Lets take a moment to list all the characteristics of the group 18 (also known as noble gases and/or group 8) elements:
- They have 8 valence electrons.
- Don't need ANY more electrons because their octet is full (stable).
- Are stable
- Not reactive
- Known as the noble gases
Now.. lets take some time to think about why elements want to form ions:
Elements form ions to either gain or lose valence electrons to the element they bond with. This helps them GAIN a full octet. What is a full octet, you may ask? An octet is when an element has all 8 valence electrons and is stable, making it nonreactive.
Why would an element with a full octet want to bond? It already has a full octet, it does not need to bond.
That, my fellow Brainly user, is why the noble gases do not need to bond.
I really do hope this helps! Enjoy, and good luck on the studies.
I believe it would be the color Red.
True- the finches would eat different sizes nuts and seeds as they would occupy different niches over times which lead to differences in beak sizes within the island
Answer:
2 51 × 10^-5mol/L
Explanation:
The concentration of hydrogen ions can be calculated using the formula below :
pH = -log [H+]
pH = 4.6
[H+] = ?
[H+] = Antilog (-4.6)
[H+] = 2 51 × 10^-5mol/L
Answer:
Water is a polar solvent
Explanation:
We must know that pure dry hydrogen chloride gas does not show any acidic property.
In fact, when hydrogen chloride is dissolved in water, it breaks up into H3O^+ ions and Cl^- ions. This is possible because water is a polar solvent and assists the ionization of HCl.
In nonpolar solvents such as benzene, hydrogen chloride gas is not ionized hence it does not show any acidic property in a benzene solution.
