<h3><u>Answer;</u></h3>
All types of
Crystals can have <em><u>all types of</u></em> bonds between their atoms.
<h3><u>Explanation</u>;</h3>
- <em><u>Crystals are solid materials which contains atoms, molecules or ions that are arranged in a complex structure forming a crystal lattice.</u></em>
- <u><em>Crystals may have all types of bonds</em></u>, these includes; <em><u>ionic bonds, formed as a result of transfer between a metallic bond and a non-metal atom, Covalent bond, formed as a result of sharing electrons between non metal atoms, hydrogen bonds, metallic bonds Van der Waals bonds, etc.</u></em>
Answer:
Fusion rates and star evolution increase rapidly because of the conversion of hydrogen molecules to helium.
Explanation:
At the early stage of a star mass, hydrogen atoms are produced. After a few billion years, these hydrogen atoms formed at the core of the star mass begin to fuse on the external side of the core. Hydrogen atoms get rapidly fused, resulting to a contraction of the star core, and as more hydrogen atoms get fused, helium atoms are formed.
This action results into rapid into a rapid and violent burning action of hydrogen atoms around the core.
