, CSP1501 ASSIGNMENT 03 SEMESTER 01 2026 - DUE DATE : 10 APRIL 2026 : UNIQUE NO: 586160
QUESTION 1
1. Differences Between the Physical Properties of Metals and Nonmetals
Metals Nonmetals
Shiny (lustrous) Dull (non-lustrous)
Good conductors of heat and electricity Poor conductors of heat and electricity
Malleable (can be hammered into thin sheets) Brittle (break easily, not malleable)
Ductile (can be drawn into wires) Not ductile
High density Low density
High melting and boiling points Low melting and boiling points
Mostly solid at room temperature (except Can be solid, liquid, or gas at room
mercury) temperature
Strong and hard Usually soft and weak
Sonorous (make a ringing sound when struck) Not sonorous
Expand more when heated Expand less when heated
2: EXPLORING THE PERIODIC TABLE AND THE PROPERTIES OF ELEMENTS
2.1 An aluminum atom has 13 electrons, 13 protons, and 14 neutrons.
2.2 There are 18 element groups in the periodic table.
2.3 Hydrogen belongs to Group 1 (the alkali metals group).
