Are atoms of the same elements with different number of neutrons in their nuclei?
Atoms of an element that contain different numbers of neutrons are called isotopes. Each isotope of a given element has the same atomic number but a different mass number (A), which is the sum of the numbers of protons and neutrons.
What is an atom of the same element with more or less neutrons called?
Atoms of a given element (atomic number) may have differing numbers of neutrons. Atoms of the same element with different mass numbers are known as isotopes. The mass numbers or isotopes of an element are denoted as preceding superscripts.
What is an atom with a different number of neutrons and electrons called?
isotopes
Such atoms are called isotopes of each other.
How are atoms of the same element similar and different?
ISOTOPES AND ATOMIC MASSES For many of the chemical elements there are several known isotopes. Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.
How do atoms of same element differ?
The element of an atom is decided by the number of protons (which is the same as the number of electrons) in the atom. Atoms of the same element can differ in their mass which is the case if the number of neutrons in the atoms is not the same. These atoms with different mass are called isotopes.
How many atoms of the same element differ They may have different?
Two atoms
Two atoms of the same chemical element are typically not identical. First of all, there is a range of possible states that the electrons of an atom can occupy. Two atoms of the same element can be different if their electrons are in different states.
What is it called when an atom has a different number of protons and electrons?
These are called isotopes of the element. Atoms of the same element have the same number of protons, which is called the atomic number. Different isotopes of an element have different numbers of neutrons. As a result, they also have different mass numbers, which is the number of protons plus the number of neutrons.
What makes atoms of different elements different?
The number of protons in an atom is the defining feature of an atom. It’s what makes one element different from another. The number of protons in an atom is called its atomic number. All the elements in the universe are arranged according to their atomic number in the periodic table.
Can atoms of different elements have the same atomic number?
All atoms of a chemical element have the same atomic number (number of protons in the nucleus) but may have different mass numbers (from having different numbers of neutrons in the nucleus).
What refers to atoms of the same element with the same number of protons but different number of neutrons?
Isotopes. An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.
What do you call the atoms of the same element but different in structure?
Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.
