Quiz For The Lesson On Atomic Structure And The Periodic Table
-
Another name for the columns of a periodic table is
-
Period
-
Group
-
Isles
-
Clusters
-
Atoms are indivisible though it defines the size and mass of any element. Atomic structure and number defines the volume of an element and this helps us identify solids from liquids based on their atomic sizes. Are you interested in understanding atomic structure give the quiz a try and do that.

Atoms of an element that have different numbers of neutrons
-
Radioactive
-
Quarks
-
Isotopes
-
Protons
Correct Answer
A. IsotopesExplanation
Isotopes are atoms of an element that have different numbers of neutrons. Neutrons are subatomic particles found in the nucleus of an atom and they do not have an electric charge. Isotopes of an element have the same number of protons, which determines the element's identity, but they differ in the number of neutrons. This difference in the number of neutrons results in different atomic masses for isotopes of the same element. Some isotopes can be radioactive, meaning they are unstable and undergo radioactive decay, emitting radiation in the process.Rate this question:

Another name for the group in which argon is found is
-
Halogens
-
Alkaline
-
Transition
-
Noble gases
Correct Answer
A. Noble gasesExplanation
Argon belongs to the group of elements known as noble gases. Noble gases are characterized by their low reactivity and full outer electron shells, making them stable and non-reactive. Other elements in this group include helium, neon, krypton, xenon, and radon. Therefore, the correct answer is noble gases.Rate this question:

The horizontal rows of the periodic table
-
Periods
-
Family
-
Groups
Correct Answer
A. PeriodsExplanation
The horizontal rows of the periodic table are called periods. Each period represents a specific energy level or shell in which the electrons of the elements reside. As you move from left to right across a period, the number of electrons and their energy increases. The periodic table is organized in this way to show the trends in properties and characteristics of elements as you move across the periods. Therefore, the correct answer is "periods".Rate this question:

Elements found genrally on the left of the periodic table are;
-
Non-metal
-
Metals
-
Metalloids
Correct Answer
A. MetalsExplanation
Metals are generally found on the left side of the periodic table. They are characterized by their luster, conductivity, and malleability. These elements tend to lose electrons easily and form positive ions. They are good conductors of heat and electricity and are typically solid at room temperature (except for mercury). Examples of metals include copper, iron, and gold.Rate this question:

The region around the nucleus of an atom is called the
-
Proton
-
Electron clouds
-
Isotopes
-
Neutrons
Correct Answer
A. Electron cloudsExplanation
The region around the nucleus of an atom is called the electron clouds because it is where the electrons are most likely to be found. Electrons are negatively charged particles that orbit the nucleus in specific energy levels or shells. These shells form a cloud-like region around the nucleus, and the electrons within them move rapidly and unpredictably. The electron clouds determine the chemical properties and behavior of an atom, as they are involved in bonding and interactions with other atoms.Rate this question:

Another name for the elements of the flourine family
-
Alkali
-
Alkaline
-
Noble
-
Halogens
Correct Answer
A. HalogensExplanation
The correct answer is "halogens" because the elements in the fluorine family belong to Group 17 of the periodic table, which is known as the halogens. This group includes elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive nonmetals that readily form compounds with other elements. They have seven valence electrons and tend to gain one electron to achieve a stable electron configuration. Therefore, "halogens" is the appropriate term to describe the elements in the fluorine family.Rate this question:

One of the two particles that make up the atomic mass of an element is
-
The electron
-
Neutron
-
Silicon
-
Partrons
Correct Answer
A. NeutronExplanation
The correct answer is neutron. Neutrons are subatomic particles that are found in the nucleus of an atom. They have a neutral charge and contribute to the atomic mass of an element along with protons. Electrons, on the other hand, have a negative charge and are found in the electron cloud surrounding the nucleus. Silicon is an element itself, not a particle that makes up atomic mass. "Partrons" is not a recognized term in the context of atomic structure.Rate this question:
