Not only are they all polygons, but the numbers of their sides form a series of three consecutive integers ... a monotonically increasing arithmetic series with a common difference of ' 1 ' if you will.

Time Series.

A pair of parentheses is used to "enclose" numbers or letters in a series or elsewhere when enclosure is useful to understand the meaning. However, to separate the items in a series, only a comma and space after each item is needed, along with a conjunction to close the series. Examples: 1, 1, 2, and 3 are the first four numbers of a Fibonacci series; paragraphs (A), (B)(2), and (D) are the most relevant ones for this discussion.

The data that can best be represented by a line chart is time series data. This type of data shows how something changes over a long or short period of time.

The "golden ratio" is the limit of the ratio between consecutive terms of the Fibonacci series. That means that when you take two consecutive terms out of your Fibonacci series and divide them, the quotient is near the golden ratio, and the longer the piece of the Fibonacci series is that you use, the nearer the quotient is. The Fibonacci series has the property that it converges quickly, so even if you only look at the quotient of, say, the 9th and 10th terms, you're already going to be darn close. The exact value of the golden ratio is [1 + sqrt(5)]/2

Electronegativity is not typically a factor in determining the activity series of metals. The activity series is based on the reactivity of metals with acids and is typically determined by the tendency of a metal to lose electrons. Electronegativity, on the other hand, is a measure of the tendency of an atom to attract electrons in a compound.

Activity series are useful for single displacement reactions.

Sodium is high in the reactivity series. It is a highly reactive metal that can easily lose its outer electron to form a positive ion. Sodium reacts vigorously with water and oxygen, making it an active element in chemical reactions.

An element in the activity series can replace any element below it on the list. The ability of an element to react is referred to as the element's activity.

Yes, zinc is LESS reactive than potassium based on the activity series.

The list would include elements such as fluorine, chlorine, bromine, iodine, and astatine. These elements belong to the halogen group and exhibit decreasing chemical reactivity from top to bottom due to increasing atomic size and decreasing electronegativity.

The activity (or reactivity) series determines whether or not a metal will replace another one in a replacement reaction.See the Related Questions to the left for more information about the activity series.

Metals higher in the series will replace metal ions in solution that are lower in the series

According to the activity series, nickel will react with metals that are placed below it in the series. This means that nickel will react with metals such as silver, copper, and gold but not with metals placed above it like hydrogen, magnesium, or zinc.
