Answer:
The correct option is C) The number of protons is equal to the number of electrons.
Explanation:
Atoms are made up of particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom and form the nucleus, while electrons surround the nucleus. Electrons have a negative charge. The charge of the protons is positive and finally, the neutrons have no charge.
If the atom has no charge, this means that the total charge of the atomic nucleus, which is positive due to the presence of the protons, is equal to the negative charge of the electrons, so that it cancels out.
So, <u><em>the correct option is C) The number of protons is equal to the number of electrons.</em></u>
A person would weigh more on Neptune than on planet earth because the gravitational field strength is stronger on Neptune.
Answer:
yes
Explanation:
the metallic properties of elements tends to decrease across a period and increase down a group.
Answer:
loses, gains
Explanation:
In the ionic compound aluminum selenide, each atom of aluminum will lose electrons while each atom of selenium will gain the electrons.
An ionic compound is an interatomic bond formed between a metal and non-metal. The metal is less electronegative compared to the non-metal. In this case, the metal will lose electrons to become positively charged whereas the non-metal, selenium will gain the electron to become negatively charged.
The electrostatic attraction between these oppositely charged ions leads to the formation of the ionic bond.
Cis is more polar than trans. Cis would be \_/
and trans is /-/. I am hoping that this answer has satisfied your
