Based on patterns in the periodic table, which ion has a stable valence electron configuration?
kifflom [539]

The ions of Noble gases, <em>group VIII</em> elements have a full octet configuration on their outermost shell and as such are highly stable.

The periodic table is a systematic arrangement of elements in order of their atomic numbers into a set of 8 columns each called groups and a set of 7 rows each called a period.

Elements are arranged in different groups according to the number of Valence electrons they have.

  • For instance, elements in the group I of the periodic table are highly electropositive and as such are highly reactive.

The same is evident in group 7 elements are highly electronegative and have high electron affinity and as such are unstable and reactive.

  • However, Noble gases, <em>group VIII</em> elements have a full octet configuration on their outermost shell and as such are highly stable.

Consequently, the <em>Noble gases ion</em> has a stable Valence electron configuration.

What are the two ways in which pressure can be increased?
icang [17]
Raised temperature, decreased volume.

Temperature and Pressure are directly related, when volume increases so does the your pressure.

Volume and Pressure are indirectly related. When volume decreases, your pressure will increase.

What makes calcium and nitrogen different list two differences
liberstina [14]

Answer:

the difference in electronegativity is so large (2.04) that the bonding electrons spend almost all their time on the nitrogen atom.

Explanation:

Because calcium loses 2 electrons to become Ca2+, and nitrogen gains 3 electrons to become N3−, you need two calcium atoms and three nitrogen atoms in order to form a neutral compound.

Hydrogen bromide is found in volcanic gas. What is the chemical formula for<br> this compound?
ruslelena [56]

Answer:

Hydrogen bromide, anhydrous appears as a colorless gas with a pungent irritating odor. Corrosive. Heavier than air. Prolonged exposure to fire or intense heat may result in the violent rupture and rocketing of the container. Long-term exposure to low concentrations or short-term exposure to high concentrations can result in adverse health effects from inhalation. Used to make other chemicals and as a catalyst in the manufacture of chemicals. Rate of onset: Immediate Persistence: Minutes to hours Odor threshold: 2 ppm Source/use/other hazard: Chemical manufacturing industry; very corrosive.

Explanation:

HBr
