the two atoms belong to two different elements
What else can I help you with?
How do you know the number of protons an atoms has?
by the atomic number.
Do all elements in the same group have the same atomic mass?
No. Atoms of the same element can have different masses as the number of neutrons can vary. Atoms of the same element but with different masses are called isotopes.
How atoms of different element differ in their atomic structure?
This may be wrong, I'm not a expert in elements. But here's what I know: A element's atom has a specific number of protons in the nucleus. If you change the number of protons, you change the element. Forgive me if I'm wrong, but I'm only in 5th grade.
How do you know the difference between isotopes and an element?
Isotopes are atoms of an element having different number of electrons.
Has one less proton than N in the nucleus?
Nitrogen atoms have 7 protons in their nuclei. You can know this because the atomic number of nitrogen is 7, and the atomic number is the number of protons. So the element that has one less proton than nitrogen in the nuclei of its atoms is carbon, which is atomic number 6, so it has 6 protons in the nuclei of its atoms.
How do you know if two atoms are isotope?
They have the same number of protons and therefore the same chemical properties. But they have different numbers of neutrons and so the atomic masses are different and so are some physical properties.
Are all atoms of a given element identical to one another and different from atoms of other elements?
No. Some may have different numbers of neutrons. Atoms of the same element (atoms with the same number of protons in the nucleus) may have different numbers of neutrons, and so will have different masses. As an example, chlorine is a mixture of different isotopes with some of the atoms having different neutrons numbers.
Not all of Daltons rules were completely true as scientists later learned Matter is made of atoms and different elements are made of different atoms But not all atoms of a particular element are?
Dalton's atomic theory proposed that all atoms of a particular element are identical, which we now know is not entirely true. Isotopes are atoms of the same element with different numbers of neutrons, leading to variations in atomic mass. This discovery challenged Dalton's rule of identical atoms for a given element.
What else are you supposed to know about how atoms of different elements are different?
Atoms of each element have a specific number of protons.
What statement from daltons theory no longer true?
One statement from Dalton's atomic theory that is no longer considered true is that atoms of a given element are identical in mass and properties. We now know that atoms of the same element can have different masses due to the existence of isotopes, which are atoms with the same number of protons but different numbers of neutrons. Additionally, advancements in quantum mechanics and the understanding of atomic structure have revealed that atomic properties can vary significantly, challenging the idea of uniformity among atoms of the same element.
How do you find the mass number if you have the atomic number of an isotope?
Mass number is the sum of protons and neutrons in the nucleus of the atoms of a particular isotope. The atomic number is the number of protons, so you would also need to know the number of neutrons. You could not determine the mass number from the atomic number alone.
How many atoms of gold are in the bar?
The number of atoms in a bar of gold depends on the mass of the bar. To calculate the number of atoms, you would need to know the mass of the bar and the atomic mass of gold. You can use Avogadro's number to convert from grams to atoms.
