Is an electron just a name for both neutrons and protons?
No, electrons are different from neutrons and protons. Electrons have a negative charge and orbit the atomic nucleus where protons and neutrons are found. Protons have a positive charge and neutrons have no charge.
Is there anything smaller than an atom?
Atoms are considered the smallest unit of matter, made up of protons, neutrons, and electrons. Subatomic particles like quarks and leptons make up protons, neutrons, and electrons, but are not considered smaller than an atom.
Which best describes an atom of carbon-13?
An atom of carbon with 6 protons and 7 neutrons.
How many protons and neutrons does radium have?
88
What particle make up the nucleus of an atom?
protons and neutrons
Is an electron just a name for both neutrons and protons?
No, electrons are different from neutrons and protons. Electrons have a negative charge and orbit the atomic nucleus where protons and neutrons are found. Protons have a positive charge and neutrons have no charge.
What is best described as an atom?
A core of protons and neutrons surronded by electrons.
Which best describes the relationship between subatomic particles in any neutral atom?
Neutrons and protons are found in the nucleus of the atom, while electrons orbit around the nucleus in specific energy levels. The number of protons in the nucleus determines the atom's identity, while the number of neutrons helps determine its isotope.
Did Mendeleev know about protons neutrons and electrons?
No, Mendeleev did not know about protons, neutrons, and electrons. He is best known for creating the periodic table of elements based on the properties of the elements without knowledge of the atomic structure. The discovery of protons, neutrons, and electrons came later with the development of atomic theory.

Which best describes an atom of carbon-13?
An atom of carbon with 6 protons and 7 neutrons.
The sum of the protons and the neutrons will tell the atomic what?
Atomic mass number of the atom. The best way to remember it is: the majority of the mass of an atom is made up of the protons and neutrons (the electrons are very light!), therefore the atomic mass number is the sum of the protons and neutrons.
What best describes the nucleus of atom?
Nucleus is the centre of an atom and consists of positively charged protons and neutral neutrons.
Which best describes the nucleus of an atom?
The nucleus of an atom is the densest part of an atom. It contains the protons and neutrons of an atom.
What term best describes the sum of the number of protons and neutrons in an atom?
Atomic mass or mass number.
What is the best description of how an atom is organized?
An atom is organized with a nucleus at its center, containing protons and neutrons. Electrons orbit the nucleus in specific energy levels or shells. The nucleus is positively charged, while electrons are negatively charged, creating a stable, neutral atom.
How many protons and neutrons does radium have?
