Answer:

Sm (Samarium) = [Xe] 4f6 6s2

Explanation:

Noble gas electron configuration of Sm (Samarium) = [Xe] 4f⁶ 6s²

Noble gas electron configuration of Os (Osmium) = [Xe] 4f¹⁴5d⁶6s²

Noble gas electron configuration of Ba (Barium) = [Xe] 6s²

Noble gas electron configuration of Bi (Bismuth) = [Xe] 4f¹⁴5d¹⁰6s²6p³

A completely filled s, p, d, and f orbitals have 2, 6, 10 and 14 electrons respectively. Half filled s, p, d, and f orbitals have 1, 3, 5 and 7 electrons respectively.  Bi and Os have completely filled f orbitals. Sm has partially filled f orbital.

Which total mass is the smallest?
andreev551 [17]
The mass of electrons, protons, and neutrons:
electrons 9.10938291*10^-31 kg
protons 1.67262178*10^-27 kg
neutrons 1.6749*10^-27 kg
the mass of electrons is way smaller than both, the mass of protons and neutrons
therefore, 1) the mass of 2 electrons is the smallest

True of false metals like copper are sometimes used to fill cavities in teeth
ElenaW [278]
I'd say false because copper is what they used to drink out of in the middle ages, and it caused them to get very sick, so I doubt they would use copper in your mouth.

What is the difference among the states of matter at the atomic level?
kolbaska11 [484]
States of Matter
Gases, liquids and solids are all made up of microscopic particles, but the behaviors of these particles differ in the three phases.
Note that:

Particles in a:
gas are well separated with no regular arrangement.
liquid are close together with no regular arrangement.
solid are tightly packed, usually in a regular pattern.
Particles in a:
gas vibrate and move freely at high speeds.
liquid vibrate, move about, and slide past each other.
solid vibrate (jiggle) but generally do not move from place to place.
Liquids and solids are often referred to as condensed phases because the particles are very close together.
The following table summarizes properties of gases, liquids, and solids and identifies the microscopic behavior responsible for each property.

Some Characteristics of Gases, Liquids and Solids and the Microscopic Explanation for the Behavior
gas liquid solid
assumes the shape and volume of its container
particles can move past one another assumes the shape of the part of the container which it occupies
particles can move/slide past one another retains a fixed volume and shape
rigid - particles locked into place
compressible
lots of free space between particles not easily compressible
little free space between particles not easily compressible
little free space between particles
flows easily
particles can move past one another flows easily
particles can move/slide past one another

Question 2<br> What is 3 x 108 written in standard form?
andriy [413]

I think you meant 3.08*10x^{8}

If you want to do that then you it will be 308 , 000 , 000

or if you meant 3 x 108 then it would literally just be 3 multiplied by 108 = 324
