Answer:
because only two electrons can fit in the first orbit around the nucleus, and each period on the table is organized by number of orbits
Answer:
The most common oxidation numbers for a given element
Answer:
q = 3.6 10⁵ C
Explanation:
To solve this exercise, let's use one of the consequences of Gauss's law, that all the charge on a body can be considered at its center, therefore we calculate the electric field on the surface of a sphere with the radius of the Earth
r = 6 , 37 106 m
E = k q / r²
q = E r² / k
q = 
q = 4.5 10⁵ C
Now let's calculate the charge on the planet with E = 222 N / c and radius
r = 0.6 r_ Earth
r = 0.6 6.37 10⁶ = 3.822 10⁶ m
E = k q / r²
q = E r² / k
q = 
q = 3.6 10⁵ C
Answer:
b im pretty sure (let me know if this is correct!) :)
Explanation:
The cost of electricity be $ 38.544.
<h3>What is electricity?</h3>
Electricity is the passage of charges in a conductor. From one end of the terminal to the other, charges are transmitted. Usually, the terminal moves from positive to negative. Since the nucleus holds the electrons loosely, they can move freely throughout the body.
Watts are units of power used to measure electrical output.
Price of electricity is $ 0.110 per kWh .
If a 40-W porch light on day and night for a year, total amount of electricity spend = power of the bulb × time
= 40 W × 1 year
= 40 W × 365 day
= 40 W × 365 ×24 h
= 350400 Wh
= 350.4 kWh.
Hence, the cost of electricity be = $350.4 × 0.110 = $ 38.544.
