What element has 3 energy levels and 8 neutrons in its outer energy level?
The element with 3 energy levels and 8 neutrons in its outer energy level is oxygen, with the symbol O. Oxygen has 8 protons and 8 neutrons in its nucleus, with 2 electrons in its inner energy level and 6 electrons in its outer energy level.
What is the result of sharing of electrons in the outer energy levels of two atoms?
Sharing of electrons in the outer energy level of two atoms results in a covalent bond.
What lies at an altitude of 100 km above the sea level is defined as the boundary between earth's atmosphere and outer space?
The boundary at an altitude of 100 km above sea level is known as the Kármán line. It is commonly accepted as the point where the Earth's atmosphere ends and outer space begins. At this altitude, the air density is very low, and spacecraft can achieve orbit without being affected by atmospheric drag.
What is the pressure difference between earth sea level and outer space?
The pressure at sea level on Earth is about 14.7 pounds per square inch (psi), while the pressure in outer space is close to zero psi. This means that there is a pressure difference of 14.7 psi between sea level on Earth and outer space.
What is outer energy level is filled with elections?
The outer energy level of an atom is referred to as the valence shell, and it is filled with electrons when it contains the maximum number of electrons allowed, usually eight for most elements (known as the octet rule). This configuration contributes to an atom's stability and chemical behavior. Atoms with filled outer energy levels tend to be less reactive, as they do not seek to gain or lose electrons. Noble gases, such as helium and neon, have completely filled outer energy levels.
How many outer levels does Cesium have?
One electron in outermost energy level.
What atoms have two outer level electron?
Energy levels
How are the outer energy levels of nonmetals different from metals?
Nonmetals almost have a full outer energy level while metals have few electrons in their outer energy level.
HOW many energy levels does vanadium have?
There can only be 1 outer energy level.
How many miles from land to outer space?
The Kármán line, which marks the boundary between Earth's atmosphere and outer space, is typically considered to be around 62 miles (100 kilometers) above sea level.
What element has 3 energy levels and 8 neutrons in its outer energy level?
The element with 3 energy levels and 8 neutrons in its outer energy level is oxygen, with the symbol O. Oxygen has 8 protons and 8 neutrons in its nucleus, with 2 electrons in its inner energy level and 6 electrons in its outer energy level.
Where does Earth's atmosphere start and end at?
Earth's atmosphere extends to about 10,000 km (6,200 miles) above sea level, but its density becomes increasingly thinner as altitude increases. The boundary between Earth's atmosphere and outer space is known as the Karman line, which is located at an altitude of 100 km (62 miles) above sea level.
Highest level of the atmosphere?
The highest level of the atmosphere is the exosphere, which starts at about 500 kilometers above the Earth's surface and extends out to about 10,000 kilometers. This region is where the atmosphere gradually transitions into outer space and where satellites orbit the Earth.
What is the strong lower part of the mantle between the asthenosphere and the outer core also the layer of the atmosphere between the stratosphere and the thermosphere?
The strong lower part of the mantle between the asthenosphere and the outer core is called the lower mantle. The layer of the atmosphere between the stratosphere and the thermosphere is called the mesosphere.
How many electrons do beryllium and magnesium have in there outer energy levels?
Beryllium and magnesium have two electrons in their outermost energy level, as do all Group 2 elements.
How many energy level does na have?
Na, or Sodium, has 3 energy levels. Two electrons in the first level, eight in the second, and one in the third (and outer most) level.
The outer electron levels of hydrogen?
Hydrogen has only 1 electron and has only 1 energy level.
