Which is an example of a plasma that occurs in nature?
koban [17]

The answer is: the radiant sun.

There are five fundamental states of matter (gas, liquid, solid, plasma and Bose–Einstein condensate).

Plasma is a an ionised gas with highly electrical conductivity.

It is an electrically neutral with positive and negative particles.

Plasma may be the most abundant form of matter in the universe.

Plasma was first described by chemist Irving Langmuir.

Plasma can be artificially made by heating a neutral gas to a strong electromagnetic field.

For each main-group element, what is the relationship between it's group number and the number if valence electrons that the gro
avanturin [10]

Explanation:

The representative elements are in columns A1 - A7. In an 18 column table the map is as follows:

A1 = column 1, hydrogen + alkali metals have 1 valence

A2 = column 2, alkaline earth metals have 2 valence

A3 = column 13, Boron family have 3 valence

A4 = column 14, Carbon group have 4 valence

A5 = column 15, Nitrogen family have 5 valence

A6 = column 16, Oxygen column - chalcogens have 6 valence

A7 = column 17, Fluorine column - halogens have 7 valence

<u>The group number of the representative elements = the number of valence electrons.</u>

Where are the noble gases on the periodic table and what characteristics do they have?
OlgaM077 [116]
<span>the noble gases are those who occupy the eighth group of the periodic table and are so called because having the complete valence shell do not need to form bonds with other atoms and are thus in atomic form ...
</span>
The noble gases (also called rare gases) are of the inert gases that constitute the eighteenth [1] group of the periodic table of the elements, ie, the right-most column. They consist of atoms with electron shells full. It includes the following elements: helium neon argon krypton xenon radon Ununoctium <span>Sometimes they (particularly helium) are located together with other gases (mostly nitrogen and methane) into endogenous sources; helium of endogenous origin comes from the decomposition of radioactive elements present in the subsurface that emit α particles (ie ions He2 +): These oxidized species present in the soil and become elio.I atoms of the noble gases are all monatomic gas, not easily liquefiable, present the atmosphere in different percentages; the most common is argon which is approximately the 0.932%.</span>

Write the following numbers in standard notation. Use a terminal decimal point when needed.
ololo11 [35]

The standard notation of 1.0070x10⁴ is 10070

To express enormous figures which are in standard notation like 1,300,000 or exceedingly minuscule quantities like 0.0000000000045, scientists use scientific notation. Scientific notation, also referred to as exponential form, is one of the earliest mathematical techniques. It is well regarded by practitioners. People use scientific notation to handle situations where numbers are too large or too small to be calculated easily. Scientists, engineers, and mathematicians all use this technique. where as standard notation is way writing numbers in normal decimal form. The scientific method id most convenient denoting numbers as the numbers will be either too big or too small.

To learn more about standard notation:
