How is the universe organized from biggest to smallest?
The universe is organized in a hierarchical structure from largest to smallest as follows: universe, observable universe, galaxy, solar system, planet, moon, and then down to subatomic particles like protons, neutrons, and electrons.
What is the organization of an atom?
An atom is organized into a nucleus at its center, which contains protons and neutrons. Electrons orbit the nucleus in electron shells at varying distances. The number of protons in the nucleus determines the element of the atom.
What does the group of the periodic have to do with reactivity?
The table was organized so that elements of similar properties are in the same group. What (partly) determines reactivity is the number of electrons an atom has in it's ground state. . Within the atom electrons are organized in shells. Atoms are stable when they have 8 electrons in their outer shell (for hydrogen and helium it is 2 electrons.) . Elements of: Group 18 have 8 electrons in their outer shells Group 17 have 7 electrons in their outer shells Group 16 have 6 electrons in their outer shells Group 15 have 5 electrons in their outer shells Group 14 have 4 electrons in their outer shells Group 13 have 3 electrons in their outer shells Groups 3-12 have varied number of electrons in their outer shells Group 2 have 2 electrons in their outer shells Group 1 have 1 electron in their outer shells
What must be applied to make the electrons move in the same directions?
To make electrons move in the same direction, an electric field must be applied. This can be achieved by connecting a voltage source, such as a battery, which creates a potential difference. The electric field exerts a force on the electrons, causing them to flow in a coordinated manner, typically through a conductor. This organized movement of electrons constitutes an electric current.
Summarize how the periodic table is organized and tell this organization is useful?
The number of electrons an element has determine the organization. This table helps in making predictions about how an element will chemically react.
Electrons are organized in a series of?
electron shells
How are electrons in an organized?
Electrons occupied certain discrete energy levels around the nucleus.
How does the arrangement of electrons in a magnet compare to metals that are not metallic?
electrons in magnets are organized and generally pointing in the same direction
How are electrons in a atom organized?
Electrons are generally gathered around an atom beginning with the lowest possible quantum numbers.
How are electrons in atom organized?
Electrons occupied certain discrete energy levels around the nucleus.
Electrons are organized in a series of what?
orbitals, each of which can hold 2 electron of opposite spin.
Electrons are organized in a series of what around the nucleus of an atom?
Electron shells, orbitals, and sub-orbitals.
How are elements listed on the periodic tabel?
They are organized by atomic number (the number of protons/electrons in the element).
What is the best description of how an atom is organized?
An atom is organized with a nucleus at its center, containing protons and neutrons. Electrons orbit the nucleus in specific energy levels or shells. The nucleus is positively charged, while electrons are negatively charged, creating a stable, neutral atom.
The elements within the periodic table are organized by?
1) atomic number (number of protons) 2) valance electrons
Where do electrons collect?
Electrons collect in the outer energy levels of atoms, known as electron shells. These shells are organized around the atomic nucleus and can hold a specific number of electrons based on the atom's atomic number and electron configuration.
How are the electrons organized in the periodic table?
The modern periodic table is arranged in the increasing order of their atomic number and repeating properties. The elements in the same family / group have the same number of valence electrons.
