductor is magnesium which has two valence electrons. The most popularly known electrical conductor is copper, and the copper atom has only one valence electron.

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.

There are 2 's'-type electrons on cobalt's outermost, or valence, shell. But because cobalt's a transition metal, the 7 'd'-type electrons can count as valence electrons, though they rarely react with anything. There's 2 or 9 valence electrons, depending on context.

Oxygen, for example, has six electrons in its valence shell. Neither donating nor accepting the valence shell electrons of the other will result in the oxygen atoms completing their valence shells. Two atoms of the same element always form covalent bonds.

Like many of the transition elements, copper has a colored ion. Copper typically forms a bluish green solution. Copper (Cu) has two valences Cu I (cuprous) has one valence electron and Cu II (cupric) has two valence electrons.

Metals have low ionization energy. Therefore, the valence electrons can be delocalized throughout the metals. Delocalized electrons are not associated with a particular nucleus of a metal, instead, they are free to move throughout the whole crystalline structure forming a "sea" of electrons.

Now, magnesium, Mg , has 2 valence electrons. In order to complete its octet, it must get to 8 valence electrons. The only way for magnesium to accomplish this is to give up its two valence electrons and have one of its filled energy levels become the valence shell, i.e. the outermost energy level.

The conductivity of the atom depends on the number of electrons that are in the valence shell. When an atom has only one electron in valence shell, it is almost a perfect conductor. When an atom has eight valence electrons the valence shell is said to be complete and the atom is an insulator.

The outer energy level for this atom is n = 3, and it has two electrons in this energy level. Therefore, magnesium has two valence electrons.

The noble gases are the only non-transition-metal elements that have eight valence electrons in their neutral, ground state configuration, but atoms of other elements can produce a full octet -- an outer shell with eight electrons -- by gaining or losing electrons.

Metals have one to three electrons in their outer shell, whereas non-metals have four to eight electrons. Another difference is that metals tend to lose their valence electrons, but non-metals share or gain valence electrons. ... While metals are good conductors of electricity and heat, non-metals are poor conductors.

It has 2 valence electrons. The element is calcium, a metal.

Any element in group 18 has eight valence electrons (except for helium, which has a total of just two electrons). Examples include neon (Ne), argon (Ar), and krypton (Kr). Oxygen, like all the other elements in group 16, has six valence electrons.

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.
