A positive change atom of hydrogen-ion. A normal hydrogen atomic nucleus
Answer:
An atom becomes charged when there is an unequal amount of positive and negative particles in the nucleus.
An atom gets a positive charge when there is an increase in protons or a decrease in electrons, such that there are more protons than electrons in the nucleus.
An atom gets a negative charge when there is an increase in electrons or a decrease in protons, such that there are more electrons than protons in the nucleus.
An atom can get a charge with a change of particles in the nucleus if that change results in an uneven number of protons and electrons.
Explanation:
Because protons are positively charged particles and electrons are negatively charged particles, a neutral atom has an equal amount of protons and electrons, so that the opposite charges of the particles cancel each other out.
However, if there is an unequal amount of protons or electrons in the nucleus, the charge of the particles will no longer be canceled out, and the atom as a whole will take on a positive or negative charge.

Answer:
When writing an ion, state symbols of the substances must be clearly indicated.I HOPE IT HELPS I MADE AN EXAMPLE TOO:)
Explanation:
<u>Example:
</u>
<u>
Write the ionic equation for the word equation
</u>
Sodium chloride(aq) + silver nitrate(aq) → silver chloride(s) + sodium nitrate(aq)
<u>
Solution:
</u>
<u>
Step 1: </u>Write the equation and balance it if necessary
NaCl(aq) + AgNO3(aq) → AgCl(s) + NaNO3(aq)
<u>Step 2: </u>Split the ions. (Only compounds that are aqueous are split into ions.)
Na+(aq) + Cl-(aq) + Ag+(aq) + NO3-(aq) → AgCl(s) + Na+(aq) + NO3-
<u>Step 3: </u>Cancel out spectator ions. (Spectator ions are ions that remain the same in their original states before and after a chemical reaction.)
<u>
Ionic Equation
</u>
<u>Step 4: </u>Write a balanced ionic equation
Ag+(aq) + Cl-(aq) → AgCl(s)
