Among the elements listed—calcium (Ca), magnesium (Mg), beryllium (Be), and strontium (Sr)—beryllium (Be) is the smallest in terms of atomic size. This is because beryllium is higher up in the Periodic Table, with fewer electron shells compared to the other elements, resulting in a smaller atomic radius.
What else can I help you with?
How many elements have two valence electrons?
Examples: Ca, Mg, Ba, Sr, Ra, etc.
Which is smallest Be Mg Sr Ca?
Among the elements Be (beryllium), Mg (magnesium), Sr (strontium), and Ca (calcium), beryllium (Be) is the smallest in terms of atomic size. This is because atomic size increases down a group in the periodic table due to the addition of electron shells. Since beryllium is at the top of Group 2, it has the least number of electron shells and therefore a smaller atomic radius compared to magnesium, calcium, and strontium.
Rank the following elements in order of increasing first ionization energy C Ne Sr Mg Be?
Ne (Highest First Ionization Energy) C Be Mg Sr (Lowest First Ionization Energy)
Which was does not react with cold water Ca or Mg or Sr or Ba?
Mg does not react with cold water while Ca, Sr, and Ba react with cold water to form metal hydroxide and hydrogen gas.
Metals having only two electrons in the highest energy level?
Group 2 metals (Be, Mg, Ca, Sr, Ba, Rn) have two electrons in their valence shell.
Which of the following elements has the lowest electronegativity ba ca mg sr?
Mg (magnesium) has the lowest electronegativity among Ba, Ca, Mg, and Sr.
Which elements are in the same family as magnesium and what type of elements are they?
Be,Ca,Sr,Ba are in the same group as Mg. They all are metals
How many elements have two valence electrons?
Examples: Ca, Mg, Ba, Sr, Ra, etc.
Which element is an alkaline earth?
All the elements of Group 2 (Be, Mg, Ca, Sr, Ba, Ra)
Which is smallest Be Mg Sr Ca?
Among the elements Be (beryllium), Mg (magnesium), Sr (strontium), and Ca (calcium), beryllium (Be) is the smallest in terms of atomic size. This is because atomic size increases down a group in the periodic table due to the addition of electron shells. Since beryllium is at the top of Group 2, it has the least number of electron shells and therefore a smaller atomic radius compared to magnesium, calcium, and strontium.

What do the elements Mg Ca Sr have in common in the periodic table?
Mg, Ca, and Sr all belong to Group 2 of the periodic table, known as the alkaline earth metals. They have similar chemical properties due to their outer electron configuration with 2 valence electrons. They are all reactive metals that can form 2+ cations.
Which was does not react with cold water Ca or Mg or Sr or Ba?
Mg does not react with cold water while Ca, Sr, and Ba react with cold water to form metal hydroxide and hydrogen gas.
What metals are in the alkaline earth group?
Be, Mg, Ca, Sr, Ba, Ra
What group of elements is alkaline earth metals?
Alkaline earth metals are found in Group 2
What family does mg belong to?
Be, Mg, Ca, Sr, Ba, and Ra all belong to the family Alkaline Earth Metals
How many elements are in group 2A?
There are six elements in group 2A A group is a vertical column. The group consists of Be , Mg, Ca ,Sr, Ba , and Ra.
