The atomic mass unit (AMU or amu) of anelementis a measure of its atomicmass. Also known as thedalton(Da) orunified atomic mass unit(u), the AMU expresses both atomic masses and molecular masses. AMU is defined as one-twelfth the mass of anatomof carbon-12 (12C).12C is the most a...
- Hint: Atomic mass of an element can be determined from knowing the atomic number of the element and the number of neutrons present. In case of sodium the atomic number is 11.Formula used: Atomic number + Number of neutrons Complete step by step answer:...
How is the atomic mass of an element calculated? What is the atomic number of fluorine-19? How much atomic mass does bohrium have? If the atomic mass of an element is x, what is the mass in grams of 6.02 X 10^{23} atoms of the element?
To understand the relationship between atomic mass and the actual mass of one atom of an element, let's break it down step by step.Step 1: Define Atomic Mass Atomic mass is defined as the mass of one mole of atoms of an element
解答一 举报 An atomic weight (relative atomic mass) of an element from a specified source is the ratio of the average mass per atom of the element to 1/12 of the mass of an atom of 12C.and NA=6.02*10^23therefore ... 解析看不懂?免费查看同类题视频解析查看解答 ...
and neutrons are found in the nucleus of the atom, while the electrons are outside the nucleus. The atomic number is the number of protons, while the mass number is the number of protons and neutrons. If an element is not charged, the number of electrons will equal the number of ...

all the known elements in an informative array. Elements are arranged left to right and top to bottom in order of increasing atomic number. This order generally coincides with increasing atomic mass The different rows of elements are called periods. The period number of an element signifies the ...
Atomic Mass of Iron An element's atomic mass is equal to the sum of the individual particle masses of an atom. Atoms have three basic particles which include protons, neutrons, and electrons. The standard unit for measuring atomic mass is the Dalton (u). ...
1.how are the atomic numbers and the atomic masses of the elements related to how the elements are arranged on the periodic table?2.how does the number of electrons relate to the arrangement what is the different in the number of electrons in a 3rd period element and the 2nd period ...
