How many electrons do the elements in group IA of the periodic table have in their electron dot diagrams?

This is different for each period of group IIA in the P.T.
Examples:
Be in period 2 has 4 electrons, Ca in p.4 has 20and Ra in p.7 (down under in P.T.) has 88 electrons.
The whole row: 4, 12, 20, 38, 56, 88 electrons, from top to bottom in group IIA

Does group 2 on the periodic table gain or lose electrons?
they will lose electron to form mono positive cation
What is the number of valence electron for all the elements in periodic table group 2A 2?
Two valence electrons.
What is the number of valence electrons in group one?
Valence electrons are the electrons in the furthest electron shell from the nucleus.For the first three rows, essentially, the number of valence electrons is the number of squares the element is away from the beginning of the row at the left.For example. Sodium is the first (group 1) it has 1 valence electron. Magnesium is the second, it has 2 valence electrons.
What elements on the periodic table has six valence electrons?
Oxygen, with a electron number of 8 there are two electrons on the first orbit ring and six an the outer ring(shell) those are the valence electrons
Why do elements in the same group or column of the periodic table have similar properties?
Elements in the same column on the periodic table have similar chemical reactivity because they have the same outer electron configuration and it is the electron structure that determines an elements properties.
How many electrons do the elements in Group11A2 of the periodic table have in their electron dot diagrams?
they have 2
Why do sodium and potassium have the same number of dots in their electron dot diagrams?
Electron dot diagrams show the number of valence electrons and whether they are paired or unpaired. One of the trends of the periodic table is that elements within the same group have the same number of valence electrons. Sodium and potassium are in the same group.
How many completely full electron shells do the elements in the third row contain?
it should be 18 however a lot of scientists use 8 to avoid confusing diagrams
What do elements in the same group in the periodic table have in common?
They have the same number of valence electrons, or electrons in the outer electron shell. This allows them to react with certain elements.
Is the periodic table is most easily understood in terms of the electron configurations of the elements?
Yes. In terms of electron configuration and the number of valence electrons.
Does group 2 on the periodic table gain or lose electrons?
they will lose electron to form mono positive cation
What is the number of valence electron for all the elements in periodic table group 2A 2?
Two valence electrons.
What group in the periodic table gains electrons most readily and why?
Group-17 in the periodic table gains electron most readily. The elements in this group require only one electron to complete its octet.
What do the elements in the periodic table have?
Elements in the same column have the same number of valence electrons, and form ions with the same charge.
What patterns are noted in the electron structures of elements found in a periodic and in a family in the periodic table?
The period (row) indicates how many electron shells the element has and the family (column) indicates how many valence electrons the element has.
How do elements of the periodic table interact?
Listed in order of atmoic weight. Electrons have the majority of weight in the atom (proton, neutron, electron.)
What is the number of valence electrons in group one?
Valence electrons are the electrons in the furthest electron shell from the nucleus.For the first three rows, essentially, the number of valence electrons is the number of squares the element is away from the beginning of the row at the left.For example. Sodium is the first (group 1) it has 1 valence electron. Magnesium is the second, it has 2 valence electrons.
