Answer:
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
HOPE THIS HELPED!!!!!!!!XDD
To be honest I good in science
An electric field travels away from a <u>positive charge</u> and toward a <u>negative charge</u>.
<h3>
What is electric field?</h3>
Electric field is the region of space where the impact of electric force is felt.
The electrostatic field is always directed away from positive charges and toward negative charges, and, field lines must go away from positive charges and toward negative ones.
Thus, an electric field travels away from a positive charge and toward a negative charge.

<span>disproportionation is a type of redox reaction in which an element can undergo both oxidation and reduction.
Let's take a look at the choices:
First we have the oxide ion. Oxide ion has a charge of -2 which is the lowest charge that an oxygen atom can have. Therefore, an oxide ion cannot be further reduced, so this choice is not correct.
Next we have the peroxide ion. The oxygen has a charge of -1 which means it can be further reduced. So, this choice is acceptable
Last but not least, we have the superoxide ion. The oxygen has a charge of -1/2 which means it can be further reduced. So, this choice is also acceptable.
Based on this, we have two accepted choices which are b and c.</span>
Answer: Simple,
Explanation: There is only one atom in a monoatomic ion and there are many atoms in a polyatomic
