Which metals are in group 2 from top to bottom?
The metal of group 2 from top to bottom are Be, Mg, Ca, Sr, and Ba.
Which of these will form ions most readily 1 point Be Mg Ca Ba?
1 ) Barium will form ions most readily because it is most metallic and ions electrons readily and form a positive ion.
Which of these is an element of group 2?
The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
What type of ion does group 2 of the periodic table make?
2+ ions
Moving from the far left to the right on the periodic table, main-group elements tend to form cations with a charge equal to the group number. That is, group 1 elements form 1+ ions; group 2 elements form 2+ ions, and so on.
What is the name of Ba2+?
CHEBI:37136

What is the alkali metal in period 2?
Lithium is the first alkali metal in the periodic table, and the first metal of any kind in the periodic table. At standard temperature and pressure, lithium is a soft, silver-white, highly reactive metal.
Which will form ions readily?
As the atomic size increases, the nuclear charge decreases. Due to this, electrons of the outermost shell lie further away from the nucleus making the removal of electrons easy. So, Ba will form ions readily.
What group is Ca?
Group 2
calcium (Ca), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table.
What do Mg Ca and Sr have in common?
They have the same number of valence electrons. What do the elements Mg, Ca, and Sr have in common? An atom’s mass number is 210 and its atomic number is 85.
Are group 2 metals soft?
The Group 2 alkaline earth metals include Beryllium, Magnesium, Calcium, Barium, Strontium and Radium and are soft, silver metals that are less metallic in character than the Group 1 Alkali Metals. All the elements in Group 2 have two electrons in their valence shells, giving them an oxidation state of +2.
Which element is a metal that only forms 2+ ions?
The alkaline earth metals (red) always form +2 ions.
What is the atomic number of Ba 2?
56
Barium is a chemical element with the symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal….

What are the metals of Group 2 from top to bottom?
The metal of group 2 from top to bottom are Be, Mg, Ca, Sr and Ba. (1) Which one of these elements will form ions most readily and why? (2) State the common feature in the electronic configuration of all these elements.
Which of the metals of Group 2 will form ions most readily?
The metals of Group 2 from top to bottom are : Be, Mg, Ca, Sr, Ba. Which of these metals will form ions most readily and why. Barium will form ions most readily because Barium, whose chemical symbol is Ba, is one of the alkaline metals and we know that the chemical reactivity of metals increases as we move from top to bottom in a group.
Why does barium form ions most readily?
So barium will form ions most readily due to high ionisation potential. (2) All the atoms in a group have the same number of valence electrons and same valency. All these elements belong to group 2 and hence have 2 valence electrons and also valency is 2. Answer verified by Toppr
Why does a metal lose electrin more easily down the group?
Ba i.e. barium is your answer. As ons goes down the group the ionisation potential decreases and so the metal losses electrin easily. kya benstokes tumhaare liye bhi ladki dhundu xd haa@ rishabh: nahi humne to aapko nhi bola tha..
