How many valance electrons does oxygen have?
Oxygen has 6 valence electrons. A person can determine the number of valence electrons by looking at the periodic table. since oxygen is in the 6th column form the left, it has 6 valence electrons.
How many valence electrons does an atom of any halogen have?
A halogen is located in group 17 of the periodic table, so the electron configuration for the valance electron would be ns2np5 (n=energy level). So all halogens have 7 valance electrons.
How can you determine the number of valance electrons by looking at the periodic table?
look at the group number; an atom can only have 8 valance electrons. any thing higher than 10, subtract 10 from it and you get the valance elections. This way would not work for transition metals in group 7 and up.
How many core electrons in Ni?
28 electrons Nickel atoms have 28 electrons and the shell structure is 2.8.
How many protons do Argons have?
Argon atoms have 18 protons which is similar to the number of electrons.
How many valance electrons are in trivalent atoms?
14
How many valance electrons does samarium have?
2 valance electrons
How many valance electrons in Co?
There are 27 valance electrons.
How many valance electrons are in iodine?
Iodine has 7 valance electrons
How is the reactivity of elements related to valence electrons in atoms?
Valance electrons means that the element has not reached the octet configuration and is therefore reactive the reactivity depends on the no. of valance electrons the more valance electrons the more unstable the atom is and the more reactive it is.The gasses like helium neon xenon are all inert which means they have an octet configuration and have no delocalised or valance electrons.
How can the number of valence electrons be determined from the periodic table?
By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons
What are atoms that receive electrons and become negatively charged?
Basically the nonmetals. Many of them receive electrons, like oxygen, nitrogen, selenium, tellurium, and many others.
How many elements within a row different?
They have different numbers of valance electrons
How many valance electrons does selenium have?
6 valence electrons
How many valance electrons oxygen have?
6 valence electrons
How many additional valance electrons does fluorine need to have a valance shell?
1
How many atoms are in the valance shell of 17 protons?
7. there is 17 electrons, 2 in the first shell, 8 in the second and 7 in the third
