While on the bottom, shrimp use their walking legs (periopods), they use their swimming legs (pleopods) to swim or their tails for a quick, short movement (this can be used as a defense mechanism).
As you move across a period, elements have the same number of electron shells but different numbers of valence electrons. This leads to differences in reactivity and chemical properties across the period.
As you move down a group or column in the periodic table, the number of energy levels or shells increases. Each row in the periodic table represents a different energy level, with elements in the same row having the same number of electron shells.

As you move down a group in the periodic table, shielding increases because there are more electron shells surrounding the nucleus. These additional electron shells act as a barrier, reducing the attraction between the nucleus and outer electrons, thus increasing shielding.
Electrons are found in electron shells surrounding the nucleus of an atom. They move rapidly within these shells, which are composed of energy levels that determine the electron's distance from the nucleus.
yes!
Elements in the same row, or period, of the periodic table fill up the same energy level as you move from left to right. This is because elements in the same period have the same number of electron shells.
As you move across a period, elements have the same number of electron shells but different numbers of valence electrons. This leads to differences in reactivity and chemical properties across the period.
the valence electrons
electrons
they both have shells and they move slow
no they do not. Infact turtle shells are actually part of their body. The spine is connected to the shell
electron shells
they have two shells held together by hinges and strong muscles
Be more specific. Crabs have shells and they use their legs.
Bohr ring
Electrons are the particles found in shells around a nucleus. They are negatively charged and move in orbitals at specific energy levels.
