Frequently asked questions
What is Topic P1: Matter?
OCR Matter: particle model, changes of state and pressure. 17 lessons in 3 subtopics.
What is the formula for density?
The density formula is ρ = m/V: density = mass ÷ volume, with mass in kilograms (kg), volume in cubic metres (m³) and density in kg/m³. The Calculating Density notes cover this in full.
What is an isotope?
Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. The Isotopes and Ion Formation notes cover this in full.
How do you find mass from density and volume?
Mass is found by rearranging the density equation to m = ρ × V. The Calculating Density notes cover this in full.
What are the units of density?
Density is measured in kg/m³ or g/cm³. The States of Matter and Density notes cover this in full.
What is the atomic number?
The atomic number is the number of protons in the nucleus of an atom, which defines the element. The Atomic Number, Mass Number, and Neutral Atoms notes cover this in full.
What is density?
Density is the mass per unit volume of a material, telling us how much matter is packed into a given space. The Calculating Density notes cover this in full.
What is the relative mass of an electron?
The relative mass of an electron is 1/1840, which is negligible, compared with 1 for a proton or neutron. The The Structure of the Atom notes cover this in full.
Who discovered the electron?
J.J. The Early Atomic Models notes cover this in full.
