Albert einstein changed the way we think about gravity by using the results of many new experiments to explain that giant objects like earth bend the space around them. according to einstein, this bending of space makes smaller objects move toward larger objects. which statement best explains whether einstein’s idea is a theory or a law? it is a theory because it is a statement of fact that does not include an explanation. it is a theory because it was developed with many new experiments, and it explained the observations. it is a law because it is a statement of fact that does not include an explanation. it is a law because it was developed with many new experiments, and it explained the observations.

The correct answer will be- It is a theory because it was developed with many new experiments, and it explained the observations.

Explanation:

Albert Einstein is one of the genius who worked on explaining the relationship between space and time and gave a theory of relativity.

He was a theoretical physicist who used the results of the experiments performed prior to him like Newton's gravity. He tried to explain the role of gravity in the rotation of planets around large objects which were proved later after publishing his theory.

He explained that light bends or gets deflected when reaches a heavy object due to the gravity of the object. This was proved later in 1919 during the solar eclipse and the repeated experiments afterwards. This proved that his concept is a theory which explained many natural phenomena.

Thus, the selected option is the correct answer.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
