What kind of element most often forms covalent bonds?
Typically the non metals form covalent bonds. Of course some non metals will also form anions when they react with metals. Some metals can also can form covalent bonds however as their electronegativity is low these bonds are often polar covalent
Why does sulphur have a covalent bond?
Sulfur Dioxide (SO2) is covalent. This is determined because the compound begins with a nonmetal. When any compound begins with a nonmetal, it is covalent. If it were to begin with a metal, such as Magnesium Bromide, then it would be ionic due to the fact that the compound begins with a metal.
Are ionic compounds more likely to dissolve in water than covalent compounds?
Often - yes. the reason they break apart is the hydration energy of the ions- many ionic compounds are soluble in water and dissociate into ions, however there are ionic solids such as CaCO3 which are not soluble. The bonds in covalent compunds are often not broken- for example thise in alkanes. However there are covalent compounds which do react with water and dissolve.
When a pair of electrons is shared between two atoms a covalent bond is said to have formed most often the pair is formed?
c. as each atom contributes one electron.
What is the example of binary covalent compounds?
A binary covalent compound is one that contains two substances joined by covalent bonds. For example, two nonmetals often join together to form covalent compounds. So, P2O5 (phosphorus pentoxide) is a binary covalent compound. H2O (dihydrogen monoxide) is another one. This is in contrast to binary ionic compounds, which are salts, and are formed by a metal combining with a nonmetal with ionic bonds.
What giant covalent structure is often used in semi conductors?
Silica
Do mechanical pencils work on standardized tests?
usually, no. in America #2 pencils are often required
What type of uses do we have for carbon?
used for fuel (coal), C-14 isotopeused in archeological dating, lubricants
What soft mineral often used in pencils?
color
When is a covalent bond often formed?
A covalent bond is typical for compounds between nonmetals.
Why do astronomers use pencils in space?
Pencils are often used in space because most pens rely on gravity to work and are therefore useless in orbit.
What is some thing a kindergarten student would use to write with?
Very young students are introduced to using pencils. Often the pencils and other writing tools are thick to make it easier to hold. They also write with crayons, markers, colored pencils, and chalk.
What kind of element most often forms covalent bonds?
Typically the non metals form covalent bonds. Of course some non metals will also form anions when they react with metals. Some metals can also can form covalent bonds however as their electronegativity is low these bonds are often polar covalent
Most often a covalent bond is formed by?
A covalent compound is always formed by the sharing of valence electrons(electrons in the last shell).
Is galena used in pencils?
No, we don't use galena is pencils. Galena is the primary ore of the metal lead, and this mineral, PbS, is recovered for that purpose. We also often recover silver as a byproduct of lead processing. It is graphite that is used in pencils, and the mineral graphite is an allotrope of carbon.
What is covalent water?
The water molecule has a covalent bond. Since there is no other kind of water, "covalent water" is redundant. That's what water is. There is no ionic water (although ionic compounds often dissolve in water).
What is the internal structure of a crystal often called?
the word crystalline is often used to describe the internal structure of crystals
