WebFeb 3, 2024 · The probability of finding an electron in the conduction band is shown by the equation: (6.8B.1) P = 1 e Δ E / R T + 1. The ∆E in the equation stands for the change in energy or energy gap. t stands for the temperature, and R is a bonding constant. That equation and this table below show how the bigger difference in energy is, or gap ... WebAdvantages: Bronze is an alloy consisting mainly of copper but the addition of other metals (usually tin) produces an alloy much harder than plain copper. Bronze resists corrosion and metal fatigue better, and conducts heat and electricity, better than most steels. Disadvantages: Bronzes are generally softer, weaker and more expensive than steel.
