The answer is: Henry Moseley.

Henry Gwyn Jeffreys Moseley (1887–1915) proposed that the number of positive nuclear charges (protons) in atom is equal to its atomic number in the periodic table.

Mendeleev did not know about isotopes and he arranged the elements in order of increasing relative atomic mass.

For example, positions of iodine and tellurium were reversed in Mendeleev's table, because of different isotopes, but Moseley solved anomalies like this one.

<h3>What is an Empire?</h3>

A political unit known as an empire is made up of many different nations and regions that is "often established by conquest and divided into a dominant center and submissive peripheries." By a strict definition, an empire is a sovereign state with an emperor as its head of state; however, not all states with a combined territory under the control of supreme authorities are referred to as empires or ruled by emperors, and not all self-described empires have been recognized as such by historians and contemporaries (the Central African Empire, and some Anglo-Saxon kingdoms in early England being examples).

There have been "brutal and comparatively peaceful, centralized and decentralized, ancient and modern" Empires.

gregori [183]

Answer:

160

Explanation:

p*v/t = constant

or

p1*v1/t1 = p2*v2/t2

pressure is not stated in question so we get rid of it on both sides

v1/t1 = v2/t2

we are finding temperature so we flip the entire equation

t1/v1 = t2/v2

200/5 = t2/4

4(200/5) = t2

=160
