What families are included in the s block periodic table?
Group 1A and 2A, or Alkali metal and Alkaline earth metal.
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.
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 is group 2 in the periodic table?
Alkaline-earth metals
What group is barium in in the periodic table?
Group: Second groupThat means its family is alkaline earth metals.
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?
group 7A the halogens.
How many electrons do the elements in Group11A2 of the periodic table have in their electron dot diagrams?
they have 2
What families are included in the s block periodic table?
Group 1A and 2A, or Alkali metal and Alkaline earth metal.
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.
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.
What describes the alkaline metals?
The alkaline metals group is the group at the very left group on the periodic table. The elements in this group have only 1 electron in the outer shell, so they react very easily, with for instance water.
Why are Alkaline metals not found free in nature?
because they are extremely reactive. They belongs to group of one periodic table and have one electron in the outer valence shell.
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
Why are the alkaline earth metals less reactive hen the alkali metals?
The alkaline earth metals are in group 2 of the periodic table this means they have 2 electrons in each of their outermost energy 'shells'. The alkaline metals are in group 1 and only have 1 electron to lose in a reaction rather than 2. This means the alkaline metals react more readily.
What element is not an alkiline metarlanad is at the top of the peroopdoc tabel?
Hydrogen is the element which is not alkaline metal but in the top of the periodic table. It is depicted in the 1st group because it has 1 valence electron. It is a non metal.
Is an alkaline earth metal an element in groups 3-12 of the periodic table?
The alkaline earth metals are beryllium, magnesium, calcium, strontium, barium, and radium.
