What does the period tell you about electrons?
The period tells you how many energy levels an atom has.
How many electrons are in the nucleus of an atom with the atomic number of 20?
None. Electrons are found in energy levels outside the nucleus, not in it. An atomic number of 20 tells you there are 20 protons in the nucleus of an atom, and 20 electrons in energy levels (or shells or orbitals depending on which model of the atom you are using) outside the nucleus.
How many energy levels are found in an atom of carbon?
There are 2 energy levels in a Carbon atom. The first energy level consists of '1s' orbital, and the second energy level consists of the '2s' orbital and the '2p' orbital.
How do you know how many rings an atom will have?
The number of electron rings an atom will have is determined by the energy levels of its electrons. Each energy level can hold a specific maximum number of electrons, and atoms will fill these levels in a specific order according to the Aufbau principle. The number of rings an atom will have ultimately depends on the number of electrons it has and how they are distributed among the energy levels.
How many valence electrons does a neutral Be atom have?
It depends on the atom.Atoms may have up to three energy levels, or layers of electrons, although some elements, such as helium, have only one. If an atom has one energy level, its valence electrons may total up to only two. If it has two or three energy levels, It may have up to eight total valence electrons. An atom is neutral when it has the greatest possible number of electrons.
How many energy levels are in a chlorine atom?
Answer3 energy levels17 protons and electrons
How many energy level found in an atom of plutonium?
Electrons in the plutonium atom are placed in 7 energy levels.
How many energy levels in a neutral atom of xenon and how many electrons would be left over?
A neutral atom of xenon has 6 energy levels, with 54 electrons occupying those levels. Xenon has 54 electrons in total, so no electrons would be left over in a neutral xenon atom.
How many electrons are there in a iron atom?
There are 26 electrons in an iron atom. Each neutral iron atom has a total of 26 electrons occupying various energy levels or electron shells.
Energy levels in an atom?
In an atom, electrons can occupy different energy levels, or orbits, around the nucleus. Electrons in the lowest energy level are closest to the nucleus and have the lowest energy, while electrons in higher energy levels are farther from the nucleus and have higher energy. Electrons can move between energy levels by absorbing or emitting energy in the form of photons.
How many inner shell electrons do selenium atom have?
A selenium atom has 36 inner shell electrons. This includes electrons in the first (2 electrons) and second (8 electrons) energy levels, as well as 18 electrons in the third energy level.
How many clouds does a platinum atom have?
A neutral atom of platinum has 78 electrons, at 78 energy levels in one cloud.
If an atom has 11 electrons how many energy levels will it have?
The atom will have 3 energy levels. The first energy level can hold up to 2 electrons, the second level can hold up to 8 electrons, and the third level can hold the remaining electron.
How many electrons does each of the levels of an atom hold?
Maximum of 2n2 where n is the energy level
What does the period tell you about electrons?
The period tells you how many energy levels an atom has.
How many energy levels does carbon have?
Carbon has 2 energy levels. There are 6 electrons, 6 protons, and 6 neutrons.
How many energy levels are occupied in an atom of oxygen?
An atom of oxygen has 2 energy levels that are occupied - the first energy level (K shell) can hold up to 2 electrons, and the second energy level (L shell) can hold up to 6 electrons. Oxygen has a total of 8 electrons.
