1 (a) Elements in the same group tend to form products with similar physical properties.However, the oxides of carbon and silicon have very different physical structures. While CO2 exists as a gas at room temperature, SiO2 is a solid.(i) Explain, in terms of structure and bonding, the di...
If two metals both have the same color, have similar densities, and are about the same size, but one is shiny and the other is dull, they can be separated based on the physical property known as: a. malleability b. ductility c. hardness d. lus...
In year 1817 ___ tried to sort the elements with the same properties in groups. View Solution Two elements that have similar properties because they have the same number of valence electrons are View Solution Exams IIT JEE NEET UP Board...
To answer the question "Elements in the same group have chemical properties. (similar/different)", we can follow these steps:Step 1: Understand the Concept of Groups in the Periodic Table - The periodic table is organized into
What are two of the properties of non-metallic elements? Name the rare-earth elements with atomic numbers 57 to 71, having properties similar to lanthanum. List the elements that has properties of both metals and nonmetals. What do the alkali metals all have...
Answer to: (a) What are the properties of elements and compounds? (b) How are properties of a compound related to elements that comprise it? By...
Two elements in the same package cannot have the same name, so when you duplicate an element, a new name is assigned to the duplicate. Tip:By default, pressing the CTRL key while dragging an element creates a copy of the element. You can change the default behavior so that CTRL+drag cr...
A: Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. They share the same chemical properties because they have the same number of outer electrons, which determine reactivity. Q: What are the trends in Group 1 (alkali metals)? A: In ...
A further important fact is that stellar winds lead to dust formation, which also takes place in supernova explosions. Isotopic abundance properties in meteoritic inclusions can directly point back to dust grains from such events. New challenges have come with gravitational wave observations of ...
Elements to the left of this line (with the exception of hydrogen) are metals, while those to the right are nonmetals. This division is for convenience only; elements bordering the line –the metalloids-have properties characteristics of both metals and nonmetals. It may be seen that most ...
