Metals are defined as those elements which have characteristic chemical and physical properties. The familiar types of metals are (iron, aluminium, copper, lead, zinc, silver, gold, etc.) are common elements.
Plastics are not corroded even if they come in contact with strong chemicals. This is because of their non-reactive nature with most materials. For example, the cleansing chemicals that we use at home are stored in plastic bottles, instead of metal containers. Show More ...
A metallic lattice is an arrangement of ions where a core of cations (positively charged ions) is surrounded by delocalized, freely moving valence electrons (outer shell electrons), known as a sea of electrons. This free movement contributes to some of the distinct properties of metals, including...
Are the alkaline earth metals more or less reactive than the alkali metals? Explain What Are Alkali Metals? Write its Properties and Characteristics Which of the following elements is an alkali metal?\A. K B. Kr C. Br D. Ca E. None of these ...
An example of a nonmetal element is helium. Helium is a noble gas which possesses very nonmetallic characteristics such as high electronegativity and high ionization energy. However, helium is exceptionally nonreactive and is not found in compounds like most metals are found in. Helium is also a...
Metals on Periodic Table The majority of the elements on the periodic table are metals. They are on the left side and in the center of the periodic table. (Except for Hydrogen, of course). Metals can form bonds with non-metals on the periodic table. They can also bond with ot...
Gold is a heavy metal in a group known as the transition metals. Gold is also known as a precious metal (as are platinum and silver). Large amounts of gold are still used in the manufacture of coins, medals, jewelry, and art. Gold also has a number of uses in industry, medicine,...
Helium is non-reactive, thus, it is used in the creation of a protective inert atmosphere in the manufacture of fiber optics and semiconductors. Helium is used to detect leaks in air-conditioning systems. It is also used to inflate air-bags in vehicles because it is non-toxic and diffuses...
The transition metals are located towards the middle of the periodic table between the highly reactive metals and the noble gases. Specifically, groups 3-12 are known as transition metals. These groups are in the D block of the periodic table. As mentioned previously, it is important to note...
But they are made of elements. What elements are in Group 7? The elements in Group 7 are called the halogens. They are highly reactive non-metals. They include fluorine, chlorine, bromine, iodine, and astitine.What is an Element? Elements are the tiny particles that make up matter. ...
