Answer:
When electrons are lost, a positively charged ion is formed. When electrons are gained, a negatively charged ion is formed.
Explanation:
Atoms consist of three particles:
- Protons, positively charged, in the nucleus
- Neutrons, no charge, in the nucleus
- Electrons, negatively charged, orbiting around the nucleus
The proton and the electron have same magnitude of charge (), but the proton's charge is positive while the electron's charge is negative.
For a neutral atom, the number of protons is equal to the number of electrons, so the atom is electrically neutral. However, sometimes the atom can lose or gain electrons, becoming electrically charged: this is called ion. In particular:
- If the atom loses one (or more) electrons, it will remain with an excess of positive charge (because the number of protons is now greater than the number of electrons), so it will form a positively charged ion
- if the atom gains one (or more) electrons, it will remain with an excess of negative charge (because the number of protons is now smaller than the number of electrons), so it will form a negatively charged ion

Answer:
Net forces which pushes the window is 30342.78 N.
Explanation:
Given:
Dimension of the office window.
Length of the window = m
Width of the window = m
Area of the window =
Difference in air pressure = Inside pressure - Outside pressure
= atm =
atm
Conversion of the pressure in its SI unit.
⇒ atm =
Pa
⇒ atm =
Pa
We have to find the net force.
We know,
⇒ Pressure = Force/Area
⇒
⇒
⇒ Plugging the values.
⇒
⇒ Newton (N)
So,
The net forces which pushes the window is 30342.78 N.
