What is the mass number of the element Na?
Sodium is a metal element. Mass number of it is 23.
What is the atomic mass number of sodium?
Sodium is a meta element. Atomic mass of it is 23.
Do you find the number of moles of an element?
To find the number of moles of an element, you need to divide the given mass of the element by its molar mass. The formula is: moles = mass / molar mass.
If the atomic mass of an element is x what is the mass in grams of 6.021023 atoms of the element?
To find the mass of 6.02 x 10^23 atoms of an element, you would multiply the atomic mass of the element (x) by Avogadro's number (6.02 x 10^23 molecules/mol) to get the mass in grams. The result would be x grams.
How many neutrons are in 23 11Na plus 1?
Elements differ from one another according to the number of protons in the atoms' nuclei. Essentially, the number of protons indicate the element (not its reactivity).11 is the atomic number of SodiumAtomic number (in this case, 11,) is the number of protons in the element.The 23 is telling you the atomic mass of the element (usually listed underneath the element symbol on the periodic table). The atomic mass of Sodium on the table is usually around 22.989.... so rounded to 23 for you in this question.The atomic mass is the mass of protons plus neutrons(each about 1 atomic mass units).Electron are so relatively light they do not significantly contribute to the mass of an element.
What is the mass number of the element Na?
Sodium is a metal element. Mass number of it is 23.
Which element has thea mass number of 23 and12 nuetrons?
Sodium is a metal element. Atomic mass number of it is 23.
What is the atomic number and the mass number of an element with 20 atomic number and 23 mass number?
The element with atomic number 20 is calcium. The mass number 23 indicates the total number of protons and neutrons in the nucleus of the atom. Since the mass number is 23 and the atomic number is 20, the number of neutrons in this calcium atom would be 3 (23 - 20).
What is the atomic mass number of sodium?
Sodium is a meta element. Atomic mass of it is 23.
What is the mass number of element sodium?
23
Element with the atomic number 23?
The element with atomic number 23 is vanadium. It is a transition metal known for its strength and corrosion resistance. Vanadium is commonly used in steel production and in the manufacturing of various alloys.
What is the mass number of soudium?
Sodium is a metal element. Atomic mass of it is 23.
What is the mass number of an atom with 11 protons 11 electrons 12 neutrons?
The mass number is the sum of protons and neutrons in an atom. In this case, the atom has 11 protons and 12 neutrons, so the mass number is 11 + 12 = 23.
What element has a atomic number of 11 and mass number of 23?
Sodium, symbol is Na
If an atom has 11 protons 12 neutrons and 11 electrons what is the identify of the element and it's mass number?
The element is sodium with a mass number of 23. Sodium has 11 protons and thus an atomic number of 11. The mass number is calculated by adding the number of protons and neutrons, which gives 23 in this case.
What is the mass number of a sodium atom?
The mass number of a sodium atom is 23. It is determined by the sum of protons and neutrons in the nucleus. Sodium has 11 protons and typically 12 neutrons, giving it a total mass number of 23.
Do you find the number of moles of an element?
To find the number of moles of an element, you need to divide the given mass of the element by its molar mass. The formula is: moles = mass / molar mass.
