An anion has gained electrons and therefore has more electrons than protons. It has a negative charge.
An example if this doesn't make too much sense.
Charged Atoms: If electrons are removed from an atom, that atom becomes positively charged because it has more positive charge carriers (protons) than negative charge carriers (electrons)
These types of charged atoms are called positive ions or, cations. DEPENDING ON THE CIRCUMSTANCES, the removed electrons can remain free or they may attach themselves to another atom that can accept extra electrons. If this occurs, a negatively charged ion, or anion, is created.
I hope I made this clear enough for anyone who needed help on this. Hope this helps!!! Have a great day :)))
Answer:
Ionic Bond
Explanation:
Ionic bonding occurs when there is a significant difference in electronegativity between atoms, resulting in the transfer of electrons. In the case of magnesium (Mg) and oxygen (O), magnesium, with a lower electronegativity, donates two electrons to oxygen, which has a higher electronegativity. This leads to the formation of Mg²⁺ cations and O²⁻ anions. The resulting electrostatic attraction between these oppositely charged ions forms an ionic bond, resulting in the creation of magnesium oxide (MgO), a compound with a crystal lattice structure.
and a temperature of
(1) 0°C (3) 273°C
(2) 100°C (4) 373°C
Answer:
1. Receptor: where stimulus action is.
2. Sensory Neuron: responsible of transmitting afferent impulses to the central nervous system.
3. Integration Center: Sensory impulse to motor impulse; Direct (monosynaptic) or polysynaptic region in CNS.
4. Motor Neuron: Efferent impulses from integration center to effector.
5. Effector: Muscle fiber or gland cell that responds to the efferent impulses.
B. receptor, sensory, interneuron, motor, effector
