According to me the atomic size of an atom increases or decreses with the change in the number of shells. As atomic size is defined as the distance between the nucleus and valence shell of an atom. So, the addition of an electron does not effect the atomic size. As we can see in the periodic table that while moving along a group the number of electrons increases along with increase in no. of shells, while the atomic size tends to be increase with addition of shells and neglecting the addition of electrons. Same is the case while moving along a period. Atomic size decreases while the attraction between increased nuleus charge increases . Thus the size of the atom decreases.
Along a period, nuclear charge increases. hence, atomic radius decreases.
Can be divided into 5 symmetrical parts along a central axis. For example a star fish and sea erchins
Atomic number increases down the group and along the period as well.

The new cell wall forms along the cell plate that forms between the two daughter nuclei of a plant cell.
atomic bombs get there power from the energy released by splitting an atom. A nucleus is fired into an unstable isotopse such as Uranium 235 and the Uranium is split into two daughter nuclei. A cloud of electrons, along with some energy, is released. Each of the electrons in turn splits another atom, creating a large chain reaction, and this releases enough energy to power an atomic bomb.
A cell plate forms between the two daughter nuclei, along which a new cell membrane and cell wall will be laid.
The atomic radius decreases along a period. It is because of increasing effective nuclear charge along a period.

The atomic radius decreases along the elements across a period. Along a group, there is an increment in the atomic radius of corresponding elements.
The atomic number must be known along with the mass number. Then the number of protons or electrons is the same as the atomic number, and the number of neutrons is the difference between the mass number and the atomic number.
