Answer:
Helium and Neon have similar chemical properties because both of them completely fill the outer shell of their atoms' electrons, so there is nothing to share with other atoms, neither with the same element nor with any other element.
Explanation:
Helium and Neon are both noble gases . As elements react, their atoms, by losing, acquiring, or sharing electrons, complete their outer shells. Noble gas atoms already have full outer shells, so there is no tendency for them to lose, gain, or share electrons. There are incomplete outer shells of atoms of group 1 and 7 elements (so they are reactive)
<u>Chemical properties of HELIUM and NEON -:
</u>
- In group 8(or 0) of the periodic table, on the far right side, the Noble Gases are contained. Helium, neon, argon, krypton, xenon and radon are their names.
- They are extremely colourless and unreactive.
- They do not form bonds, so they still remain as single (monatomic) atoms.
- There is very little chemical reactivity in them.
Hence, helium and neon have similar chemical properties as they are the most stable due to having the maximum number of valence electrons their outer shell can hold.
Answer:
Tides are the rise and fall of sea levels caused by the combined effects of gravitational forces exerted by the Moon and the Sun, plus the rotation of the Earth. Tides are caused by the gravitational pull of the moon and sun. High and Low tides are caused by the moon. Spring tides occur twice each lunar month all year long without regard to the season. Neap tides, which also occur twice a month, happen when the sun and moon are at right angles to each other.
