step by step

Na(sodium)=2.8.1

Cl (Chlorine)=2.8.7. sodium will give the chlorine the 1 valence electron to become stable ions.

answer

pottasium. (2.8.8.1) and Flourine(2.7)

Some soils, like clay, hold water tightly. Other soils, like sand, let the water run through. What property of soils is MOST IMP

RoseWind [281]

Most likely the second one (sand letting water run through it) because if you are trying to determine how what moves through soil You would want the one the one that can do that:)

Who established atomic numbers as the basis for organizing the periodic table?

Jobisdone [24]

Answer:

Henry Moseley.

Explanation:

Hello,

Henry Moseley's work stated that it is better to organize the periodic table in the light of the atomic number (which accounts for the amount of protons and electrons) instead of the atomic mass, because atomic numbers are not arbitrarily assigned as long as they have the aforesaid physical basis.

Best regards.

The combination of oxygen with other substances to produce new chemical products is called

Flauer [41]

Answer:

The combination of oxygen with other substances to produce new chemical products is called Oxidation.

Explanation:

Oxidation reactions are defined as,

In terms of Inorganic chemistry:

(i) Removal of Electrons:

Example: Mg → Mg²⁺ + 2 e⁻

(ii) Addition of Oxygen:

Example: 2 Mg + O₂ → 2 MgO

In terms of Organic chemistry:

(i) Addition of Electrons:

Example: Cl₂ + 2 e⁻ → 2 Cl⁻

(ii) Addition of Hydrogen:

Example: H₂CCH₂ + H₂ → H₃CCH₃

Which substances were ionic?

horsena [70]

<h3>Sodium chloride and Sodium bicarbonate are ionic substances</h3><h3>Further explanation </h3>

Atoms have different stability. Unstable atomic atoms will try to form stable electron configurations like those of noble gases. Where noble gases have the number of outer electrons 2 or 8

The formation of electron configurations such as noble gases can be done by sharing electrons with covalent bonds or hand over electrons with ionic bonds

Generally, ionic bonds occur in metals and nonmetallic elements.

While covalent bonds occur because of the use of shared electrons. In general, this bond occurs between nonmetallic elements, which has the same electron attraction

Characteristics of ionic compounds include: solid / crystalline form, soluble in water, conduct electricity

Let see the answer choices

It is a covalent compound because part of the hydrocarbon, a liquid that forms a bond between elements C, H and O, and does not dissolve in water (floats on water)

Cornstarch

Obtained from corn which contains glucose which is a carbohydrate. It does not dissolve in water. Contains a bond between C, H and O. Includes covalent compounds
