Answer:
Please find the definition and example of neutralization reaction below
Explanation:
In chemistry, neutralization reaction is a type of reaction involving a base and an acid to form salt and water. In other words, when an acid and a base comes together chemically to form a salt and water, a neutralization reaction is said to occur.
For example; in a reaction between sodium hydroxide (NaOH) and hydrogen chloride (HCl) as follows:
HCl(aq) + NaOH(aq) → NaCl(s) + H2O(l)
In this neutralization reaction, the HCk is the acid while the NaOH is the base (reactants). For the products, the NaCl is the salt while H2O is water.
Answer:
atomic number: how many protons
atomic mass: how many protons and neutrons
The atomic radius of a chemical element is a measure of the size of its atom.
The atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.
The atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
Answer:
it should be that I'm pretty sure it's Newton's law
Answer: b. positive charge is concentrated in the center of the atom
Explanation:
Ernest Rutherford conducted a series of experiments together with Hans Geiger and Ernest Marsden; in order to corroborate <em>Thomson's plum pudding atomic model </em>(positive and negative charges evenly distributed in the atom).
However the results of the experiment led him to find out there is a concentration of positive charge in the atom's core (which was later called nucleus) surrounded by electrons. This lead to a new atomic model, in which the atom has a positive charged nucleus surrounded by negative charged particles that move similar to the orbit of the planet around the Sun.
So, according to this model, atoms are mostly empty space with a positively charged core.
