Can you describe the general trend in atomic radius in group 2A?
In the group 2 (IUPAC name) of the periodic table the atomic radius increase from beryllium to radium.
What is the charge on an ione of group 2 element?
+ve 2
How does the atomic radius change from top to bottom in a group 1 and 2 in the periodic table?
Going down and to the left on the periodic table, atomic radius increases. Therefore, the smallest atomic radius is that of Helium (He), and the largest is that of Francium (Fr). Coincidentally, these are also the most and least reactive elements.
Does an element on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.
Why does the density of group 2 metals increase?
The density of group 2 metals increases as you go up the group. This is because atomic radius decreases as you go up the group. Density is mass / volume and the ratio of mass to volume of atoms of the elements goes up with the decrease in radius.
Do radium and radius have the same meaning?
Radium and radius do not mean the same thing. Radium is an element in group 2. It is radioactive and was discovered by the Curies. Radius is either the distance from the centre of a circle to its circumference, or a bone in the forearm.
Element M reacts with chlorine to for a compound MCl2 Element M is more reactive than magnesium and has a smaller radius than barium the element is?
Element M can be a choice of 4 elements, Beryllium, Magnesium, Calcium, or Strontium. The element must have an oxidation of +2, which means group 2 elements. The atomic radius of a barium atom is 222pm. Radium has a larger atomic radius that Barium, so that is eliminated, and Barium is the same as Barium so that is also eliminated.
What element is located in group 15 and period 2?
The element phosphorous (P) is located in group 15, period 2.
What element is found in group 14 period 2?
what element is found between period 2 and group 14
What type of bond has a combination of a group 2 element with a group 17 element?
Ionic bond.
Is magnesium a transition element?
No, Magnesium is a group 2 element.
Can you describe the general trend in atomic radius in group 2A?
In the group 2 (IUPAC name) of the periodic table the atomic radius increase from beryllium to radium.
Which element group is magnesium and calcium members of?
They are both in Group 2
How many atoms of a Group 17 element would be needed to react with one atom of a Group 2 element Explain.?
Two of them. A group 2 element has two valency electrons whereas those in group 17 have 7. The latter need one electron to make an ionic bond so two of them can react with a single group 2 element.
