What is germanium classified?
Germanium is a chemical element with symbol Ge and atomic number 32. Classified as a metalloid, Germanium is a solid at room temperature.
What is group 4A on the periodic table?
Group 4A (or IVA) of the periodic table includes the nonmetal carbon (C), the metalloids silicon (Si) and germanium (Ge), the metals tin (Sn) and lead (Pb), and the yet-unnamed artificially-produced element ununquadium (Uuq).
What element is in period 4 Group 4?
Group 4 is the second group of transition metals in the periodic table. It contains the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). The group is also called the titanium group or titanium family after its lightest member….Group 4 element.

Why does boiling point increase down Group 4?
In Group 4 the elements change from non-metallic in character at the top of the Group to metallic at the bottom. The change in bonding from covalent to metallic down the Group causes a decrease in melting point and boiling point.
Which period 4 element has the most metallic?
Answer Expert Verified. The answer is (4) Sc. The metallic properties has the rule that from left to right, the metallic property is from high to low.
What is the least metallic element?
Chlorine is right below fluorine, making it the element with the fifth highest metallic character. This leaves fluorine as the last element, meaning it has the lowest metallic character.
Which is the most non metallic?
The most non metallic element is fluorine.
Which is the most non-metallic family?
Halogen family
What is the most metallic?
francium
Which is the most metallic family?
The alkali metals in group 1 are the most active metals, and cesium is the last element in the group for which we have experimental data.
Which is more metallic Ca or RB?
As calcium (Ca) is a group 2A element and rubidium (Rb) is a group 1A element. Hence, Rb being an alkali metal is more metallic in nature than calcium (alkaline earth metal).
Which is more metallic aluminum or thallium?
Aluminium, indium and thallium are the members of the boron family. Thallium is the biggest in size among all so we can conclude that it has the highest metallic character.
Does metallic character decreases down a group?
Metallic character refers to the level of reactivity of a metal. Non-metallic character relates to the tendency to accept electrons during chemical reactions. Metallic tendency increases going down a group. Non-metallic tendency increases going from left to right across the periodic table.
Does atomic radius decreases down a group?
In general, atomic radius decreases across a period and increases down a group. Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius.
Which element in Group 2 is the most metallic in character?
radium
Why do metallic character increases down the group?
As we move down the group, the number of shells increases. The effective nuclear charge experienced by valence electrons decreases because the outermost electrons move farther away from the nucleus. By losing the electrons, element gains positive charge. Hence, metallic character increases down the group.
What are the 5 metallic properties?
Properties of metals
- high melting points.
- good conductors of electricity.
- good conductors of heat.
- high density.
- malleable.
- ductile.
What is the order of the metallic character down the group?
Hence the correct order is, P
