These feature that was formed by hotspot volcanism is <span>The Big Island of Hawaii. The Hawaiian Islands are actually found at the tip of several volcanoes that has been formed by a series of volcanic eruptions. Today, the Big Island sits on the hotspot, and contains the only active volcanoes of the group of islands.</span>

What is the contrast of these two atoms?
Katena32 [7]

Answer:

The atomic number of silicon is 14 while atomic mass of carbon is 14.

Explanation:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.

In given atoms ¹⁴₆C  and ²⁸₁₄Si the atomic mass of carbon is 14 while the atomic number of silicon is 14. It means silicon has 14 electrons or protons while carbon has 6 protons or electrons because its atomic number is 6. Carbon has 6 protons and 8 neutrons in its nucleus while silicon has 14 protons and 14 neutrons in its nucleus.

In C:

Number of neutrons + protons = 8 + 6 = 14 amu (mass number)

Number of electrons = 6

In Si:

Number of neutrons + protons = 14 + 14 = 28 amu (mass number)

Number of electrons = 14

List a possible set of four quantum numbers (n,l,ml,ms) in order, for the highest energy electron in gallium?
Elena-2011 [213]
Gallum: Z = 31

electron configuration: [Ar] 4s^2 3d10 4s2 4p1

Highest energy electron: 4p1

Quantum numbers:

n = 4, because it is the shell number
l = 1, it corresponds to type p orbital 
ml = may be -1, or 0, or +1, depending on space orientation, they correspond to px, py, pz
ms = may be -1/2 or +1/2, this is the spin number.
