The lab question is “based on a substance’s properties, how can you determine whether its bonds are ionic or covalent? ” fill in the box to answer this question with a hypothesis. hypothesis: if a substance contains ionic bonds, then its properties would include . .

The bonds between ionic molecules are very strong. The ionic molecules are crystalline solid, have high boiling point, and show electric conductivity in the solution.

Ionic Bond:

This bond is formed between two ions where one is positive and another is negative. Positively charged elements give electrons to negatively charged elements to complete octet.

Example:

Properties of Ionic Compound:

Properties of covalent Compound:

Hence, If a substance contains ionic bonds, then its properties would include solid crystalline state, high melting point and conduct electricity in the solution.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
