Answer:
The particles in a solid vibrate in place.
Explanation:
The particles in a solid are close and tightly packed together so they have no room to flow past each other like the particles in a liquid can.
Hope this helps!
Answer:
D. They react readily with oxygen in the air
14 since K has 1 valence but there’s two so 2 valence for k and oxygen has 6 but there’s two so 12
C. PH3 represents a compound commonly known as phosphine, whose IUPAC name is phosphorus trihydride.
<h3>What type of bond is PH3?</h3>
The electronegativity of PH3 found in the Periodic Table of the Period attracts covalent electron pairs and creates covalent bonds. However, because the electrons are not bound, asymmetrical rate distribution occurs. Therefore, PH3 is a polar molecule with a non-polar covalent bond and currently has no polar bond.
<h3 /><h3>What defines a covalent bond?</h3>
A covalent bond consists of sharing one or more electron pairs between two atoms. These electrons are attracted to two nuclei at the same time. Covalent bonds are formed when the difference in electronegativity between two atoms is too small for electron transfer to form ions.
