Tin is metallic because the shielding of electrons is so much that the electrostatic force is weak and so Tin is metallic. Moreover as we move from right to left in a Periodic Table and top to bottom along the group the metallic character increases. Hence Sn is metallic.

What are the characteristics of actinides?
Actinides are a group of elements that have specific characteristics such as being radioactive, having high density, and being highly reactive. They also have variable oxidation states and exhibit metallic properties. Actinides have a series of elements in the periodic table from actinium through lawrencium.
Why does metallic nature increases down the group?
Metallic nature increases down a group because as you move down, the number of electron shells increases, leading to the outer electrons being further away from the nucleus. This results in greater atomic size and shielding of the outer electrons from the attractive force of the nucleus, decreasing the effective nuclear charge experienced by the outer electrons, making it easier for them to be lost and exhibit metallic characteristics.
Describe relationships between elements using the periodic table.HELP?
As you go across the periodic table from left the right the metallic nature decreases and the non- metallic nature increase. As we go down the group of atoms on the metal side the atoms get bigger and being metals loose electrons more easily therefore become more reactive As we go the group of atoms on the non metal side the atoms get smaller and are less likely for electrons to be gained
Is sulpur a nonmetal?
Yes, sulfur is a nonmetal. It is positioned in the nonmetal group on the periodic table due to its properties such as being a poor conductor of heat and electricity, and not having metallic luster.
Why are halogens used in your daily life?
§ Halogens are a group of non metallic elements that are placed in Group 7 of the Periodic Table. There are 5 elements that are considered to be a part of this group, and that are widely known as halogens. § Halogens are used in our daily life as they are very useful and decrease the chances of being sick or getting disease.
What is the classification of titanium?
Titanium is classified as a transition metal on the periodic table. It is known for its strength, low density, and resistance to corrosion, making it valuable in various industries such as aerospace, medical, and automotive.
What are III group elements in periodic table?
Group III elements in the periodic table are boron (B), aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). They are metallic elements with varying properties, such as being good conductors of electricity and having low melting points. These elements are commonly used in a variety of applications, from electronics to alloys.
Why is aluminum positioned in group 3 of the periodic table?
Aluminum is positioned in group 3 of the periodic table because it has three valence electrons in its outermost electron shell. This characteristic influences its chemical behavior, leading to the formation of trivalent cations (Al³⁺) when it reacts. Additionally, being part of the boron group, aluminum shares similar properties with other elements in this group, such as forming metallic bonds and exhibiting a range of oxidation states.
An unknown element is a soft metallic solid. It is highly reactive and has a low melting point. In which group of the periodic table is it most likely to be found?
Sodium - group 1
Is bromine classified as a metal non metal or metalloid?
Bromine is classified as a non-metal. It is a member of the halogen group in the periodic table and typically exhibits non-metallic properties such as being a poor conductor of heat and electricity.
How many element are there in the periodic table?
There are currently 118 elements in the periodic table, with elements beyond uranium being synthetic and not found in nature.
Why is metallic nature is not considered an innate property of metals?
Metallic nature is not considered an innate property of metals because some metals can lose their metallic properties under certain conditions, such as forming compounds with nonmetals or being subjected to extreme temperatures. Additionally, some nonmetals can exhibit metallic properties under specific conditions, blurring the distinction between metals and nonmetals based on metallic behavior.
