Atoms are made of 3 types of subatomic particles ; protons, neutrons and electrons
protons and neutrons are located inside the nucleus and electrons are found in energy shells around the nucleus. Protons are positively charged, electrons are negatively charged and neutrons are neutral. elements in their ground state are neutral with equal amounts of protons and electrons.
Atomic number is the number of protons. atomic number is characteristic for the element.
atomic number of Be is 4 therefore Be has 4 protons
answer is B. 4
The percent error in the initial measurement would be 6.47%
<h3>Percent Error</h3>
Percent error in any measurement is mathematically given as:
absolute error/true measurement x 100%
In this case;
True measurement = 1.34 qt
Absolute Error = 1.34 - 1.25
= 0.09 qt
Percent error = 0.09/1.34 x 100%
= 6.47%

Answer:
c. 2-methyl-1-butanol.
Explanation:
As depicted in the question; the number of electrons produced is straightforwardly relative and directly proportional to the content and substance of carbon in the atom. So 2-methyl-1-butanol has the most highest and noteworthy carbon content (5carbons) among the accompanying species. So it will generate and create the biggest detector reaction response.
Answer:
Its existence was determined by an English scientist studying nature.
Its existence was established after the invention of the microscope.
Explanation:
I know because atoms are made up by a scientist study chemicals while trying to learn about atoms as well.
