What is the significance of Mendeleev's periodic table?
It was a system for organizing historical events
It was used to classify animals based on their habitats
It was a method for categorizing different types of rocks
It organized elements based on their properties and predicted the existence of undiscovered elements.
How are elements organized in the periodic table?
Based on their color and size
Based on their atomic number and chemical properties
Based on their melting point and boiling point
Based on their alphabetical order
What are the properties of elements in the same group or family?
Same physical properties
No relation in properties
Different chemical properties
Similar chemical properties
What is the relationship between the number of electron shells and periods in the periodic table?
The number of electron shells remains constant
The number of electron shells increases
The number of electron shells is unrelated to periods in the periodic table
The number of electron shells decreases
How do atomic size and electronegativity change across a period in the periodic table?
Atomic size decreases and electronegativity increases
Atomic size decreases and electronegativity remains constant
Atomic size increases and electronegativity decreases
Atomic size remains constant and electronegativity decreases
