How many valence electrons do transition elements have?
Halogen family members, or elements in group 17, have 7 valence electrons.
The elements in 3A all have 3 valence electrons.
There are 7 valence electrons in elements of group-17. They are called halogens.
The alkali earth elements have TWO valence electrons.
That depends on the element in question. Atoms can have anywhere from 1 to 8 valence electrons. For the main group elements, Groups 1,2,13-18, the number of valence electrons are the number in the one's place in their group number, as follows: Group 1 Elements: 1 valence electron Group 2 Elements: 2 valence electrons Group 13 Elements: 3 valence electrons Group 14 Elements: 4 valence electrons Group 15 Elements: 5 valence electrons Group 16 Elements: 6 valence electrons Group 17 Elements: 7 valence electrons Group 18 Elements: 8 valence electrons The transition metals, Groups 3 - 12, are more complicated because they are adding d electrons, some of which behave like valence electrons, and many transition metals can have different numbers of valence electrons. For example manganese can have anywhere from 2 to 7 valence electrons.
Gold has 25 valence electrons
there are 36 electrons in a valence shell. -cmoney
2 valence electrons are in iridium because iridium is a transition metal. Most transitions metal would have 2 valence electrons because the group before the transition metals are the alkaline-earth metals which contains 2 valence electrons in that group making the transition metals have 2 valence electrons.
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
Elements in group 8 all have 8 valence electrons, this is why these elements are in group 8, they are called noble gases, some examples are Argon, Xenon,
Group 16 (VIB or VIA) elements have six valence electrons.
Group 16 (VIB or VIA) elements have six valence electrons.
