The numbers on the elements represent their atomic number, which indicates the number of protons in the nucleus of an atom. This number is unique to each element and determines the element's identity. Additionally, the atomic number can help determine the element's position on the Periodic Table and its chemical properties.

What specific name is given to elements with atom numbers 90 to 103?
Elements with atomic numbers 90 to 103 are known as actinides.
What does lanthinide mean?
Lanthanides are a group of chemical elements that consist of elements with atomic numbers 57 to 71 on the periodic table. They are commonly used in various technologies due to their unique properties, such as their magnetic and optical behaviors.
Has oxidation numbers of plus 1 and -1?
Elements with oxidation numbers of +1 include elements in Group 1 of the periodic table, like hydrogen and sodium. Elements with oxidation numbers of -1 include elements in Group 17, like fluorine and chlorine.
What are the elements with atomic numbers 58-71 and 90-103 called?
The elements with atomic numbers 58-71 are called lanthanides, and those with atomic numbers 90-103 are called actinides. These elements are part of the inner transition metals and have unique properties due to their electron configurations.
Chemical elements with atomic numbers greater than that of uranium are called?
Transuranium elements. They typically have atomic numbers higher than 92 (uranium's atomic number) and are all artificially produced through nuclear reactions.
What is the sum of a set of numbers divided by the number of elements?
the mean or average of the set
What does find the average mean in math?
The average of a set of numbers is the sum of the numbers in the set divided by the number of elements in the set.
What is the mean in a group of numbers?
The mean of a set is the sum of all elements in the set divided by the cardinality of the set. In simple English: add up all the numbers, then divide the result by the number of numbers you had.
What is it called when the sum of a set of numbers divided by the number of the elements in the set?
That is called the average or mean.
Why do you find the mean of a set of numbers?
Count the number of elements in the set - call this number n. Add up all the numbers in the set - call this total t Then mean = t/n
How do you find out a median of a set of numbers?
If you order the numbers from the higher to the lowest, the median is the number separating the lower half of the numbers from the higher half of the numbers in the set. If you have an odd number of elements in the set then the median is in the middle of this descending ordered numbers. If you have an even number of elements then, in order to determine the median, you calculate the mean of the two middle values.
Are two numbers of 1 called elements?
two numbers with a product of 1 are called elements
What do the numbers mean in fertilizer?
The numbers of the fertiliser formula show the percentage of Nitrogen (N). Phosphorus (P) and Potash (K). There may also be a list of trace elements.
How are the actinide series elements created?
Elements with atomic numbers 89-94: natural elements.Elements with atomic numbers 95-98: artificial elements but they are also discoverd in nature as ultratraces.Elements with atomic numbers 99-103: artificial elements.
Is the mean of a list of numbers the maximum minus the minimum?
No. The maximum minus the minimum is the range. The mean is the sum of all elements of the list divided by the size of the list.
What do different elements have different numbers of?
Different elements have different numbers of protons. The number of protons identifies the element.
What is the median of numbers?
The "median" is the "number in the middle", if you sort the numbers. If (as here) the set has an even number of elements, you sort them, and then take the average (arithmetic mean) of the two numbers in the middle - in this example, the 5th and 6th number.
