Does cobalt have 1 valence electrons?
Cobalt having atomic number 27 has a total of 27 electrons in it with 1 valence electrons.
Does cobalt have 9 valence electrons?
Since there are 9 electrons after the noble gas configuration of Argon, Cobalt has 9 valence electrons.
What family has 8 valence electrons?
Noble Gases
Noble Gases The Group 18 elements are the noble gases. Atoms of the noble gases have 8 valence electrons, except for helium, which has 2.
How many valence electrons do have?
seven valence electrons
Iodine has seven valence electrons.
How do you determine the number of valence electrons?
To find the valence electrons in an atom, identify what group the element is in. An element in group 1A has 1 valence electron. For example, Li is in group 1A, so that means it has one valence electron. If the element is in group 2A , then it has two valence electrons.
What elements have valence electrons?
Valence electrons are electrons in the outmost shell (energy level). They are the electrons available for bonding. Group 1 (alkali metals) have 1 valence electron. Group 2 (alkaline earth metals) have 2 valence electrons. Group 13 elements have 3 valence electrons.
Which element has atoms with only two valence electrons?
The carbon atom is in group 14 of the periodic table of elements. It has a valence electron configuration of 2s2 2p2. This group is termed as the carbon group , and it consists lead, silicon, tin and germanium . Group one atoms have one valence electron, and group two atoms have two valence electrons.
