Which elements has the largest atomic radii in periodic table?
The atomic radii of members of the Group 1A (Alkali metals), increases down the group. Therefore Francium has the largest atomic radius of the Alkali metals. However Fr has no stable isotopes, thus is not naturally occurring. So Cs-133 is the largest you can find.
Why melting point decrease down the group for Alkali metals but increase for Halogens?
Because the atomic radius increases down the group 1 and decreases down the group of halogen
Which element has a larger atomic radius strontium or magnesium?
Strontium: At least within periodic table columns that do not include transition metals, an element with higher atomic number always has a larger atomic radius. This principle is generally correct also for columns that do include transition metals, but in an important exception, hafnium has almost the same atomic radius as zirconium, making the separation of these two metals very difficult by chemical means.
What does the horizontal placing of the elements in the periodic table signify?
It signify the group of the element. For example, the first group is called alkali metals. When it is moving from left to right of the periodic table, the atomic radius decreases, the ionization energy increases, and the electronegativity increases.
What happens to the atomic radius as you go down the metals What happens to the reactivity?
Examples for the groups I an II of the periodic table:- the atomic radius grows from top to bottom- the electronegativity descends from top to bottom
What is the biggest element in the alkali family?
Francium has the biggest atomic weight and the biggest atomic radius between the alkali metals.
Which elements has the largest atomic radii in periodic table?
The atomic radii of members of the Group 1A (Alkali metals), increases down the group. Therefore Francium has the largest atomic radius of the Alkali metals. However Fr has no stable isotopes, thus is not naturally occurring. So Cs-133 is the largest you can find.
What group of elements have members of the smallest atomic radii for a given period?
Noble gases have the smallest atomic radius.
What is the larger element in the alkali metal family?
Francium has the most larger atomic weight and also the largest atomic radius between the alkali metals.
How do sizes of atoms of alkali metals compared to their positive ions?
The atomic radius of cations is lower.
Which alkali earth metal has the smallest atomic radius?
The alkali earth metal with the smallest atomic radius would be beryllium(Be), number four
Which elements on the periodic table have the lowest electronegativity?
Atoms to the left on the periodic table Atoms with a large atomic radius
How does the ionic radius of a nonmetal compare with its atomic radius?
in the case of non-metals, the anions are formed by the addition of electrons. So the ionic radius is larger than that of the atomic radius
Why melting point decrease down the group for Alkali metals but increase for Halogens?
Because the atomic radius increases down the group 1 and decreases down the group of halogen
Which of the following decrease as you go from left to right on the periodic table?
The atomic radius decreases as you go from left to right. or atomic radius cation radius && anion radius -barbie=]
The alkaline earth element having the largest atomic radius is found in period?
7th period because atomic size down the group increases. And Alkali Earth metals are found only in Group 1. The element is in Group 1 and period 7
Why is there a pattern between the atomic radius and melting points within alkaline earth metals or period 2 metals?
