Y means families and are vertical (alkaline, alkaline earthmetals, halogens, transition metals, noble gases, etc)
x means periods andare horizontal (1,2,3,4,5)
Answer:
Explanation:
The covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule. Covalent bonds are established between non-metallic elements, such as hydrogen H, oxygen O and chlorine Cl. These elements have many electrons in their outermost level (valence electrons) and have a tendency to gain electrons to acquire the stability of the electronic structure of noble gas.
The covalent bond between two atoms can be polar or nonpolar. If the atoms are equal, the bond will be nonpolar (since no atom attracts electrons more strongly). But, if the atoms are different, the bond will be polarized towards the most electronegative atom, because it will be the atom that attracts the electron pair with more force. Then it will be polar.
It can occur in a molecule that the bonds are polar and the molecule is nonpolar. This occurs because of the geometry of the molecule, which causes them to cancel the different equal polar bonds of the molecule.
In carbon tetrachloride the bonds are polar, but the tetrahedral geometry of the molecule causes all four dipoles to cancel out and the molecule to be apolar.
When an object/liquid/food etc contains hot energy, the heat particles are moving around causing the heat. 8ounces of soup would cool off faster, because there is less liquid for the heat particles to be in, there for less heat particles, therefore cooling off faster.

According to the research, the correct option is 3, Igneous rocks are those formed from a molten product from volcanic activity.
<h3>What are Igneous rocks?</h3>
They are rocks of high resistance, isotropy, brittleness and density that are created from the cooling and solidification of the magma, whether fragmented or compact, that form at erupting volcanoes, that is, this substance, made up of molten rocks and other elements, is found inside the planet.
When the cooling process takes place superficially and quickly, extrusive igneous rocks are produced, among which are obsidian and basalt, they usually appear after the eruption of a volcano, since the ejected lava solidifies.
Therefore, we can conclude that according to the research, the correct option is 3, Igneous rocks are those formed from a molten product from volcanic activity.
