Which of the following correctly compares the phosphorus isotopes?
Which of the following correctly compares the phosphorus isotopes?
Answers. The statement that correctly compares the phosphorus isotopes 31p and 32p is 31 p has 16 neutrons whereas 32 p has 17 neutrons. isotopes are atoms of the same element that have the same atomic number or the number of protons but different mass number.
What two atoms are isotopes of the same element?
1 Basic principles. Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.
What are atoms with nuclei that contain the same number of protons but a different number of neutrons called?
Two atoms with the same atomic number, but different mass numbers (same number of protons, different number of neutrons), are called isotopes, or isotopic nuclides. Having different numbers of neutrons changes the mass of these atoms, so isotopes have slight variations in their physical and chemical behavior.
Which two nuclei contain the same number of neutrons?
Atoms of the same element that contain the same number of protons, but different numbers of neutrons, are known as isotopes. Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2).
What is the name of an atom with 2 protons and 4 neutrons?
element helium
What is Carbon’s number of neutrons?
6 neutrons
What is atomic number in simple words?
Atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number.
What is the definition of nucleons?
1 : a proton or neutron especially in the atomic nucleus. 2 : a hypothetical single entity with one-half unit of isospin that can manifest itself as either a proton or a neutron.
Why is atomic number important?
The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.6 hari yang lalu
