How does the arrangement of elements in periods relate to electron configuration

1 answer:

4 0

Electronic Configuration of elements in a period is same because If you see the electronic Configuration of elements in a period you will notice that the valence shell electrons for all elements are present in the same Shell. For example, in first period consisting of Hydrogen and Helium, both the elements' valence electrons are present in the same Shell.
Electronic Configuration of Hydrogen,
1s^1
Electronic Configuration of Helium,
1s^2

Both elements' valance electrons are present in the 1st shell

(This is just a small example to understand the concept because other periods are long but the first period is short that's why I gave the example of the first period)

A crow flies 100 meters east in 5 minutes. What is the crow’s velocity?

torisob [31]

Answer: 20 m/min east

Explanation: The speed is distance divided by time

distance between start-point and end-point = 100 meters

time to cover the distance = 5 minutes

100 m ÷ 5 min = 20 m/min east

you have to add east since velocity is the measure of speed and direction and your answer needs to include the direction

How are sound waves and EM waves alike? How are they different?

Hatshy [7]

Sound waves are longitudinal waves that is, are transmitted in the same direction of oscillation of the particles in the medium. Electromagnetic waves are transverse ie, the electric and magnetic fields, which are perpendicular to each other, oscillate perpendicularly to the direction of wave propagation.

An airplane model is an example of what type of model

Ksju [112]

TL;DR: The make of an aircraft is the name of the designer (for example, Boeing) and the model of an aircraft (also called the type) is the designation for the general design of the aircraft (for example, 737). It looks like "basic model" is just an older term for "model".
