Electronegativty is what determines how an atom would bond and its need to form a stable octet.
J.J. Thomson hypothesized and discovered that the atom was not the smallest unit of matter but that instead there were much smaller units. He discovered "sub-atomic particles" which make up atoms. The sub-atomic particle that Thomson discovered was the electron. He discovered this through a process of experiments testing cathode rays.
1.81 x 10²⁴particles of Fe
Explanation:
Given parameters:
Number of moles = 3moles
Unknown:
Number of particles = ?
Solution:
The number of particles in a substance can be deduced from the relationship of number of moles with the Avogadro's number.
A mole of a substance is the quantity of substance that contains the Avogadro's number of particles.
1 mole = 6.02 x 10²³ particles
3 moles = 3 x 6.02 x 10²³ = 1.81 x 10²⁴particles of Fe

Explanation:
Answer:
Explanation:
Quantity of copper measured by a student = 4.6 grams
Original quantity of copper = 4.7 grams
Error in measurement = Original quantity of copper - Quantity of copper measured by a student grams
To find the percent error, apply the following formula:
Percent error = (Error in measurement / Original quantity of copper) × 100
