What does it mean if two atoms are isotopes?
If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.
What is beryllium mass number?
Beryllium Atomic number: 4 Atomic Mass: 9.012
What does a bigger atomic number mean?
A bigger atomic number indicates that the atom has more protons in its nucleus, which in turn determines its identity as an element. As the atomic number increases, the element becomes heavier and may have different properties due to the increasing number of protons and electrons.
How would the periodic table look different if it were arranged according to the atomic mass?
If the periodic table were arranged by atomic mass, some elements would be in a different order compared to the current arrangement by atomic number. This would mean elements with similar atomic masses would be grouped together, rather than by atomic number. The trends and patterns in the properties of elements might be less clear compared to the current layout based on atomic number.
What does it mean to say the atomic number in an atom?
The atomic number of an atom is the number of protons in its nucleus. It determines the element's identity on the periodic table and is used to arrange elements in ascending order based on their properties.
What does it mean if two atoms are isotopes?
If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.
What is rubidiums atomic number and what those it mean?
atomic number is 37
Can an atom of two different elements have the same mass number?
Yes. The mass number is basic to the different elements, even more useful than the atomic number. (Unless it is an isotope. Isotopes have a different amount of neutrons than the basic element atom which makes a difference in mass number too. So, a difference in mass numbers doesn't always mean it is a different element.)
What is beryllium mass number?
Beryllium Atomic number: 4 Atomic Mass: 9.012
Idotopes of the same element have different?
if you mean isotopes then isotopes of the same element have a different number of neutrons in the nucleus so have a different atomic weight.
Gold has an atomic number of 79 What does the 79 mean?
The atomic number is the number of protons in the nucleus of the atom.
What does the atomic number for californium mean?
The meaning of the atomic number is: number of protons and electrons (for californium is 98).
What subatomic particle gives you the atomic number?
Protons.The atomic number of an atom is the number of protons in the atom. The identity of an atom is based on its atomic number, so a change in the number of protons mean an atom has turned into a different element. However, an addition or subtraction of neutrons creates different isotopes of an element, and a change in the number of electrons creates an ion of the element.
What does a bigger atomic number mean?
A bigger atomic number indicates that the atom has more protons in its nucleus, which in turn determines its identity as an element. As the atomic number increases, the element becomes heavier and may have different properties due to the increasing number of protons and electrons.
How is the element with atomic number 82 in the periodic table different from the element in the atomic number 81?
The atomic number the the number of protons and therefore the total positive charge in the nucleus. So the the element with the atomic number 82 has more protons and a greater nuclear charge then the atomic number of 81. More protons can mean many different things such as a smaller radius, greater first ionisation energy or greater electronegativity.
What do you mean by atomic number?
Atomic number = Number of protons = Number of electrons (in the neutral state) Also the atomic number is number of a chemical element in the periodic table of Mendeleev.
How would the periodic table look different if it were arranged according to the atomic mass?
If the periodic table were arranged by atomic mass, some elements would be in a different order compared to the current arrangement by atomic number. This would mean elements with similar atomic masses would be grouped together, rather than by atomic number. The trends and patterns in the properties of elements might be less clear compared to the current layout based on atomic number.
