What happens to the size of an atom as you move top to the periodic table?

Size typically increases going down a group due to an increasing number of electron shells, where the inner shells reduce the attractive forces of the nucleus and repel the electrons in the outer shell

∙ 12y agoThe size of atoms of the elements decrease as you move from the bottom to the top of the Periodic Table. This is because an energy level is removed with each period as you move from the bottom period to the top period.

∙ 12y agothe size of atom increase down the group due to increase in shielding effect (addition of extra shell) as the shielding effect increase the force of attraction b/w nucleus and valence electrons decreasees, so atomic size increase down the group

∙ 11y agoDown a group, the number of shells (or energy level) increases and hence the size of the atom increases.

Do the elements in the periodic table have the same mass?
No! The mass of one atom of each element increases as you move down and to the right on a periodic table. The mass of an atom of a particular element is called its atomic mass.
What happens to the reactivity of left to right across the periodic table?
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
What happens to IE when moving down on the periodic table?
The general trend with Ionization energy as you move down a column on the periodic table is that IE decreases. Ionization energy is the amount of energy required to remove an electron from an atom. As you move down a column, the electron moves farther away from the nucleus and the electron shielding effect increases. There is less of a pull keeping the electron in thus making it easier to remove.
What happens to the atomic radius as you move down the periodic table?
Down a group, the atomic radius increases as the number of shells or energy levels increases.
What is the atomic number and its trend on the periodic table?
The atomic number of an element is the number of protons in the nucleus of one atom of that element. In general, atomic numbers increase as you move to the right and down in the table.
What happens to elements as you move down the periodic table?
they do something
The number of electrons in an atom decreases as you move from left to right in the periodic table.?
False
Describe the number of valence electrons in each atom as you move down group 2 in the periodic table?
Every atom in Column 2 of a wide form periodic table has two valence electrons.
Do the elements in the periodic table have the same mass?
No! The mass of one atom of each element increases as you move down and to the right on a periodic table. The mass of an atom of a particular element is called its atomic mass.
What happens to the reactivity of left to right across the periodic table?
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
What happens to the mass number as you move from left to right in the periodic table?
It increases
The number of electrons in an atom decreases as you move from left to right in the periodic table?
No, to the right side
Modern periodic table comparision with other periodic tables?
The old periodic table was arranged according to the mass number (the weight of the atom overall, including neutrons, protons and electrons), whereas the modern periodic table is arranged according to the atomic number (which only includes the number of protons present in the atom, and increases by one as you move from left to right across the table). This makes a difference because some atoms have unequal numbers of protons and neutrons, which can throw off the weight of the atom.
What happens to the category of elements as you move left to right on the periodic table?
the number of collecting protons gets bigger.
What happens to the reactivity of non metals if you move from left to righton the periodic table?
in general they become more reactive.
What happens to IE when moving down on the periodic table?
The general trend with Ionization energy as you move down a column on the periodic table is that IE decreases. Ionization energy is the amount of energy required to remove an electron from an atom. As you move down a column, the electron moves farther away from the nucleus and the electron shielding effect increases. There is less of a pull keeping the electron in thus making it easier to remove.
What happens to the atomic radius as you move down the periodic table?
Down a group, the atomic radius increases as the number of shells or energy levels increases.
