KPK 9th Class Chemistry Chapter 3 Periodic Table & periodicity of Properties Short Questions Answers
Which element of group IA is not alkali metal and why?
Group IA is consisted of following elements.
Element Metallic nature
H Non-metal
Li Metal
Na Metal
K Metal
Rb Metal
Cs Metal
Fr Metal
All are metallic solids except H- gas, which is non-metal.
It has totally different physical behavior from alkali metals.
Place the following elements in order of increasing I.E, Na, s, Mg and Ar
Given elements are the members of same period.
Their increasing order of I.E is given below.
Na<Mg<S<Ar
Name the group and state the group number of each of the following elements.<br /> K, Ne, Be, Cl, C.
Ans: Name and of each given element is listed below.
Element Group Name Group No
K Alkali Metals IA
Ne Noble Gases VIIIA
Be Alkaline Earth Metals VIIA
Cl Halogens VIIA
C Carbon Family IVA
Which element is the most electronegative among C,N,Br,&S? Which group does it belongs too?
Oxygen of the given one is most electronegative element. It belongs to VIAgroup
How do the 1st I.E of representative elements vary across a period and down a group?
1st I.E of representive elements (S-Block & P-Block) increases from left to right and decreases GroupWise.
Which element found in,<br /> a) Period 2 and group VII<br /> b) Period 4 and group III<br /> c) Period 5 and group VI<br /> d) Period 1 and group VII
| Location | Element |
| a) Period 2 and group VII | F |
| b) Period 4 and group III | Ga |
| c) Period 5 and groupVI | Te |
| d) Period 1 and group VIII | He |
How differentiate between respresentative and transition elements?
1. These are the elements of s-block and p-bloch of periodic table.
2. They generally have valence electrons either in s or p-sub shall.
3. Their valence electronic con figuration is ns1-2& np1-6
Transition Elements
1. These are the elementsof d-block and f-block of periodic table.
2. They generally have incomplete d or f- sub shell.
3. They have generally variable valency.
Make a general sketch of periodic table.Showing s,p,d and f-block elements.
why the s-block elements have groups only?
S- sub shell can maximum hold 2 en.Therefore there exist just two series of s- block elements as,
Elements with ns1 electronic configuration (alkali metals)
Elements with ns2 electronic configuration (alkaline earth metals).
What type of element is sulpher? A respresentative, transition or lanthanide element?
Sulpher is a respresentative element. It is a member of p-block elements, exist in 3rd period and VIA group.
How to Write Perfect Short Answers?
In Board Exams, the examiner looks for specific keywords and presentation. Here is how to attempt Chapter 3 questions:
- Ideal Length: Write 3 to 5 lines for each short question. Too short gets fewer marks, too long wastes time.
- Highlighting: Use a Blue Marker to highlight key dates, names, or scientific terms in your answer.
- Units & Formulas: Always write the formula and SI unit. Without units, 0.5 marks are deducted.
