What is the atomic mass on the periodic table?
Each element on the periodic table has two numbers: the atomic number and the relative atomic mass. The atomic number is the number of protons in the nucleus, and the relative atomic mass is the total number of protons and neutrons (so the difference between them is the number of neutrons). The relative atomic mass is always the higher of the two.
How do you find the density with only mass?
You can't. There are two measurements needed: MASS and Volume
What are two ways you can find the volume of a shape?
The two ways are:empirical: measure ittheoretical: calculate it (using formulae).
What are two ways to write 100203?
The number in the two spot is in the hundredth place.
How many ways can you find to tesselate tile two-dimensional space with spidron arms?
it is an infinate number. if you keep adding layer after layer to get different combinations, you'll find out that it'll repeat
What are the two ways that an elements symbol can be represented?
Atomic mass and Atomic number
Atomic number of 2 and atomic mass of 4 how many neutrons?
To find the number of neutrons simply subtract the atomic number from the atomic mass. In this case there are two neutrons.
What two ways do isotopes differ?
- different atomic mass - different number of neutrons - different nuclear properties - etc.
To find the number of neutrons is an isotope start with the mass number and what?
To find the number of neutrons in an isotope, subtract the atomic number (number of protons) from the mass number (sum of protons and neutrons). The difference will give you the number of neutrons in the nucleus.
How find 1 percent of a number?
Two ways. Pick the one you prefer.1). Divide the number by 100.2). Move the number's decimal point two places to the left.
What is a sentence with the word mass number?
"mass number" is not "the/a" word, it is two words.
What do you do to find the mass of an object?
Two ways to find the mass of an object:1). Compare it with an object whose mass is known, for example on a balance scale, using a set of calibrated masses.2). Weigh the unknown mass. Since we know the acceleration of gravity on earth (9.8 meters/32.2 feet per second2), we can divide the weight by the acceleration of gravity to find the mass.
An atom of carbon whose mass number is 14 differs from an atom of carbon whose mass number is 12 in that it has?
neutrons, subtract the atomic number from the mass number to find the number of neutrons, atomic number is the number is the amount of protons, atomic mass is the average mass of one mole of atoms. each particle wieghing one amu (atomic mass unit)
How do you find out how many neutrons are in an atom?
You have to subtract the number of protons in the element by the Mass number. You find the # of protons because it the same as the Atomic number. And find the Mass Number by rounding the Atomic Mass to the nearest Whole number.
What are the two ways to measure the density of an object?
The two ways to measure the density of an object are by using its mass and volume. You can calculate density by dividing the object's mass by its volume, or by measuring the displacement of water when the object is submerged in it.
Why do two isotopes of the element have the same atomic number but different mass numbers?
why do you think i looked on this thing to find the answer.YOU TELL ME!
What is the Mass number of helium atom that has two protons and two neutrons?
4 because the mass number equals protons plus neutrons. Which is 4.
