7 Which element has atoms that can form halide ions?(1) iodine (3) strontium
(2) silver (4) xenon

Answers

Answer 1
Answer:

The element that has atoms that can form halide ions is iodine.

What are halogens?

Halogens are nonmetals. At room temperature, fluorine and chlorine are gases, bromine is a liquid and Iodine and astatine are solids. Halogens are very reactive, the reactivity decreases from fluorine to astatine. Halogens do not exist in elemental form in nature. Astatine isotopes are radioactive with short half-lives.

One of the definitive properties of halogens is that they are highly reactive. Due to this nature, they can form different compounds such as halides, interhalogens and polyhalogenated compounds. We will look at them in brief below.

These are compounds formed by the reaction of halogens with metals. Metal halides can be highly ionic compounds, monomeric covalent compounds or polymeric covalentcompounds.

Therefore, The element that has atoms that can form halide ions is iodine.

Air is made up of different gases, such as oxygen, nitrogen, and carbon dioxide. Which statement best describes these three components of air? A)They are all classified as pure substances.

B)They cannot react with another substance.

C)They are chemically bonded to one another.

D)They can be classified as elements.

Answers

I think the correct answer from the choices listed above is option A. The three components of air are all classified as pure substances since they are not chemically bonded so they can be separated by certain processes and be present as a pure substance. Hope this answers the question.

The statement that best describes the three component of air is they are all classified as pure substances.

What are pure substances?

Pure substances are those substances which are made up of only one material and has specific and fixed structure. They are also called as elements.

Thus, the correct option is A) They are all classified as pure substances.

Answers

Answer:  Blocks harmful UV rays transports and distributes heat cycles essential elements: C, O, and N

Explanation:

The atmosphere is the integral part of the earth this typically includes gases which are necessary for sustaining lives on earth. The earth atmosphere forms a protective blanket around the inner earth which prevents the entry of majority of UV rays directly coming from the sun, This way atmosphere plays an important role in protecting the living beings from carcinogenic UV rays. It distributes the heat coming from the sunlight also it reflect back the absorb heat energy to the space acquired from the sun so as to maintain the balance of heat on planet earth.

It essentially plays an important role in circulation of essential gaseous elements like carbon, oxygen and nitrogen as these are required by the plants to conduct photosynthesis, respiration and protein synthesis respectively. Majorly all other life forms on earth are dependent on plants for food requirements therefore this cycling is beneficial for sustaining their lives too.
