Sagot :
The answer is (4).
An electron and a proton both have the same quantity of charge, namely about 1.602e-19 C, but whereas protons are positive, electrons are negative. This is why elements in their natural state (same number of electrons as protons) are neutral.
(4) the same quantity of charge and the opposite sign
Further Explanation
Protons, neutrons, and electrons are generally called subatomic particles. They are important components for building atoms. Each atom has a different number of protons, neutrons, and electrons. And ask how the atom maintains its identity and uniqueness. They have different charges and different masses. Also, the role of each subatomic particle is very different from each other. The main difference between Protons, Neutrons, and Electrons can be found in the charge. Protons are positively charged and neutrons are neutral while electrons are negatively charged.
Protons are positively charged. The charge, in this case, is determined by the number of coulombic charges an electron has. The charge of a proton is the same as loading an electron and, approved, can be expressed as 1e. (1e = 1,602 * 10 ^ (- 19) C).
Protons, along with neutrons, are called "nucleons." There are one or more protons in each atom. The number of protons is different in each atom and makes the identity of the atom. When elements are grouped together in a periodic table, the number of protons is used as the atomic number of the element.
Electrons are the third type of subatomic particles, and they are found to orbit around the nucleus in discrete energy levels with discrete. Just like the number of protons, the number of electrons in an atom which carries the identity of each element. The way electrons are published in each element is expressed by their electronic configuration. The number of electrons is similar to the number of protons found in an element. The electron is symbolized as 'e.' Electrons are the only subatomic particles that take part in chemical reactions. They also take part in certain reproductive reactions.
