108 g of
Ag (108) Hint: To calculate the number of atoms first we have to calculate the number of moles of the given elements. Then the number of atoms will be equal to the product of the number of moles and Avogadro’s number.
What determines the number of an atom?
The number of protons
in a nucleus is called the atomic number and always equals the number of electrons in orbit about that nucleus (in a nonionized atom). Thus, all atoms that have the same number of protons–the atomic number–are atoms of the same element.
How do you find the maximum number of atoms?

Which part has maximum number of atoms?
Therefore, maximum number of atoms is present in
24 g of C
.
What is the maximum number of atoms in a molecule?
So the correct answer is Option
3
.
If it is a molecule, then one should not forget to change it to atoms by multiplying it by the number of atoms present in one individual molecule.
Who gave Avogadro number?
The term “Avogadro’s number” was first used by
French physicist Jean Baptiste Perrin
. In 1909 Perrin reported an estimate of Avogadro’s number based on his work on Brownian motion—the random movement of microscopic particles suspended in a liquid or gas.
Which has maximum number of atoms at NTP?
of moles x no. of atoms in one molecule xNA. Thus, we conclude that after calculation Option (B) has the maximum number of atoms 22.4L of CO2at STP = 18.066×
1023 atoms
.
Which model of the atom is the most accurate?
The electron cloud model
is currently the most sophisticated and widely accepted model of the atom. It retains the concept of the nucleus from Bohr and Rutherford’s models, but introduces a different definition of the motion of electrons around the nucleus.
What is the atomic mass equal to?
The atomic mass of an atom is an empirically measured property, which is equivalent to
the sum mass of protons, neutrons, and electrons that make up the atom
(with a small adjustment for nuclear binding energy).
What do you call the element from atomic number 57 71?
The elements from atomic number 57 to 71 are called
Lanthanides
. They are called lanthanides, since lanthanum is chemically identical to the elements in the sequence. … The lanthanides are between Barium and Hafnium.
Which has maximum number of atoms of oxygen?
Thus, the maximum number of oxygen atoms are present in [
12.044 times {10^{23}}] molecules of carbon dioxide
and option (d) is correct.
How many atoms are there in 56g of Fe?
This number, which represents the number of water molecules in 18g of water, or the number of iron atoms in 56g of iron, has a value of N=6.022 x 10^23
– 602 thousand billion billion
. The number of atoms in the human body is about 10,000 times higher than this.
Which has more number of atoms 1g of Na or 1g of MG?
Number of moles in Mg is less than Na. … of moles in Na=1/11 and in Mg = 1/12. Therefore
no. of atoms is more in Na than Mg
.
Can molecules have a high number of atoms?
In the kinetic theory of gases, the term molecule is often used for any gaseous particle regardless of its composition. This violates the definition that a molecule contain
two or more atoms
, since the noble gases are individual atoms.
What is the maximum atom?
The atomic mass of the substance is the sum of protons or electrons in an atom. For example, the atomic mass of
carbon
is 6 which means the number of electrons is six. … Thus, carbon has a maximum number of atoms.
Does no follow octet rule?
Nitric oxide: Nitric oxide (NO) is an example of a stable free radical.
It does not obey the octet rule on the nitrogen atom
. Each line around the atoms represents a pair of electrons.
