what are two conditions atoms must have in order to form covalent bonds with one another

Answers

Covalent bonds are formed mainly between two non metals as electrostatic or ionic bond is prevented from being formed take the example of methane or CH4 (4 means four atoms of hydrogen) in this covalent bonding one atom of carbon combines with four atoms of hydrogen carbon also forms a large number of compounds or more commonly called hydrocarbons due to its property called catenation here hydrogen wishes to gain one electron to obtain duplet atomic structure of helium its closest noble gas element and carbon requires eight electrons in its outermost shell to attain a stable electronic configuration therefore carbon give one electron to each of the four hydrogen atoms and hence hydrogen attain the duplet electronic configuration having two electrons in its outermost shell and carbon loses four electrons from its outermost shell and four hydrogen atoms gain one electron from carbon forming methane covalent bond

planet in the solar system.

Answers

Answer:

Weight

Explanation:

The weight of an object is different on every planet in the solar system.
Weight is the gravitational pull of an object towards the surface of a planet.
It is measured in Newtons, using a spring balance .
Weight changes from one place to another depending on the gravitational acceleration of a surface.
For example, the weight of an object on the surface of the earth is different from the weight of the same object on the surface of the moon.
Mass of an object, on the other hand, remains constant and is the same on every planet in the solar system.
