Why do nuclei of some atoms of the same elements differ in their number of neutrons?
Because of isotopes
How do the number of neutrons and protons in nuclei of carbon-14 and nitrogen-14 differ?
Carbon is atomic number 6, so its atoms have 6 protons in their nuclei. Carbon-14 atoms have 8 neutrons in addition to the 6 protons. Nitrogen is atomic number 7, so its atoms have 7 protons in their nuclei. Nitrogen-14 atoms have 7 neutrons in addition to the 7 protons.
Isotopes of hydrogen differ in what?
Isotopes (of hydrogen) differ in the number of neutrons in the nucleus of the atoms.
What are element that differ in the number of neutrons known as?
Isotopes are elements that differ in the number of neutrons they have. Isotopes of an element have the same number of protons in their nuclei but different numbers of neutrons, resulting in varying atomic weights.
How do the atoms of one element differ from those of another element?
Atoms of different elements differ in their number of protons, which determines the element's identity. Each element has a unique number of protons in its nucleus, leading to distinct chemical properties. Differences in the number of neutrons and electrons can result in isotopes and ions of the same element.
What are Atoms that vary in the number of neutrons found in their nuclei called?
Atoms that vary in the number of neutrons found in their nuclei are called isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, which can lead to variations in their atomic mass.
Neutral atoms of the same element can differ in their number of what?
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
Atoms that have the same number of protons but differ in the number of neutrons is what?
Isotopes.
Are compound and isotope the same?
No.Compounds are comprised of 2 or more atoms bonded together. For example, water is H2O, containing two hydrogen atoms and one oxygen atom per molecule.Isotopes are atoms of the same atomic number, i.e. they have the same number of protons in their nuclei, but differ only in the number of neutrons in the nuclei (e.g. carbon-12 has 6 protons and 6 neutrons, while carbon-14 also has 6 protons, but has 8 neutrons.
Why does the atomic number of an atom differ from the atomic mass?
Because the atomic number indicates the number of protons per nucleus while the mass number is the sum of the number of protons and the number of neutrons per nucleus, and all atoms except hydrogen-1 have neutrons in their nuclei.
When atoms of the some elements differ in the number of neutrons?
isotopes
Atoms of the same element that differ in number of neutrons?
isotopes
