Answer:
The correct option is: a. Photosphere
Explanation:
Sun is the brightest star in the sky of our planet Earth and the principle component of the Solar System. It is a <u>gaseous object</u> that is made up of hot plasma and contributes 99.86% to the total mass of our Solar System.
<u>The Sun does not have a clearly defined surface.</u> The <u>visible surface of the Sun is known as the Photosphere</u>, which is the deepest visible portion of the Sun.
For the noble gasses, you get D, but metals are basically everywhere in the periodic table...
Pls make ur question alittle clearer by may be saying the chemical compound or writing the required reaction
Answer:
If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. The word "kinetic" comes from the Greek word "kinesis" which means motion. Kinetic energy can be passed from one object to another in the form of a collision.
Explanation:
Answer:
Group 1 or akali metals have the greatest metallic property.
Group 17 has the lowest metallic character.
C. As you move from right to lefton the periodic table, metallic character increases which is the ability to lose electrons. Ionization energy decrease as we move from right to left on the periodic table.
Explanation:
Akali metals in group 1 have the greatest metallic property and they are the most reactive metals. Francium metal on the group has the most metallic characteristics. It is rare and very radioactive. Group 17 has the lowest metallic character. This is because while moving across the period, the number of electrons in the outermost shell increases. This make it difficult for atoms to leave see electrons and become electropositive . Group 17 has the highest tendency of accepting electrons.
Ionization energy is the energy use to remove electron from an atom in gaseous stage. Ionization energy decrease as we move from right to left on the periodic table and metallic character increases as we move from right to left on the periodic table.
