Chemistry flashcards for ICSE Class 10
21 of 51 cards from the Chemistry deck — real questions with worked answers.
What is the modern periodic law?
The physical and chemical properties of elements are a periodic function of their atomic numbers.
How many periods and groups are there in the modern (long form) periodic table?
7 periods (horizontal rows) and 18 groups (vertical columns).
On what basis did Mendeleev arrange elements in his periodic table?
In order of increasing atomic mass (and similar properties placed in the same group).
What does the period number of an element indicate?
The number of shells (energy levels) in the atom.
What does the group number (for normal/representative elements) indicate?
The number of valence electrons (electrons in the outermost shell).
How does atomic size (radius) vary across a period from left to right?
It decreases, because nuclear charge increases while electrons are added to the same shell, pulling them closer.
How does atomic size vary down a group?
It increases, because the number of shells increases.
How does metallic character vary across a period and down a group?
It decreases across a period (left to right) and increases down a group.
How does ionisation energy (potential) vary across a period and down a group?
It increases across a period (left to right) and decreases down a group.
How does electron affinity generally vary across a period and down a group?
It increases across a period (left to right) and decreases down a group.
How does electronegativity vary across a period and down a group?
It increases across a period (left to right) and decreases down a group.
Which is the most electronegative element, and which is the most metallic (electropositive) in the periodic table?
Fluorine is the most electronegative; caesium (francium) is the most metallic/electropositive.
What are the alkali metals and which group do they belong to?
Group 1 elements (Li, Na, K, Rb, Cs, Fr) — highly reactive metals with 1 valence electron.
What are the halogens and which group do they belong to?
Group 17 elements (F, Cl, Br, I, At) — reactive non-metals with 7 valence electrons.
Why are noble gases (Group 18) chemically inert?
They have a complete, stable outermost shell (duplet for He, octet for the rest), so they have no tendency to gain, lose, or share electrons.
What is a chemical bond?
The force of attraction that holds atoms together in a molecule or compound, formed to attain a stable noble-gas (octet/duplet) electron configuration.
What is an electrovalent (ionic) bond?
A bond formed by the complete transfer of one or more electrons from a metal atom to a non-metal atom, producing oppositely charged ions held by electrostatic attraction.
What is a covalent bond?
A bond formed by the mutual sharing of one or more pairs of electrons between two atoms (usually non-metals).
What is a coordinate (dative) bond?
A covalent bond in which the shared pair of electrons is contributed by only one of the two atoms (the donor); the other atom (acceptor) only shares it.
Give one example each of a compound with a single, double, and triple covalent bond.
Single: H2 (or Cl2); Double: O2 (or CO2); Triple: N2.
List three examples of compounds containing a coordinate bond.
Ammonium ion (NH4+), hydronium ion (H3O+), and ozone (O3) (also Al2Cl6).
Planning Chemistry for ICSE Class 10
Chemistry is about 9% of the ICSE Class 10 syllabus by topic count — 5 of 53 topics, spread over 1 chapters. At roughly 45 minutes per topic plus 12 minutes per sub-topic, a first pass runs to about 4 hours.
Work top-down: read the chapter, then tick topics off individually rather than marking the whole chapter done. Sub-topics are where silent gaps hide.
