Ivanshal [37]2 years ago
8 0

The atomic number of an atom that has six protons, six neutrons, and six electrons is 6. And the element is carbon.

Carbon is known as a tetravalent compound.

It has four electrons in its outermost shell. It forms a covalent bond with other compounds.

The number of neutrons. = 6

Number of electrons = 6

Number of protons = 6

So the atomic number of the compound is,

The atomic number of an element = Number of protons present in its nucleus

The number of protons given in the compound is 6.

So the atomic number of the compound is also 6.

Carbon has six atomic numbers.

Therefore, the atomic number of an atom that has six protons, six neutrons, and six electrons is 6. And the element is carbon.

Examine the three isotopes of potassium (K) below.
liubo4ka [24]

<u>Answer:</u> The correct answer is Potassium-39, Potassium-40, Potassium-41

<u>Explanation:</u>

Atomic number is defined as the number of protons present in an atom.

Mass number is defined as the sum of number of protons and number of neutrons present in an atom. It is represented as A.

A = Mass number = Number of neutrons + Number of protons.

For the given isotopes of potassium:

Atomic number of potassium is 19.

<u>For potassium-41 isotope:</u>

Mass number = 41

Number of neutrons = 41 - 19 = 22

<u>For potassium-39 isotope:</u>

Mass number = 39

Number of neutrons = 39 - 19 = 20

<u>For potassium-40 isotope:</u>

Mass number = 40

Number of neutrons = 40 - 19 = 21

The most number of neutrons are in potassium-41 isotope and the least number of neutrons are in potassium-39

Hence, the correct answer is Potassium-39, Potassium-40, Potassium-41

After decaying for 48 hours, l/16 of the original mass of a radioisotope sample remains unchanged. What is the half-life of this
ivolga24 [154]

After the first half-life, 1/2 is unchanged. After the 2nd one, 1/4 remains. After the 4th one, 1/16 remains. So you have 4 half-lives in 48 hours, the half-life is thus 12 hours.

what is the color of a fabric that absorbs electromagnetic radiation of wavelengths between 400 and 500nm
Umnica [9.8K]

Answer:

Either of the three colors

Violet , indigo , Blue

Explanation:

The different ranges of color produced as per the electromagnetic spectrum are as follows  

• Violet:   400 - 420 nm

• Indigo:   420 - 440 nm

• Blue:   440 - 490 nm

• Green:   490 - 570 nm

• Yellow:   570 - 585 nm

• Orange:   585 - 620 nm

• Red:   620 - 780 nm

A material absorbing light in the range of 400-500 nm can have three colors –  

•  Violet:   400 - 420 nm

• Indigo:   420 - 440 nm

• Blue:   440 - 490 nm
