In the Periodic Table, group A refers to the main groups, including the alkaline metals (group 1) and the oxygen family (group 16). The electron dot diagrams for the alkaline metals would contain one dot, as they have one valence electron. In contrast, the oxygen family elements have six valence electrons, resulting in their electron dot diagrams containing six dots. Therefore, the diagrams for the oxygen family would contain more dots than those for the alkaline metals.

What families are included in the s block periodic table?
Group 1A and 2A, or Alkali metal and Alkaline earth metal.
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
How many valence electrons alkali metals have?
alkali metals have 1 electron in there outer valence shell. I remember that alkali and alkaline go with columns 1 & 2 of the periodic table alphabetically. Alkali then alkaline. Alkali metals have 1 valence electron. Alkaline metals have 2 valence electrons.
What row is calcium in?
Calcium is located in the 4th row (or period) of the periodic table. It is a member of the alkaline earth metals, found in Group 2. This means it has four electron shells, with the electron configuration of [Ar] 4s².
Which group will have an electron configuration that ends in s2?
Elements in Group 2 of the periodic table will have an electron configuration that ends in s2. This group includes elements such as beryllium, magnesium, and calcium. They have two electrons in their outermost s sublevel.
In a periodic table that included electron dot diagrams in which column would the diagrams contain more dots Group 3A the boron family or Group 7A the halogens?
In Group 3A (boron family), the electron dot diagrams would contain more dots as these elements typically have 3 valence electrons. In Group 7A (halogens), the electron dot diagrams would only have 1 dot as halogens have 7 valence electrons.
How many electrons do the elements in Group11A2 of the periodic table have in their electron dot diagrams?
Elements in Group 11 (coinage metals) of the periodic table, such as copper, silver, and gold, have 1 electron in their outer shell. This results in electron dot diagrams where they have one dot represented around the element's chemical symbol.
What families are included in the s block periodic table?
Group 1A and 2A, or Alkali metal and Alkaline earth metal.
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
What type of element loses an electron to become an ion?
Alkaline metals and hydrogen, all the elements in the first column of the Periodic Table.
How many valence electrons alkali metals have?
alkali metals have 1 electron in there outer valence shell. I remember that alkali and alkaline go with columns 1 & 2 of the periodic table alphabetically. Alkali then alkaline. Alkali metals have 1 valence electron. Alkaline metals have 2 valence electrons.
Which element is a metal with an outermost electron configuration of 6s2?
The element with an outermost electron configuration of 6s2 is Barium (Ba). It is classified as an alkaline earth metal on the periodic table.
Look at the periodic table. What is the charge on any ion formed by an alkaline earth metal?
The charge on any ion formed by an alkaline earth metal is typically +2. This is because alkaline earth metals readily lose two electrons to achieve a full outer electron shell and acquire a stable electron configuration.
How can one draw electron dot diagrams effectively?
To draw electron dot diagrams effectively, start by determining the number of valence electrons for the element. Then, place one dot around the element symbol for each valence electron, pairing them up as needed. Remember to follow the octet rule for main group elements. Practice and familiarity with the periodic table will help improve your skills in drawing electron dot diagrams accurately.
Why isnt the mass of the electron included in the mass of an atom on the periodic table?
the mass of electron is very less compared to that of a proton or a neutron it is 1/1800 the mass of 1 proton and therefore it is negligible and not included.
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.
What row is calcium in?
Calcium is located in the 4th row (or period) of the periodic table. It is a member of the alkaline earth metals, found in Group 2. This means it has four electron shells, with the electron configuration of [Ar] 4s².
