The correct answer is C. It was based on the thoughts of an early philosopher.
Explanation:
An atom is a basic and smallest unit that composes matter and that determine the properties of elements. Regarding the development of ideas related to atoms these did not begin in science but in philosophy; indeed the first person that proposed matter or elements were composed of certain smaller units was the philosophers Leucippus and his pupil Democritus in Ancient Greece, who stated atoms were eternal, infinite and defined the qualities of an object, idea that was supported by other Greek philosophers. But it was not until 16th and 17th centuries after the Middle Ages that the term re-emerged and until the 19th century it was officially proposed and there were experiments by scientists that later became a theory. Therefore, the development of the earliest idea about attoms differs from later work of scientists is that the earliest idea was based on the thoughts of an early philosopher.
The atomic orbitals of the central atom mix to form hybrid orbitals are one s and three p.
<h3>Which atomic orbitals are used to form hybrid orbitals?</h3>
Pauling supposed that in the presence of four hydrogen atoms, the s and p orbitals form four equivalent combinations which he called hybrid orbitals.
<h3>How many bonds does PF5?</h3>
Phosphorus pentafluoride has 5 regions of electron density around the central phosphorus atom (5 bonds, no lone pairs).
The resulting shape is a trigonal bipyramidal in which three fluorine atoms occupy equatorial and two occupy axial positions.

paki sagot naman pls para my isagot ako sa module ko ty
want us to answer? or just look at it XD
Explanation:
Reagents: Water , 1.0 M HCl, Conc. 
Metal-1 = Magnesium
Metal-2 = Sodium
Metal-3 = Silver
a) Out of these three metals sodium is a soft metal which can be easily cut with help of knife.Sodium metal reacts violently with water to form hydrogen gas and sodium hydroxide.
b) Out of magnesium and silver, magnesium metal reacts readily with HClto form magnesium chloride and hydrogen gas. Where as silver being noble metal doesn't get attacked by the HCl.
c) Silver is a noble metal. And noble metals only react with concentrated that is nitric acid.
d) When few drops of HCl were added to the solution of silver and. This will leads to the formation of nascent chloride which reacts with silver metal present in the solution to give silver chloride.
