Electrons group themselves in pairs in their energy levels. To calculate the number of electrons allowed in any energy level, find the square of the number representing the energy level and multiply it by two. Using this formula, atoms can have two electrons in their first energy level, eight in the second, and eighteen in their third. The quantity of electrons at each level grows as the number of the energy level increases.
Foliated metamorphic rocks such as gneiss, Phyllis, schist, and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure. Non-foliated metamorphic rocks such as hornfels, marble, quartzite, and novaculite do not have a layered or banded appearance.
Answer:
The answer is 1722 e⁻
Explanation:
Let's make a rule of three:
9.708×10⁻³¹ kg is the mass of 1 e⁻
1.672 ×10⁻²⁷ kg (which is 1 p⁺), how many e⁻ does it contain.?
1.672 ×10⁻²⁷ kg / 9.708×10⁻³¹ kg
The answer is 1722 e⁻
Answer: i have not 1 idea
Explanation:
Answer:
kinetic energy.
Explanation:
an object in motion collides with another object to make that object in motion.
kinetic energy is the energy of an object being in motion.
