What is the difference of number of valence electrons and periodic table group number?
Valence electrons and group number for metal are same. For non-metals, valence electrons are equal to group number-10.
What do you notice in the number of valence electrons of metal?
The ability of an atom to loss this number of electrons.
What do you notice about the number of valence electrons as you move from left to right across a row or period?
The number of valence electrons increases from left to right across a period.
Why do group one elements have similar properties?
;need the same number of electrons to fill their valece shells ;have the same number of valence electrons
What do you notice about the number of electrons in each valence shell of noble gases?
All the noble gases have 8 electrons in their valence shell except helium which have 2 electrons in its valence shell.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
What is the difference of number of valence electrons and periodic table group number?
Valence electrons and group number for metal are same. For non-metals, valence electrons are equal to group number-10.
What do you notice in the number of valence electrons of metal?
The ability of an atom to loss this number of electrons.
What do you notice about location of these elements?
They have the same number of valence electrons
What is the number of valence electrons for Alkali Earth Metals?
Alkali Earth metals have a single valence electron, and are found in the first group.
How many valence electrons are in aluminum?
Alkaline earth metals are group 2 elements and have 2 valence electrons.
What do you notice about the number of valence electrons as you move from left to right across a row or period?
The number of valence electrons increases from left to right across a period.

What do you notice about the number of electrons in each valence shell of noble gases?
All the noble gases have 8 electrons in their valence shell except helium which have 2 electrons in its valence shell.
What is the number of valence electrons in strontium?
Strontium has 2 valence electrons because it is part of the Alkaline Earth Metals or Group 2 of the periodic table which all have 2 valence electrons
How many valence electrons do the elements of alkali metals have?
Valence electrons are the electrons present in the outermost shell of an atom.You can easily determine the number of valence electrons an atom can have by looking at its Group in the periodic table.For example, atoms in Groups 1 and 2 have 1 and 2 valence electrons, respectively.Atoms in Groups 13 and 18 have 3 and 8 valence electrons, respectively.
How does group number tell you the aout of valence electrons?
The group number tells you how many valence electrons there are, except for transition metals, lanthanides, and actinides. So, for groups 1 and 2 , there are 1 and 2 valence electrons, respectively. Then it gets a little tricky. You skip to group 13, past the transition metals. What to do? You can't have 13 valence electrons. What you do is you use only the ones digit. Thus, metals in group 13 would have 3 valence electrons. The reason that the group number tells you the number of electrons is that that is the way that Dmitri Mendeleev ( the founder of the periodic table) set it up. Good Luck!
