it is a numerical arranged order im a high school teacher
numerical order
they arranged it from the top row to the bracket on the keyboard.
They are arranged alphabetically. Nice!
made of grain (Cereal) arranged in regular order (Serial)
Electrons are arranged in energy levels or shells around the nucleus of an atom. The first shell can hold up to 2 electrons, while the second and third shells can hold up to 8 electrons each. The electrons fill up the shells in order of increasing energy levels.
The number of electrons in the atom increase from left to right and then from top to bottom.
electrons are arranged in energy levels, or shells, around the nucleus of an atom.
Electrons are arranged in shells, subshells and orbitals.
There are 35 electrons in a neutral boron atom arranged in the order 2, 8, 18, 7.
Dmitri Mendeleev and Lothar Meyer first arranged the elements in the increasing order of atomic masses. Bohr and Henry Moseley then arranged the elements in the increasing order of atomic number.
Sodium atoms do have electrons that are arranged in energy levels. The electron configuration of sodium is 1s22s22p63s1.
Electrons are arranged in shells around the nucleus.
Helium has only two electrons. Both the electrons are arranged in the 1st energy level or 1s orbital.
Atomic number, which is the same as the number of protons in each atom of an element.
Across periods (horizontally, by rows) they are arranged in order of their increasing proton number (= atomic number).Downwards (in columns) the groups are arranged so that:elements with similar properties fall into the same columns andthey have the same number of electrons in the outer ('valence') shell.
