Match the element with its description.

match term definition

sodium a) highly reactive gas

silicon b) nonreactive gas

bromine c) has properties of both metals and nonmetals

argon d) malleable, soft, and shiny

Sodium -  D) Malleable, soft, and shiny

 Sodium is an alkalyne metals that is why they are soft and sodium can cut by knife.

Silicon  -  C) Has properties of both metals and nonmetals

 As we know that those materials have both nonmetals and  metals  properties are known as metaloid.

Bromine  -  A) Highly reactive gas

 All halogens are so reactive .Because they are high electro negative element.Bromine(Br) is a halogen element.

Argon - B) Nonreactive gas

  All noble gases are stable that is why they are not reactive with ant other element.So we can say that noble gas are  Nonreactive gas.Argon(Ar) is noble gas.

i don't know, you need to give me some answers.

explanation:

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
