A nonmetal is a chemical element that mostly lacks the characteristics of a metal. Physically, a nonmetal tends to have a relatively low melting point, boiling point, and density. A nonmetal is typically brittle when solid and usually has poor thermal conductivity and electrical conductivity. Chemi...
Other members of the family are less abundant and are comparatively less useful. Hence, boron is the nonmetal in the Boron family. Suggest Corrections Q. An element belongs to the 3rd period and Group IIIA (13) of the periodic table.State: (a) the number of valence electrons, (b) the ...
Element: Matter is anything that has mass and is occupying some space in the universe. The matter is classified into pure substances and mixtures. Element is a pure substance. Answer and Explanation: Learn more about this topic: Chemical Symbol | Overview, Examples & Origin ...
Which element is a metalloid? (a) iron (b) silicon (c) sodium (d) cadmium. What are the characteristics of metalloids? On the periodic table, what are elements from the 7A(17) group called? Which of the following elements is a nonmetal? a. K b. Be c. Ce d. N ...
What does the atomic number of an element tell you? What element from the first 10 elements would be most similar in properties to the element of atomic number 115 (presently unknown)? Which of the following elements is a nonmetal? a. K b. Be c. Ce d. N ...
What factors influence the strength of a binary acid? The strength of a binary acid is influenced by the bond strength between hydrogen and the other nonmetal element; weaker bonds result in stronger acids. 6 Can you name a ternary acid and its application? Sulfuric acid (H2SO4) is a tern...
Silicon is everywhere. So, where did all this stuff come from in the first place? Silicon is a primordial element, created during the Big Bang or by nuclear fusion during a supernova. It's the eighth most abundant element in the observable Universe, but the third most abundant on Earth....
but there is some scientific debate over whether they are true metalloids. These elements are often brittle and shiny in appearance, but there is no strict definition of the properties and characteristics required to define an element as a metalloid. The term semi-metals is sometimes also used ...
There are three main types of bonding: ionic (between metal and nonmetal), covalent (between nonmetals), and metallic (between metals). Ionic bonding occurs when a cation (positive particle) is attracted to an anion (negative particle) due to the fact that opposites attract. Covalent bonding ...
Boron is a metalloid: a type of element that shares properties with both metals and nonmetals. Boron's ability to conduct electricity, yet resist heat like a nonmetal, makes it a crucial component in semiconductors. Borax (chemistry) The sodium salt of boric acid, Na2B4O7, either anhydrous...
