Answer is: A) Sr (strontium).
The reactivity series<span> is a series of metals from highest to lowest reactivity.</span><span> Metal higher in the reactivity series will displace another.
</span>Strontium is only higher in this group from magnesium. Strontium is stronger reducing agent than magnesium, gives electrons easier.

Is this atom more likely to gain electrons or to lose electrons? Explain how you can tell
elena55 [62]

Answer:

Likely to gain electrons

Explanation:

The atom shown is likely to gain additional electrons to complete its electronic configuration.

  • Since this is a neutral specie, the number of protons and electrons are the same.
  • The atom has 16 electrons
  • the number of valence electrons is 6
  • If the atom gains two additional electrons, the octet configuration is attained
  • Also, the atom can lose 6 electrons to become an octet

The atom will prefer to gain additional 2 electrons to give an octet configuration.

When determining molecular polarity, which scenario is not possible:
Fynjy0 [20]

Answer: Option C is correct

A polar molecule with nonpolar bonds

Explanation:

A polar molecule with nonpolar bonds cannot be polar because a polar molecule has net dipole that it has one end slightly positive and the other end slightly negative which allows the distribution of atoms .

Therefore it cannot have non polar bonds because non polar bonds allow electrons to be shared equally and it take place between non elemental substances or substances that are not elements , it cannot occur in elemental substances because these substances have different electronegativities which can be held by polar bonds alone.

Parts of a neuron include:<br> A. dendrites.<br> B. hormones.<br> C. cortexes.<br> D. collosums.
Tcecarenko [31]

The parts of the neuron include (A) dendrites.

<h3>What are dendrites?</h3>
  • Dendrites are appendages that are designed to receive communications from other cells.
  • They take the shape of projections with a tree-like structure that are triggered by other neurons and carry the electrochemical charge to the cell body.
  • These occupy a large surface area of a neuron.
  • These little appendages convey electrical stimulation to the soma and take in information from neighboring neurons.
  • Synapses are also found on dendrites.
  • Dendrites are also called the "arms" of a neuron.

As it is given in the description, Synapses are also found on dendrites.

Therefore, the parts of the neuron include (A) dendrites.
