What is the atomic number of the element to the right of the periodic table?
The atomic number increases one-by-one stepping to the right (within a specific period) in the periodic table.
How does the physical state of a metal change as the atomic number increases?
sticking to increasing at no within group: more soft
Which of these describes atomic radii as one moves from top to bottom within a group?
The atomic radius increases from top to bottom within a group.
How does the atomic radius change from top to bottom in a group 1 and 2 in the periodic table?
Going down and to the left on the periodic table, atomic radius increases. Therefore, the smallest atomic radius is that of Helium (He), and the largest is that of Francium (Fr). Coincidentally, these are also the most and least reactive elements.
How does atomic number change from top to bottom?
As you move from top to bottom within a group in the periodic table, the atomic number increases sequentially. This is because each element has a unique number of protons in its nucleus, which defines its atomic number. Consequently, as you go down a group, each subsequent element has one more proton than the element above it, leading to a higher atomic number. Additionally, this increase in atomic number is associated with an increase in electron shells, resulting in larger atomic size.
What happens to ionization energy as atomic Number increases within a group?
Ionization energy generally decreases as atomic number increases within a group. This is because the distance between the outermost electron and the nucleus increases, resulting in weaker attraction and lower energy required to remove the electron.
What is the process that results in the increase of atomic number?
The process that results in the increase of atomic number is nuclear fusion. This occurs when two atomic nuclei combine to form a heavier nucleus, leading to an increase in atomic number. Nuclear fusion is the process that powers the sun and other stars.
What physical trends for atomic number versus covalent radius?
As the atomic number increases within a period (row) on the periodic table, the covalent radius generally decreases due to increasing nuclear charge pulling the electrons closer to the nucleus. Within a group (column), as the atomic number increases, the covalent radius tends to increase since new electron shells are being added, leading to a larger atomic size.
What happens to the atomic mass of the element moving from left to right within a period?
The Atomic Mass usually increases, but there are a few exceptions, such as tellurium to iodine.
What are the two variables that affect atomic size within a group?
Increase in positive charge draws electrons closer to the nucleus. Increase in the number of occupied orbitals shields electrons in the highest occupied energy level from the attraction of proteins in the nucleus.
What is the atomic number of the element to the right of the periodic table?
The atomic number increases one-by-one stepping to the right (within a specific period) in the periodic table.
Why does the atomic radius decrease with an increase in atomic numbers within a period?
As the atomic number increases, the number of protons in the nucleus increases or the effective nuclear charge of the nucleus increases. As a result the force exerted by the nucleus on the valence electrons is more or the size of the atom is small.
How does the physical state of a metal change as the atomic number increases?
sticking to increasing at no within group: more soft
What accompanies an increase in atomic number within a specific period?
An increase in atomic number within a specific period corresponds to an increase in the number of protons in the nucleus of the atom. This leads to a higher positive charge, causing the outer electrons to be more strongly attracted to the nucleus. As a result, the atomic size tends to decrease across a period as atomic number increases.
Which of these describes atomic radii as one moves from top to bottom within a group?
The atomic radius increases from top to bottom within a group.
How does the atomic radius change from top to bottom in a group 1 and 2 in the periodic table?
Going down and to the left on the periodic table, atomic radius increases. Therefore, the smallest atomic radius is that of Helium (He), and the largest is that of Francium (Fr). Coincidentally, these are also the most and least reactive elements.
How does an atom get its atomic number?
An atom's atomic number is the number of protons within the single atom of an element
