Doberiner's quartets stated that elements 2 and 3 have properties halfway between elements 1 and 4.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Doberiner's quartets did not state that elements 2 and 3 have properties halfway between elements 1 and 4. Instead, it proposed that elements 1 and 4 have similar properties, while elements 2 and 3 have properties that are different from both 1 and 4. This concept was later refined and expanded upon by Mendeleev in the development of the periodic table.Rate this question:

Germanium has a higher metallic character then sodium.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Germanium does not have a higher metallic character than sodium. Metallic character refers to the ability of an element to exhibit metallic properties such as being malleable, ductile, and having a high electrical conductivity. Sodium is a highly reactive metal with a low melting point and is commonly found in its metallic form. Germanium, on the other hand, is a metalloid that exhibits both metallic and non-metallic properties. While it can conduct electricity, it is brittle and has a higher melting point compared to sodium. Therefore, the statement is false.Rate this question:

Period 6 elements have a lower ionization energy than period 2 elements.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Period 6 elements have a lower ionization energy than period 2 elements because as you move down a periodic table, the atomic radius increases. This means that the outermost electrons in period 6 elements are further away from the nucleus and experience less attraction, making it easier to remove them. In contrast, period 2 elements have smaller atomic radii, resulting in stronger attraction between the nucleus and outermost electrons, requiring more energy to remove them. Therefore, period 6 elements have lower ionization energies compared to period 2 elements.Rate this question:

What is the main thing Mendeleev knowingly based the order of his periodic table on, causing him to order it like no one else had done before?
- A.
Atomic number
- B.
Chemical properties
- C.
Physical properties
- D.
Atomic mass
Correct Answer
B. Chemical propertiesExplanation
Mendeleev knowingly based the order of his periodic table on chemical properties. He arranged the elements according to their similar chemical properties, which allowed him to group elements with similar behaviors together. This arrangement was unique and different from any previous attempts at organizing the elements. Mendeleev's periodic table became the foundation for the modern periodic table we use today.Rate this question:

What did Mosley use to determine the atomic number of the elements?
- A.
An electron microscope
- B.
An electron balance
- C.
A compilation of data from other scientists
- D.
X-Rays
Correct Answer
D. X-RaysExplanation
Mosley used X-Rays to determine the atomic number of the elements. X-rays have the ability to penetrate materials and interact with the electrons in an atom. By studying the X-ray spectra produced by different elements, Mosley was able to identify patterns and correlations between the spectra and the atomic number. This led to the discovery of the relationship between the atomic number and the number of protons in the nucleus, which is now known as the basis of the modern periodic table.Rate this question:

The element with the configuration [Ar] 4s2 3d10 4p1 is located in which period and group?
- A.
Period 6 No Group
- B.
Period 4 Group 13
- C.
Period 2 Group 2
- D.
No period Group 14
Correct Answer
B. Period 4 Group 13Explanation
The element with the electron configuration [Ar] 4s2 3d10 4p1 belongs to period 4 because the highest energy level (valence shell) is the fourth energy level. It belongs to group 13 because it has one valence electron in the p orbital, which corresponds to group 13 on the periodic table.Rate this question:

What can be defined as "The energy change that occurs when an atom gains an electron to form an ion?"
- A.
Ionization energy
- B.
Ionic radii
- C.
Electron affinity
- D.
Metallic character
Correct Answer
C. Electron affinityExplanation
Electron affinity refers to the energy change that occurs when an atom gains an electron to form an ion. It quantifies the attraction between an atom and an additional electron. When an atom gains an electron, energy is released, resulting in a negative electron affinity value. This process is important in understanding the reactivity and chemical behavior of elements, as it helps determine the likelihood of an atom gaining an electron to form an ion.Rate this question:

Which of the following is true about atomic radii?
- A.
It increase from left to right across a period
- B.
It increases as you go down a group
- C.
It is one-fourth the distance between the nuclei of identical bonded atoms
- D.
It decrease from left to right across a period
Correct Answer
B. It increases as you go down a groupExplanation
The atomic radii refers to the size of an atom. As you move down a group in the periodic table, the number of energy levels or shells increases. This results in an increase in atomic size because there are more electrons and a greater distance between the nucleus and the outermost energy level. Therefore, the statement "It increases as you go down a group" is true.Rate this question:

The elements in which block(s) are known as the main group elements?
- A.
D and f
- B.
S and d
- C.
P and s
- D.
D only
Correct Answer
C. P and sExplanation
The main group elements in the periodic table are located in the s and p blocks. These blocks consist of the elements in the first two columns (Group 1 and 2) and the last six columns (Group 13 to 18). The s block contains elements with their outermost electron in the s orbital, while the p block contains elements with their outermost electron in the p orbital. Therefore, the correct answer is p and s.Rate this question:
