Explanation:

protons have a relative charge of +1, they are located in the nucleus and the carry a positive charge

the electrons are negatively charged and have a charge of -1 . They are found orbiting on the shells .the electrons have a negligible mass of 1 / 1840

the neutrons have no charge they are located in the nucleus of an atom .

A sample of nitric acid contains both H3O ions and NO3 ions. This sample has a pH
bearhunter [10]

Answer : The name of positive ion present in this sample is, hydronium ion.

Explanation :

For formation of a neutral ionic compound, the charges on cation and anion must be balanced.

The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Ion : An ion is formed when an atom looses or gains electron.

When an atom looses electrons, it will form a positive ion known as cation.

When an atom gains electrons, it will form a negative ion known as anion.

As per question, hydronium ion or hydrogen ion is having an oxidation state of +1 called as H_3O^{+} or H^+ cation and nitrate ion NO_3^{-} is an anion with oxidation state of -1.

Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral HNO_3.

Hence, the name of positive ion present in this sample is, hydronium ion.

Where do the heaviest elements in our solar system come from?
Lady_Fox [76]
The formation of elements heavier than iron and nickel requires the input of energy. Supernova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel. The nuclei with mass heavier than nickel are thought to be formed during these explosions.
