Accepted Answer

### Question 1
# Brief Explanations:
A row in the periodic table is called a "period" (based on the repeating chemical properties as you move across) and also can be referred to as a "series" (relating to the electron shell filling order).
# Answer:
Two names of a row in the periodic table are: Period, Series

### Question 2
# Brief Explanations:
A column in the periodic table is called a "group" (elements in the same group have similar chemical properties) and also a "family" (since they share common characteristics like valence electron configuration).
# Answer:
Two names of a column in the periodic table are: Group, Family

### Question 3
# Brief Explanations:
Elements in the periodic table are arranged by increasing atomic number (the number of protons in the nucleus, which determines the element's identity) and historically was also related to atomic mass, but modern periodic table is ordered by atomic number.
# Answer:
Elements in the periodic table are arranged in order of increasing atomic number.

### Question 4
# Brief Explanations:
Elements in the same family (group) have the same number of valence electrons (electrons in the outermost shell). This similar valence electron configuration leads to similar chemical properties (like how they react with other elements, form bonds, etc.).
# Answer:
Elements in the same family have the same number of valence electrons (and thus similar chemical properties).

### Question 5
# Brief Explanations:
Metalloids are elements with properties between metals and non - metals. The metalloids are: Boron (B), Silicon (Si), Germanium (Ge), Arsenic (As), Antimony (Sb), Tellurium (Te), Polonium (Po), and sometimes Astatine (At) is also considered.
# Answer:
The metalloids are: Boron (B), Silicon (Si), Germanium (Ge), Arsenic (As), Antimony (Sb), Tellurium (Te), Polonium (Po) (and sometimes Astatine (At)).

### Question 6
# Brief Explanations:
Noble gases are in group 18. They have a full valence electron shell (octet, except Helium which has a duet). A full valence shell means they have little tendency to gain or lose electrons, so they are very stable and unreactive under normal conditions.
# Answer:
Noble gases are the most stable because they have a full valence electron shell (octet/duet), so they have no tendency to gain or lose electrons (are unreactive).

### Question 7
# Brief Explanations:
The d - block elements in the periodic table are called transition metals. These elements have partially filled d - orbitals (or can form ions with partially filled d - orbitals) and show typical metallic properties like malleability, ductility, good conductivity, and also show variable oxidation states and form colored compounds.
# Answer:
d - block elements are called transition metals.

### Question 8
# Brief Explanations:
The f - block elements are called inner transition metals. They are further divided into lanthanides (elements 58 - 71, related to Lanthanum) and actinides (elements 90 - 103, related to Actinium). These elements have partially filled f - orbitals.
# Answer:
f - block elements are called inner transition metals (lanthanides and actinides).

### Question 9
# Brief Explanations:
- a. Group 18: Group 18 elements are called noble gases (or inert gases). They are Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), Radon (Rn), and Oganesson (Og).
- b. Group 1: Group 1 elements are called alkali metals. They include Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), Francium (Fr).
- c. Group 7: Group 7 elements are called halogens. They are Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I), Astatine (At), Tennessine (Ts).
- d. Group 2: Group 2 elements are called alkaline earth metals. They are Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), Radium (Ra).
# Answer:
- a. Group 18: Noble Gases
- b. Group 1: Alkali Metals
- c. Group 7: Halogens
- d. Group 2: Alkaline Earth Metals

### Question 10
# Brief Explanations:
- a. Sulfur (S): Group 16 (Chalcogens), Non - metal.
- b. Nitrogen (N): Group 15 (Pnictogens), Non - metal.
- c. Arsenic (As): Group 15, Metalloid.
- d. Copper (Cu): Group 11 (Transition Metals), Metal.
- e. Chlorine (Cl): Group 17 (Halogens), Non - metal.
- f. Boron (B): Group 13, Metalloid.
- g. Sodium (Na): Group 1 (Alkali Metals), Metal.
- h. Calcium (Ca): Group 2 (Alkaline Earth Metals), Metal.
# Answer:
- a. Sulfur: Group 16 (Chalcogens), Non - metal
- b. Nitrogen: Group 15 (Pnictogens), Non - metal
- c. Arsenic: Group 15, Metalloid
- d. Copper: Group 11 (Transition Metals), Metal
- e. Chlorine: Group 17 (Halogens), Non - metal
- f. Boron: Group 13, Metalloid
- g. Sodium: Group 1 (Alkali Metals), Metal
- h. Calcium: Group 2 (Alkaline Earth Metals), Metal

### Question 11
# Brief Explanations:
Period 6 is the 6th row of the periodic table. Looking at the metalloids in period 6, Polonium (Po) is in period 6 and is a metalloid.
# Answer:
The element in period 6 and is a metalloid is Polonium (Po).
