The view about electronic components on online

This is a view on online about electronic component,as long as there is electronic
product exists not without the electronic components.
An electronic component is a basic electronic element usually packaged in a discrete
form with two or more connecting leads or metallic pads. Ic components are intended to be
connected together, usually by soldering to a printed circuit board, to create an
electronic circuit with a particular function (for example an amplifier, radio
receiver, or oscillator). Components may be packaged singly (resistor, capacitor,
transistor, diode etc.) or in more or less complex groups as integrated circuits
(operational amplifier, resistor array, logic gate etc.)

Who can tell me the question about electronic component

Hi hope someone could help me understand the workings of electronic components.

I think I am right in saying that all electronic components require energy for them to function.

If you connect a battery to the component to supply the energy then this is supplied from the electrochemical energy in the battery.

The battery pushes electrons up a potential difference through the circuit from - to +

Here I get a bit hazy

The electrons are pushed through the component and 'lose energy'? while they are travelling through it? This lost energy is used by the resistors, lcds etc to do 'their thing'.

What is different in the electron that leaves the neg terminal and reaches the pos terminal?

Is it in a lower energy state?

Also this electron that returns to the battery. Dosnt it go on to take part in a chemical REDOX reaction? How does that happen?

Why does it need to be in a lower energy state to work?

Sorry total confusion as you see. Id be grateful if someone could give me a heads up!
