Sodium is categorized as a B. Element.
<u>The correct answers are </u>
- An atom of oxygen and the ion of oxygen both have 8 protons.
- As you add or remove neutrons from the nucleus, isotopes are formed.
Answer: Options A and D
<u>Explanation:</u>
An isotope of an element is formed by varying their number of neutrons and not on changing the number of electrons or protons. Similarly, an atom can be converted into an ion by adding or removing one or more electrons.
So the number of protons will not be changed for becoming an ion. Thus, the correct answers are that an atom of oxygen and ion of oxygen will be having 8 protons. Similarly, an isotope formation is possible on addition or removal of neutrons from the nucleus. All other options are not true as there will be no change in the number of electrons for isotope formation.
Answer:
The chemistry student will need to weigh 74.0g of chloroform.
Explanation:
Density relates mass and volume and 1 cm⁻³ = 1 mL:
1.48 g of chloroform ____ 1 cm⁻³ chloroform
m ____ 50.0 cm ⁻³ chloroform
m = 74.0 g of chloroform.
Therefore, the chemistry student will need to weigh 74.0g of chloroform.
It is improbable that any specie with d0 or d10 will exhibit color in coordination compounds.
- If the central metal atom or ion in a coordination complex contains unfilled d orbitals, the compound exhibits color.
- Weak d–d transitions that produce spectral bands in the visible spectrum are thought to be the source of the colors.
- Hence, It is improbable that any specie with d0 or d10 will exhibit color in coordination compounds.
<h3>What are coordination compounds?</h3>
- Molecules that have one or more metal centers bonded to ligands are known as coordination compounds (atoms, ions, or molecules that donate electrons to the metal).
- These complexes may have a charge or be neutral.
- The complex is stabilized by nearby counter-ions when it is charged.

Answer:
Through the process of condensation
Explanation:
Condensation is when gas converts to liquid. Carbon Dixide in the air will eventually convert to water and ruin the ocean water, thus affecting coral reefs. Please mark brainliest :)
