What does the number of significant figures in a number tells us about it?

It means to count and consider all non-zero digits to the extreme right or left of the non-zero digits. For example, 1,038,000 and 0.00005678 both have only 4 sig. figures. The zeroes among the non-zero digits are significant because they correctly position the other significant digits themselves. The outside zeroes merely indicate the overall position of the entire significant group. Thus we term them insignificant, even though they are important too, as place holders.

The atomic number of an element tells the?
atomic number tells us the number of protons and electrons in the given atom. As Atomic No. = no. of protons = No. of electrons
What does an element's mass number tell us?
The mass number tells you the number of Protons and Neutrons in an atomic nucleus.
What particle of an atoms tells us how to find the atomic number?
the number of protons in each atom
What does atomic mass number tell us?
Type your answer here..The Atomic Mass Unit tells us that ,How heavy a substance as compare to the other.
What does the atomic number 8 tells us about oxygen?
that it has 8 protons (And therefore 8 electrons)
Why is it difficult to identify the number of significant figures in this measurement?
Because you haven't told us what the measurement is.
How many liters in 1900 gallons?
1 US gallon = 3.78541178 liters 1900gal x (3.78541178L/1gal) = 7200L *Rounded to the correct number of significant figures.
What tells us how many times a number is used as a factor?
The exponent tells us how many times a number is used as a factor.
What does the atomic number tell us?
it tells us the number on the periodic table and it also tells us how many protons and nuetrons and electrons are in the atom within the nuecles.
Is it the top number that tells us how many beats are in a bar?
Yes, and the bottom number tells us what kind of note gets one beat.
The atomic number of an element tells the?
atomic number tells us the number of protons and electrons in the given atom. As Atomic No. = no. of protons = No. of electrons
What does an element's mass number tell us?
The mass number tells you the number of Protons and Neutrons in an atomic nucleus.
What do significant figures tell us about a measurement?
Used properly,they tell us how precise it is. The rule of thumb for significant figures is "every digit you're sure of, and one you're not". So if you're positive something is 123 and a bit, you could do 123.3 or 123.7 or whatever based on your best guess to the last digit.
What does the absolute value of a number tells us?
One of the things that is tells you is how far away it is from zero.
What does the atomic tell us?
it tells us the number on the Periodic Table and it also tells us how many protons and nuetrons and electrons are in the atom within the nuecles.
What does the atomic mass tell us?
it tells us that the number is equal to the number of protons plus the number of nuetrons in the nucleus of an atom
What does the atomic number tells you?
The atomic number tells you how many protons and electrons are in a specific element.Atomic number tells us about protons. Number of protons that atom contains.
