Answer: Negative
Explanation:
This is called an anion. Whenever an atom gains a electron, it becomes negative. When an atom loses an electron, it becomes postitive. Positive atoms are called cation.
After an ionic bond is formed, the charge of the atom that gained an electron will be negative.
What is an ionic bond?An ionic bond, also widely recognized as an electrovalent bond, is a category of interconnection established by the electrostatic attraction of ions with opposing charge in a chemical substance.
When the valence (outermost) electrons of one atom are permanently transferred to another atom, a bond is formed.
An ionic bond is formed between a metal and a nonmetal, whereas a covalent bond is formed between two nonmetals.
An ionic bond is formed by the complete transfer of electrons from one atom to another. When an atom loses one or more electrons, it becomes a cation, or positively charged ion.
When an atom gains one or more electrons, it becomes an anion, a negatively charged ion.
Thus, the atom is negatively charged as it gained electron.

Change that happens in a living organism because of a stimulus
Answer: A change in an organism's surroundings that causes the organism to react is called a stimulus (plural stimuli).
