The first group elements have 1 dot on their electron dot diagram, the group 2 elements have 2, group 3-12 elements have 2 electrons (with exceptions), group 13: 3 electrons, group 14: 4 electrons, group 15: 5 electrons, group 16: 6 electrons, group 17: 7 electrons, and group 18: 8 electrons.
For the groups 1, 2 13-18 the number of valence electrons is
Group 1, 1
Group 2 ,2
Group 13 ,3
Group 14, 4
Group 15, 5
Group 16, 6
Group 17, 7
Group 18, 8 (exception helium with 2)
The other elements the d block (transition metals), f block (lanthanides and actinides) the counting of valence electrons is not useful as the numbers of electrons in the outer shell does not relate in a simple way to the valency.
theses are not called colmns but are called groups of periodic table.the relation between them is that in the periodic table the elements are placed in such a way that the the number of electrons in the outermost shell are equal to the group number.
They have the same number of valence electrons (electrons in their outermost shell). They do not have the same number of shells however.
They all react
No relationship
A period are the rows going across on a periodic table, a group is the rows going up and down. there is no relation in them.
theses are not called colmns but are called groups of periodic table.the relation between them is that in the periodic table the elements are placed in such a way that the the number of electrons in the outermost shell are equal to the group number.
An element's electron configuration determines its location (group) in the periodic table. It tells us how many valence electrons (s and p sublevel).
They have the same number of valence electrons (electrons in their outermost shell). They do not have the same number of shells however.
The position in the periodic table can range in size moving from left to right, and it has a wider range of numbers, but in the outermost suborbital, it can only range from 1-8 valence electrons!
The relationship between electrons and life is the tiny subparticles react with the nuetrons creating a friction that keep are basic genomes going.
A chemical bond is an energy relationship between outer electrons and neighboring atoms.
The attraction between the atomic nucleus and electrons is less strong.
The general location of electrons in a covalent bond is that electrons are shared in pairs between 2 atoms. If 2 electrons pairs are shared, 4 electrons are shared in all.
The relationship between a cathode and an anode involves
no
Yes
They all react
