Which of the following ions has the smallest radius? 1 Ca2+ F- K+ Cl-- Your answer is incorrect.? Asker's rating. 1  Cl- has the smallest radius due to the fact that atoms' radii get smaller as you go up and to the right in the periodic table. 2  F- has the smallest radius. 3  Sice flourine is in the lowest energy level so it has the lowest radius. 4  fluorine.

Mercury (planet) It is the smallest planet in the Solar System, with an equatorial radius of 2,439.7 kilometres (1,516.0 mi). Mercury is also smaller —albeit more massive—than the largest natural satellites in the Solar System, Ganymede and Titan. Mercury consists of approximately 70% metallic and 30% silicate material.

Scientists Discover Smallest Known Star Stars come in a variety of sizes; the smallest stars, known as red dwarfs, can possess as little as 10% of the mass of our Sun, whereas the biggest stars (hypergiants) can be over 100 times as massive as the Sun.

Circle Radius, Diameter and Circumference. The Radius is the distance from the center to the edge. The Diameter starts at one side of the circle, goes through the center and ends on the other side. The Circumference is the distance around the edge of the circle.ecause people have studied circles for thousands of years special names have come about. Nobody wants to say that line that starts at one side of the circle, goes through the center and ends on the other side when a word like Diameter will do.

Which element has smallest atomic size? As at. size decreses atomic no i,e. nuclear charge increases.Helium has at no 2 .It has smallest atomic size.It is smaller than Hydrogen bcoz the nuclear charge is greater, and the 2 electrons occupy the same orbital as does the single electron in the hydrogen because the nuclear charge is greater, and the 2 electrons occupy the same orbital as does the single electron in the hydrogen atom.

- Narrower than a phone box & shorter than a Vespa, the P50 microcar is officially the World’s Smallest Car. Made on the Isle of Man in the early 1960s, fewer than 30 exist today making it one of the rarest cars in the World. Famously TV presenter Jeremy Clarkson drove a 1963 P50 through the BBC right up to his desk.

- mass m density d Volume V = = For any pure substance or homogenous mixture, density is an intensive quantity, which means that its value is the same no matter how much of the substance is present. Density expresses the proportional relationship between mass and volume of the substance. If the density of a particular substance is given in grams per milliliter, it indicates the number of grams present in 1 milliliter of that substance. Conversely, the reciprocal of density tells the number of milliliters present in one gram of the substance.

What is the smallest planet and largest planet in our solar system? The smallest planet in regards to both mass and volume is Mercury—this tiny world is nearly 20 times less massive than Earth, and its diameter is about times 2 ½ smaller. In fact, Mercury is closer in size to our Moon than to Earth.

Differences between the Inner and Outer Planets Small size. Earth is the largest of the Inner Planets, with a diameter of 12,756 km (7,926 miles). Mercury is the smallest with a diameter of 4,878 km (3,031 miles) Huge! Jupiter, the largest planet, has a diameter of 142,984 km (88,846 miles). Neptune is the smallest of the Outer Planets with a diameter of 49,532 km (30,779 miles) Have solid surfaces and thin/no atmospheres. In theory, it would be possible to stand on each of the Inner Planets, although you would only survive on Earth.

Why Pluto is No Longer a Planet The smallest planet in the Solar System is Mercury (the biggest planet is Jupiter). For the longest time, the smallest planet was considered to be Pluto, but now Pluto isn’t a planet any more, so we’re back to Mercury. Mercury measures 4879 km along its equator. Just for comparison, Earth is 12,742 km across. So Mercury is only 38% the diameter of Earth.

- this is due to the rotation spin of the earth that produces a slight bulge at the equator we call this shape an oblate spheroid or an ellipsoid this ellipse has a smallest radius of 6356 752 km at the poles and a largest radius of 6378 137 km at the equator even this ellipsoid is not completely level

Ceres: The Smallest and Closest Dwarf Planet [ Infographic: Dwarf Planets in the Solar System ]. The largest object in the asteroid belt, Ceres makes up nearly a third of its mass. Even so, it remains the smallest known dwarf planet, only 590 miles (950 km) across — roughly the size of Texas.n Jan. 1, 1801, Sicilian astronomer Giuseppe Piazzi discovered what was then considered a planet, naming it Ceres for the Roman goddess of corn and harvests. Within a decade, four new objects were discovered in the same region, all also considered planets.

- The radius is slightly smaller than the ulna and pivots around the ulna to produce movement at the proximal and distal radioulnar joints. Proximally the radius terminates with a disk shaped head which articulates with the capitulum of the humerus and the radial notch of the ulna.

Pluto: The Farthest Planet ( Usually) Pluto turns out to be only about 2300 kilometers across (1400 miles) — clearly making it the smallest planet in the solar system. In fact, seven moons (including the Earth's) are larger than Pluto. Charon is about 1300 kilometers wide (or roughly 800 miles).

- No, Earth isn't the smallest planet. Earth is the fifth largest planet in our Solar System. It is larger than all the other inner (or 'Rocky') planets (Venus, Mars and Mercu…ry) but smaller than the 4 outer planets (Jupiter, Saturn, Uranus and Neptune) . Mercury is the smallest planet despite the fact that a multitude of smaller objects orbit the Sun.

Ceres is a dwarf planet, the only one located in the inner reaches of the solar system; the rest lie at the outer edges, in the Kuiper Belt.While it is the smallest of the known dwarf planets, it is the largest object in the asteroid belt.he largest object in the asteroid belt, Ceres makes up nearly a third of its mass. Even so, it remains the smallest known dwarf planet, only 590 miles (950 km) across — roughly the size of Texas.

Which element has smallest atomic size? Answer Wiki. H have one proton in nucleus and one electron revolving around nucleus and He have two protons in nucleus and two electrons around it's nucleus. He nucleus have more attractive force on its outer electrons since its charge is double that of H making electron revolve in lower radius orbit.Thus He has smallest atomic size. for practical values, Radius of H =53 pm and Radius of He =31 pm
