3)6 electrons and neon

In an atom there are levels of energy in the shell and sub shell  

This energy level is expressed in the form of electron configurations.  

The electron configuration Oxygen (atomic number = 8) :

1s²2s²2p⁴

Oxygen will try to achieve stability (according to the octet rule) by binding 2 electrons so that the 2p orbits are filled with 6 electrons, so that the configuration is stable like the noble gases Neon

₁₀Ne = 1s² 2s² 2p⁶

Answer:

A molecular formula tells us what atoms and how many of each type of atom are present in a molecule.

Explanation:

If only one atom of a specific type is present, no subscript is used.

For atoms that have two or more present, a subscript is written after the symbol for that atom.

Molecular formulas do not indicate how the atoms are arranged in the molecule.

- Hope this helps! -blazetoxic123

In a molecular formula, the subscripts represent the number of atoms of each element present in a molecule.

The molecular formula gives you the specific combination and quantity of atoms that make up a single molecule of a compound.

For example, consider the molecular formula of water, which is H₂O:

"H" represents hydrogen.

"O" represents oxygen.

The subscript "2" next to "H" indicates that there are two hydrogen atoms in one molecule of water.

The absence of a subscript next to "O" means that there is only one oxygen atom in one molecule of water.

So, the molecular formula H₂O tells us that a water molecule is composed of two hydrogen atoms and one oxygen atom bonded together.

Here are a few more examples to illustrate the importance of subscripts in molecular formulas:

Methane: CH₄ (One carbon atom and four hydrogen atoms)

Carbon dioxide: CO₂ (One carbon atom and two oxygen atoms)

Ethanol: C₂H₅OH (Two carbon atoms, six hydrogen atoms, and one oxygen atom)

The subscripts are crucial in distinguishing between different compounds with the same elements. For instance, carbon monoxide (CO) and carbon dioxide (CO₂) have different molecular structures and properties, even though they both contain carbon and oxygen. The subscripts in the molecular formula help to specify the unique arrangement of atoms within each molecule.

Answer:

To denote a stable inner configuration and it represents argon

Explanation:

The symbol [Ar] used in the electron configuration of potassium represents the inner electronic configuration of the element.

This argon atom is stable octet with completely filled shells. Most noble gases are used to write the electronic configuration of other atoms. The inner atomic orbitals of elements are similar to those of nearby noble gases.

A reflex is an involuntary, or automatic, action that your body does in response to something — without you even having to think about it. You don't decide to kick your leg, it just kicks. There are many types of reflexes and every healthy person has them. In fact, we're born with most of them

Answer: double displacement

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

The balanced chemical equation is:

[tex]3ZnS+2AlP\rightarrow Zn_3P_2+Al_2S_3[/tex]

Thus as ions get exchanged , it is double displacement reaction.

Answer:

10. The wavelength of the color red is 650 × 10⁻⁹ m

11. The frequency of the color red is approximately 4.6122 × 10¹⁴ Hertz

12. The corresponding energy  is approximately 3.058 × 10⁻¹⁹ J

Explanation:

10. Given that the wavelength, λ, of the color red is 650 nm, and one nanometer, nm = 10⁻⁹ m, we have;

The wavelength of the color red = 650 × 10⁻⁹ m

11. The frequency, v, of the color red is obtained from the relation, v = c/λ

Where;

c = The speed of light = 299,792,458 m/s

∴ v = 299,792,458/(650 × 10⁻⁹) ≈ 4.6122 × 10¹⁴ Hertz

12. Given that energy emitted by light, E = h × v, where E = 6.63 × 10⁻³⁴ J/s, we have;

E = 6.63 × 10⁻³⁴ J·s × 4.6122 × 10¹⁴ Hz ≈ 3.058 × 10⁻¹⁹ J

Therefore,  the corresponding energy, E ≈ 3.058 × 10⁻¹⁹ J.

The volume using the cylinder formula  : V=πr²h

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

[tex]\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]

This experiment is an illustration of Charles's law, to determine the relationship between temperature and gas volume

If a certain amount of gas is heated, the volume will increase

So in this experiment, the temperature was changed as an independent variable and tube volume as a fixed variable

Because the tube is cylindrical, to find the volume using the cylinder formula

[tex]\tt V=\pi.r^2.h[/tex]

Meanwhile, to find the radius, you can use a caliper to measure the diameter of the tube and the result will be divided by 2

Explanation:

Diamonds are made up of carbon that has been placed under extreme heat and pressure conditions.

These conditions of high pressure and temperature can only be found within the subsurface. As you go deeper to the mantle, the geothermal gradient rises significantly.

Also, the overburden pressure will also be high.

These processes can also occur on other planets and some can be associated to the earth times when the earth was being formed.

The condition at which diamond forms confers some of the distinct natural properties that typifies it.
