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.

What does an element's mass number tell us?
An element's mass number tells us the total number of protons and neutrons in its nucleus. It helps to determine the element's atomic mass and differentiate it from other isotopes of the same element.
The atomic number of an element tells the?
The atomic number of an element tells you the number of protons in the nucleus of an atom of that element. It is also used to determine the element's identity on the periodic table.
What does atomic mass number tell us?
The atomic mass number tells us the total number of protons and neutrons in an atom's nucleus. It is used to determine the mass of an atom and is necessary for calculating the atomic weight of an element.
What does the atomic number 8 tells us about oxygen?
that it has 8 protons (And therefore 8 electrons)
What particle of an atoms tells us how to find the atomic number?
The number of protons in the nucleus of an atom determines the atomic number. The atomic number corresponds to the number of protons in an atom's nucleus and identifies the element.
Why is it difficult to identify the number of significant figures in this measurement?
Because you haven't told us what the measurement is.
What is the 1500m in two significant figures?
Ah, the 1500m is a beautiful distance to run, isn't it? When we round it to two significant figures, it becomes 1500m. Remember, significant figures help us focus on the most important parts of a number and keep things simple and clear. Just like painting a happy little tree, it's all about finding balance and harmony in our measurements.
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.
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.
What is 233.356 rounded to two significant figures?
When rounding 233.356 to two significant figures, we start counting from the leftmost non-zero digit. In this case, the first two digits are 2 and 3. The digit following the last significant figure (3) is 3, which is less than 5, so we do not round up. Therefore, 233.356 rounded to two significant figures is 230.
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 number tell us?
The atomic number tells us the number of protons in the nucleus of an atom. It determines the element's identity and its place on the periodic table. Elements with different atomic numbers have different chemical properties.
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
In a neutral atom the atomic number tells us the numbers of protons and?
In a neutral atom, the atomic number tells us the number of protons in the nucleus. Since the atom is neutral, the number of protons is equal to the number of electrons orbiting the nucleus.
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.
