From the information provided in the question, we can see that; the electron moved up to an energy level and has an energy of 21.72 x 10-19 J.
Bohr's model of the atom tells us that electrons are found in certain specific energy levels. Energy is absorbed when an electron moves from a lower to a higher energy level and energy is released when an electron moves from a higher to a lower energy level.
Given that;
ΔE = E2 - E1
E2 = final energy level
E1 = initial energy level
E2 = ?
E1 = 16.32 x 10-19 J
ΔE = 5.4 x 10-19
E2 = ΔE + E1
E2 = 5.4 x 10-19 + 16.32 x 10-19 J
E2 = 21.72 x 10-19 J

Answer:
The shaded area 2 is likely to have subatomic particle that are constantly in motion. I took the test and I got it right
Answer:
Plants, like all living things, need food to survive. Plants make their food using a process called photosynthesis, which means “putting together through light.” During photosynthesis, a plant traps energy from sunlight with its leaves. It also takes up water from its roots and carbon dioxide gas from the air.
Explanation:
Soil is made out of all of these things and covers almost all landmasses. Even below sand and rock there is soil.
Answer:
True
Explanation:
Gravity alone holds us to Earth's surface. Planets have measurable properties, such as size, mass, density, and composition. A planet's size and mass determines its gravitational pull.
