Answer:
We know the information about atomic size, energy, electronic configuration etc. of atom from the periodic table.
Explanation:
- Periodic table is the arrangement of elements that are arranged according to their properties and electronic configuration.
- In periodic table, on furthest right side of the periodic table, noble gases like He, Ne, Ar etc are arranged.
- The atomic number of element increases while moving from left towards right in the periodic table.
- The metallic character of element decreases as we proceed the table towards right.
- They readily accept electron to fill the valence shell hence becoming more metallic in character.

Answer:
<em>Vernal equinox, autumnal equinox, march equinox, September equinox, northward equinox and southward equinox </em><em>are the names for the equinoxes.
</em>
<u>Explanation:
</u>
There are different names which are named depending on the <em>month of the year when these equinox occurs and depends upon direction of motion of the sun</em>.<em> Equinox is a point where day time and night time have exactly equal length of time.</em>
Equinox occurs <em>twice</em> in a year and this occurs when <em>earth's equator passes through the sun</em>. We can say that equinox occurs when the sun’s center is directly above the equator.
A light-year is a unit of length or distance.
It's defined as the distance that light (or any electromagnetic
wave) travels through vacuum in one Earth-year.
