A cycloalkane is a regular alkane with a ring or loop. An example is cyclohexane, which is a ring of 6 carbon atoms, each bonded to 2 hydrogen atoms
<span>1. The number of valence electrons increases as you go from left to right across a period. This is because the number of electrons increases, so another electron will be added to the outer shell.
2. Group 6A elements will have 6 valence elecrons, while Group 2A elements only have 2, therefore Group 6A elements have more valence electrons that Group 2A elements.
3. Fluorine has a smaller atomic size than the other halogens (Cl, Br, I), so its valence electrons are nearer to its nucleus. This means that the attractive forces are stronger, so when another electron (from another atom) draws near the F atom, it is more likely that the electron will be pulled toward the nucleus and react with the F atom</span>.
Answer:
CaKr Na2S BaCl3 MgF. CaKr-Kr is a noble gas Na2S-not balanced BaCl3-not balanced MgF-not balanced.
Explanation:
Answer:
<u><em>A. They don't form compounds</em></u>
Explanation:
- High density: The strong bonding between the atoms in transition metals cause them to be tightly held together, creating a high density. Colored compounds: Transition metals tend to form more colored compounds than other elements, either in solid form or dissolved in a solvent.
