Explanation:

It should be seen that perhaps the intensity of Ebony timber is greater than the concentration. This can drown if this is heavier than water, but that will floating whether it is not viscous than air.

Why are some elements no longer found on earth
Iteru [2.4K]

Answer:

A synthetic element is one of 24 chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, or the explosion of an atomic bomb; thus, they are called "synthetic", "artificial", or "man-made".

Explanation: hope that helps

How are Kelvin scale and celcius scale similar <br>​
Alekssandra [29.7K]

Answer: The Kelvin scale is related to the Celsius scale. The difference between the freezing and boiling points of water is 100 degrees in each, so that the kelvin has the same magnitude as the degree Celsius.

Explanation:

Celsius is, or relates to, the Celsius temperature scale (previously known as the centigrade scale). The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale as well as serve as a unit increment to indicate a temperature interval(a difference between two temperatures or an uncertainty). “Celsius” is named after the Swedish astronomer Anders Celsius (1701-1744), who developed a similar temperature scale two years before his death.

K = °C + 273.15

°C = K − 273.15

Until 1954, 0 °C on the Celsius scale was defined as the melting point of ice and 100 °C was defined as the boiling point of water under a pressure of one standard atmosphere; this close equivalence is taught in schools today. However, the unit “degree Celsius” and the Celsius scale are currently, by international agreement, defined by two different points: absolute zero, and the triple point of specially prepared water. This definition also precisely relates the Celsius scale to the Kelvin scale, which is the SI base unit of temperature (symbol: K). Absolute zero—the temperature at which nothing could be colder and no heat energy remains in a substance—is defined as being precisely 0 K and −273.15 °C. The triple point of water is defined as being precisely 273.16 K and 0.01 °C.

What isotope is used for a standard for other atomic masses?
sergeinik [125]
Though the ratio of any two atom's masses was the same on either scale, it was horribly confusing, so in 1961, a compromise was reached. Instead of using either Hydrogen, or Oxygen as the standard, the isotope of Carbon<span> with 6 </span>protons<span> and 6 neutrons in its nucleus (</span>Carbon-12<span>) was given a mass of exactly 12.</span>

Why does group 18 in the periodic table not form ions?
alukav5142 [94]
Lets take a moment to list all the characteristics of the group 18 (also known as noble gases and/or group 8) elements: 
- They have 8 valence electrons. 
- Don't need ANY more electrons because their octet is full (stable). 
- Are stable 
- Not reactive
- Known as the noble gases

Now.. lets take some time to think about why elements want to form ions: 

Elements form ions to either gain or lose valence electrons to the element they bond with. This helps them GAIN a full octet. What is a full octet, you may ask? An octet is when an element has all 8 valence electrons and is stable, making it nonreactive. 

Why would an element with a full octet want to bond? It already has a full octet, it does not need to bond. 

That, my fellow Brainly user, is why the noble gases do not need to bond. 

I really do hope this helps! Enjoy, and good luck on the studies.
