What else can I help you with?
Atom does not have to have equal numbers of protons and?
neutrons in order to be stable. The number of protons determines the element's identity, while the stability of the nucleus is influenced by the balance of protons and neutrons. Isotopes can have different numbers of neutrons while maintaining the same number of protons.
Are there the same number of portons and neutrons in an atom?
No, atoms do not always have the same number of protons and neutrons. The number of protons determines the element, while the sum of protons and neutrons determines the isotope of an element. Some atoms have equal numbers of protons and neutrons, but others have different numbers.
What do isotopes and nucleus have in common?
Isotopes and nuclei are both related to atoms. Isotopes are atoms of the same element with different numbers of neutrons in their nuclei. The nucleus is the central part of an atom that contains protons and neutrons.
An isotope is identified by its atomic mass number which is the total number of?
protons and neutrons in the nucleus of an atom. Isotopes of an element have the same number of protons but different numbers of neutrons. The number of neutrons in an atom affects its stability and often determines its nuclear properties.
What kind of particle have a unequal number of protons and neutrons?
An isotope is a particle that has an unequal number of protons and neutrons. Isotopes of an element have the same number of protons but different numbers of neutrons. These variations in the number of neutrons result in different atomic masses for isotopes of the same element.
Atom does not have to have equal numbers of protons and?
neutrons in order to be stable. The number of protons determines the element's identity, while the stability of the nucleus is influenced by the balance of protons and neutrons. Isotopes can have different numbers of neutrons while maintaining the same number of protons.
How is isotope and mass number related?
2 isotopes of the same element will have the same number of protons but a different number of neutrons. The sum of protons and neutrons is the mass number, so different isotopes will have different mass numbers.
Are there the same number of portons and neutrons in an atom?
No, atoms do not always have the same number of protons and neutrons. The number of protons determines the element, while the sum of protons and neutrons determines the isotope of an element. Some atoms have equal numbers of protons and neutrons, but others have different numbers.
What are the different numbers of neutrons called when two atoms have the same number of protons?
Two atoms with the same number of protons but different numbers of neutrons are called "isotopes".
What is the mass number of an isotopes that has 5 protons 6 neutrons and selectrons?
The atomic number is the number of protons. The atomic mass number is the the sum of the numbers of neutrons and protons combined, in this instance, 11.
What is the sum of the numbers of protons in the neutrons in the nucleus?
The mass number.
How do the numbers of protons neutrons and electrons for an element compare?
Protons and electrons have the same number in a neutral atom. Neutrons can vary in number for an element, creating different isotopes. The atomic number equals the number of protons, the mass number equals the sum of protons and neutrons.
How is the mass number related to the number of protons and neutrons and atoms has?
The mass number of an atom is the sum of its protons and neutrons. It represents the total number of nuclear particles (protons and neutrons) in the atom's nucleus. The number of protons in an atom determines its element, while the number of neutrons can vary to create different isotopes of the element.
How is the nucleus related to the periodic table?
The nucleus contains the protons and neutrons. The number of protons determines the atomic number of the element and the number of protons and the number of neutrons together determine the atomic mass.
What is the name given to atoms of the same element that have the same number of protons?
Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.
What do isotopes and nucleus have in common?
Isotopes and nuclei are both related to atoms. Isotopes are atoms of the same element with different numbers of neutrons in their nuclei. The nucleus is the central part of an atom that contains protons and neutrons.
What are atoms containing the same numbers of protons and different numbers of neutrons are?
Atoms containing the same number of protons but different numbers of neutrons are called isotopes. Isotopes have the same atomic number (number of protons) but differ in atomic mass due to the varying number of neutrons.
