-0.372 g/cm3
-2.69 g/cm3
-4.24 g/cm3
Density = 2.69 g.cm⁻³
Data Given;
Density = ??
Mass = 37.1 g
Volume = 2.0 cm × 5.5 cm × 1.25 cm = 13.75 cm³
Formula Used;
Density = Mass ÷ Volume
Putting values,
Density = 37.1 g ÷ 13.75 cm³
Density = 2.69 g.cm⁻³
B) shifts to a more electronegative atom.
C) increases its kinetic energy.
D) increases its activity as an oxidizing agent.
E) moves further away from the nucleus of the atom.
An electron loses potential energy when it moves further away from the nucleus of the atom (option E).
As an electron moves to a higher energy level or shell, it is farther from the positive charge of the nucleus, resulting in a decrease in potential energy. Conversely, when an electron moves closer to the nucleus or shifts to a lower energy level, it gains potential energy. The movement of electrons within an atom influences various chemical and physical properties, including bonding, reactivity, and spectral behavior.
