get larger
Density increases down a group on the periodic table. The trend is more complex across a period. Metals are generally more dense than nonmetals, but among metals on a period, density increases to the right.
As you go down the periodic table, the density generally increases. This is because the atomic mass and atomic size of elements increase as you move down a group, resulting in a greater mass packed into a larger volume. Exceptions can occur due to fluctuations in atomic structure or intermolecular forces.
they do something
The density of elements generally increases from left to right across a period in the periodic table and decreases down a group. This trend is due to the increasing atomic mass and decreasing atomic volume of elements. Higher density elements tend to have higher melting and boiling points, as well as greater hardness and strength.
The trend in atomic radii as you move down Group 1A elements is partially due to the increase in the number of electron shells or energy levels. As you move down the group, each subsequent element has an additional electron shell, leading to an overall larger atomic size.
As we move down the group ,the electrons in the valence shell remains constant but the number of shells increases by one.size of the element increases down the group .elements are more electro-positive as we move down the group so elements at the bottom are more electro-positive than those at the top.as the size of the elements increases the nuclear charge on the elements decreases.due to less nuclear charge shielding effect decreases down the group.
Things freeze & then sink because of the amount of density the object contains.
Hydrogen with 0.09 density
Down the group, atomic radius increases. This is due to increase in number of shells.
bend towards the normal and slow down due to the increase in optical density.
As you move further down towards the Earth's core, the density of the layers increases. This is because the pressure increases with depth, causing the materials to become more compact and closely packed together. The outermost layer, the crust, is less dense compared to the layers beneath it, such as the mantle and the core.
Iridium is the elemento with the highest density
