What factors contribute to the physical differences between one isotope of a particular element and another?
The physical differences between isotopes of an element are mainly due to variations in their atomic mass, which is determined by the number of neutrons in the nucleus. Isotopes of an element have the same number of protons but different numbers of neutrons, leading to differences in stability, radioactivity, and chemical behavior.
Which subatomic particle identifies an atom of a particular element?
It's the count of one of the subatomic particles in the nucleus, the proton, that is significant in this regard. For example, an atom is hydrogen if and only if it has one proton in its nucleus. It is neon if and only if it has ten protons in its nucleus.
When a nucleus decays what typically happens to the element?
After an element's nucleus decays, it becomes one or more different elements. The type of decay determines what the new element(s) will be. The type of decay the nucleus of an element will undergo depends on the particular isotope of the particular element in question. For example, alpha decay results in an new element which has 2 less protons and 2 less neutrons (decrease in atomic number of 2 and decrease in mass number of 4). Fission results in an element splitting into two new elements of various sizes, accompanied by the release of other random particles. The two new "daughter" element's masses plus the masses of the other released particles will add up (approximately) to the mass of the original element. There are many other types of decay which produce different decay products.
What is the equation for electron clouds layers?
Electron clouds in an atom are described by the electron probability distribution function, which is not a single equation but rather a three-dimensional probability density function. It is determined by solving the Schrödinger equation for the electron in the atom. This function gives the probability of finding an electron at a particular location in space around the nucleus.
What is the 3 dimensional region around a nucleus called?
The 3 dimensional region around a nucleus where an electron is likely to be found is called an electron cloud or electron orbital. This region represents the probability of finding an electron at a particular location within the atom.
In an s orbit the probability of finding an electron a particular distance from the nucleus does not depend on?
It would not depend on the direction with respect to the nucleus. The direction of the electron has no effect on the distance of the electron from the nucleus.
In an s orbital the probability of finding an electron a particular distance from the nucleus does NOT depend on?
In an s orbital, the probability of finding an electron at a particular distance from the nucleus does not depend on the direction in which the distance is measured or the orientation of the orbital. This is because s orbitals are spherically symmetric, meaning the electron has an equal likelihood of being found at any distance from the nucleus in all directions.
What configuration defines an isotope of the same element?
Isotopes of one particular element differ only in their number of neutrons in nucleus.
What describes the number of protons in the nucleus?
The Atomic Number of an element depicts the number of protons in that particular element.
Name for the atomic number?
The atomic number is the number of protons in the atomic nucleus of a particular element. Each element has its own unique atomic number.
How does the mass of a nucleus differ from the mass of an electron?
There is no simple answer.The mass of a nucleus depends on the number of neutrons and protons in the nucleus. The number of protons in the nucleus depends on the element. Moreover, the number of neutrons can vary between isotopes of the same element.
In an s orbital the probability of finding an electron a particular distance from the nucleus does not depend on a quantum mechanical model direction with respect to the nucleus the schrodinger e?
To the extent that I can make any sense of the question: Yes, the probability function for an s orbital is spherically symmetric and dependent on radial distance only.

Isotopes of an element have the same number of protons but different numbers of neutrons, leading to differences in stability, radioactivity, and chemical behavior.
In the modern quantum based atomic theory what is the name given to a particular space around the nucleus in which an electron moves?
In modern quantum-based atomic theory, the space around the nucleus in which an electron moves is known as an electron cloud or orbital. This is a region of space where there is a high probability of finding the electron. The electron cloud is described by the probability density function of the electron's position in the atom.
Which subatomic particle identifies an atom as that of particular element?
The number of protons defines the element.
Which subatomic particle identifies an atom of a particular element?
It's the count of one of the subatomic particles in the nucleus, the proton, that is significant in this regard. For example, an atom is hydrogen if and only if it has one proton in its nucleus. It is neon if and only if it has ten protons in its nucleus.
Is mass number the combining capacity of an element?
No, mass number is the number of neutrons and protons that exist within the nucleus of the atom for a particular element. It is based on the idea that most of the mass of an atom derives from the nucleus.
