Q1 Adv. Chemistry Recovery Learning Assignment

Front

What is the trend in ionization energy across a period in the periodic table?

Back

Ionization energy generally increases across a period from left to right due to increasing nuclear charge, which holds the electrons more tightly.

Front

What is the definition of significant figures?

Back

Significant figures are the digits in a number that contribute to its precision, including all non-zero digits, any zeros between significant digits, and trailing zeros in the decimal portion.

Front

What is the formula for calculating the volume of a rectangular prism?

Back

Volume = length × width × height.

Front

What is the atomic theory proposed by John Dalton?

Back

John Dalton's atomic theory states that matter is made of atoms, which are indivisible and cannot be created or destroyed.

Front

How do you convert cubic feet to cubic yards?

Back

To convert cubic feet to cubic yards, divide the volume in cubic feet by 27 (since 1 cubic yard = 27 cubic feet).

Front

What is the significance of the number of protons in an atom?

Back

The number of protons determines the atomic number of an element and defines the element's identity.

Front

What is the relationship between protons, neutrons, and electrons in a neutral atom?

Back

In a neutral atom, the number of protons equals the number of electrons, resulting in no overall charge.

Front

What is the concept of electron configuration?

Back

Electron configuration describes the distribution of electrons in an atom's orbitals, following the Aufbau principle, Pauli exclusion principle, and Hund's rule.

Front

What is the difference between an element and a compound?

Back

An element is a pure substance made of only one type of atom, while a compound is a substance formed when two or more different types of atoms bond together.

Front

What is the principle of conservation of mass?

Back

The principle of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.
