There are five layers to the Earth (from the inner to the outer):

The Inner Core- This is composed of a heavy metallic material an Iron ball.

The Outer Core- This is composed of liquid metal that revolves around the inner core creating the Van Allen belt, which is responsible from keeping the suns harmful u.v rays off of us.

Both cores are made of Iron and some nickel and are believed to be about 2900km thick

Two other important ones are the mantles the upper and lower mantle the are separated by the temperature of the magma the inner mantle is much hotter than the outer mantle, which is responsible for the rotation of the crusts in a convection type manner the inner core moves up to the surface and grabs the crusts and rotates it then after it settles back to the bottom. For more info look up tectonic plate theory. The two layers for the mantles are known as Mesosphere(2500 km thick) and Asthenosphere(250 to 350 km) Mesosphere is the inner core and it is made up of solid but soft rock that flows smoothly and the Asthenosphere is made up of solid rocks that are slightly melted.
Last and most important because we live on it is the crust, which is known as the Lithosphere this is mainly solid rock and is around 250 km thick
Hope this helps :)

Answer from: Quest

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm

Answer from: Quest

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
