What else can I help you with?
Is Strontium oxide acidic or basic?
Strongly basic.As the size of 2+ cations increase down the alkaline group basicity increases.
Why boiling point of noble gases increase down in the group?
The melting and boiling points increase down the group because of thevan der Waals forces. The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.
Does the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
What is the trend in density as you go down the group of halogens?
The density increase down.
Does a nonmetallic character increase or decrease down a group?
Down a group, the number of shells increases, also the atomic size. Thus , the metallic character increase does increase as going DOWN a group. It is easy to remove an electron froman atom of bigger size.

How does the reactivity of group 1 metals change as you go down group 1?
The reactivity increase down in the group.

The reactivity is increasing goinng down in the group.
What is the Group trend Atomic radius?
The group trend for atomic radius is that it tends to increase down a group in the periodic table. This is because as you move down a group, the number of electron shells increases, leading to a larger atomic radius. Additionally, the effective nuclear charge decreases down a group, which also contributes to the increase in atomic radius.
What is the trend in density as you go down the group of halogens?
The density increase down.
Does shielding increase as you move down a group in the periodic table?
Yes, shielding increases as you move down a group in the periodic table.
Does a nonmetallic character increase or decrease down a group?
Down a group, the number of shells increases, also the atomic size. Thus , the metallic character increase does increase as going DOWN a group. It is easy to remove an electron froman atom of bigger size.
What is the trend in atomic mass going down a group?
The atomic mass will increase. As you go down a group in the periodic table the atomic number rises, this increase in the number of protons is accompanied by an increase in the number of neutrons to stabilise the nucleus, and both together lead to an increase in atomic mass.
Why do elements increase in size as you move down the periodic table?
Down the group, atomic radius increases. This is due to increase in number of shells.
What are the acidity and basicity trends of the periodic table?
The acidity and basicity trends on the periodic table are primarily based on the atomic size and electronegativity of elements. Generally, as you move from left to right across a period, elements become more acidic due to increasing electronegativity pulling electron density towards the nucleus, making it easier to donate a proton. Conversely, as you move down a group, elements become more basic due to larger atomic size and higher electron shielding, allowing for easier acceptance of a proton. However, there are exceptions to these trends based on specific chemical properties and bonding characteristics of elements.
What does an increase of 1 pH number represent?
10x increase in acidity
