Answer:
The correct answer would be - strontium, magnesium, beryllium.
Explanation:
As we know that the number of the same valence electrons is most likely to exhibit similar physical and chemical properties so the elements of the particular group in the periodic table have a similar number of physical and chemical properties and a similar number of the valence electrons.
For example, group 2 elements are known as alkaline earth metals, and strontium, magnesium, beryllium, and calcium are the same group elements thus, they have the same chemical and physical properties as they have 2 valence electrons.

Answer: Neurotransmitter
Explanation:
Neurotransmitter are refers to as chemical messengers, which are secreted by the nerves cells, to stimulate neighbouring neuron, thereby allowing impulses to be passed from one cell to next, throughout the entire nervous system. Neurotransmitter are released by the axon terminal, after an action potential has reached the synapse, which the is the neuron transmit signal. Neurotransmitter are often released when, electric signal gets to neuron, it triggers the vesicles that contains neurotransmitters, which will split neurotransmitters into the synapse.
