Isabel needs an image to represent the carbon cycle for a presentation in her science class. She has the following diagrams to c

hoose from
(A.)model A would be the best model for the carbon cycle because carbon depletes over time as it is used by different organisms.
(B. )model B would be the best model for the carbon cycle because carbon will follow the same path when it is transferred from one place to another
(C. )model ac would be the best model for the carbon cycle because the carbon cycle has definite beginning and end where carbon eventually cannot be reused
(D. )model D would be the best model for the carbon cycle because the carbon cycle is a flow of matter which can take different paths bringing carbon back to the same place​

Metals have high melting and boiling points and are often shiny and silvery. Which of the blocks are metals?
DanielleElmas [232]

Answer:

S and p blocks elements are considered metals while d-block elements are considered transition metals.    

Explanation:

s-block consist of lithium, sodium, potassium, rubidium, cesium and francium metals.

All are these called alkali metals.

These metals have one valance electron.

These metals are soft and having low density.

They easily lose their one valance electron and form cation with +1 charge.

They have low melting points.

P- block elements includes beryllium, magnesium, calcium, strontium, barium, radium metals.

They are called alkaline earth metals.

All are these have two valance electrons.

They easily lose their valance electrons and form cation with charge of +2.

These metals are also very soft.

They form salt with halogens.

They are also very reactive metals.
