Q. What are the general properties of the elements in the group to the right in the modern periodic table?
Summary of Periodic Table Properties of Elements
- Atomic Radius Decreases.
- Ionization Energy Increases.
- Electron Affinity Generally Increases (except Noble Gas Electron Affinity Near Zero)
- Electronegativity Increases.
Q. What are the two properties of elements?
These properties include color, density, melting point, boiling point, and thermal and electrical conductivity. While some of these properties are due chiefly to the electronic structure of the element, others are more closely related to properties of the nucleus, e.g., mass number.

Q. What do the elements of Group II 2 have in common?
Answer. The property that is common to all group 2 elements is that they tend to form ionic bonds by losing electrons making these atoms positive charge. They are called cations. These elements are beryllium, magnesium, calcium, strontium, and radium.
Q. Which element of Group II is similar to Alive?
Calcium is the 20th element in the periodic table. It is a group 2 metal, also known as an alkaline-earth metal, and no populated d-orbital electrons….All living organisms (in fact, even dead ones) have and need calcium for survival.
- Calcium Hydroxide.
- Calcium Sulfate.
- Calcium Sulfide.
Q. Which group has least metallic character?
If we look at the periodic table group 17 and group 18 have the least or lowest metallic character. Now if we analyze the trends in the periodic table metallic character decreases as you move from left to right and from bottom to top of the periodic table.
Q. Which out of the following is least metallic?
The metallic character of the elements increases down the group. All given elements are of group IIA and Be is top most in that group. Thus Be has least metallic character.
Q. How does metallic character change in a group?
Metallic character is essentially how easily an atom gives away an electron to become a cation (which metals do). Going down a group, the atomic radius increases as well. Therefore, going down a group, since less energy is required to remove an electron, it becomes “easier”, and the metallic character increases.
Q. What happens in the metallic character when one moves from A to G?
Metallic character decreases as you move across a period in the periodic table from left to right. This occurs as atoms more readily accept electrons to fill a valence shell than lose them to remove the unfilled shell. Metallic character increases as you move down an element group in the periodic table.
