What else can I help you with?
What happens to the atomic radius as you go across a period?
It decreases as you move from left to right because there is an increase in positive charge in the nucleus as you go from left-to-right. Each time you go over an element it has one more electron and proton added to the principal energy level, so the nucleus pull increases and it holds the valence electron in tighter.
What happens to the atomic number as you go down the group?
The atomic number increases as you go down a group on the periodic table. This is because each element in a group has one more electron and proton than the element above it, leading to an increase in atomic number.
How does atomic radius vary down a group?
Atomic radius increases down a group on the periodic table because with each additional period an energy level is added.
What statement accurately compares the trends in atomic number and atomic mass in the period gave?
In a period of the periodic table, atomic number increases sequentially from left to right as protons are added to the nucleus of each successive element. Atomic mass typically increases as well, although it does not always correlate directly due to the varying number of neutrons in isotopes. While atomic number defines the identity of an element, atomic mass reflects both protons and neutrons, leading to a generally increasing trend in mass alongside the atomic number across a period.
What does the sequence in each period represent in relation to electrons?
The sequence in each period represents in relation to electrons is that as you look from left to right on the periodic table, you see a pattern; an increase of the atomic number. The number of electrons equals the number of protons, and the number of protons equals the atomic number.
What happens in most cases to the atomic mass as you go from left to right in each period?
it increases
What do you noticed about the atomic number in each period?
Atomic number increases from left to right across a period.
What happens to the atomic radius as you go across a period?
It decreases as you move from left to right because there is an increase in positive charge in the nucleus as you go from left-to-right. Each time you go over an element it has one more electron and proton added to the principal energy level, so the nucleus pull increases and it holds the valence electron in tighter.
What happens to the atomic number as you go down the group?
The atomic number increases as you go down a group on the periodic table. This is because each element in a group has one more electron and proton than the element above it, leading to an increase in atomic number.
When looking across a period of the periodic table from left to right when happens to the atomic number and electronegativity?
As you move across a period from left to right in the periodic table, the atomic number of the elements increases by one with each element. Electronegativity also increases across a period from left to right due to the increasing nuclear charge and decreasing atomic radius, which results in stronger pull on electrons.
What are the general characteristics of natural law for each period?
laws & legal issues
How does atomic radius vary down a group?
Atomic radius increases down a group on the periodic table because with each additional period an energy level is added.
What is the relationship of atomic radii for each pair of species shown below?
The relationship of atomic radii for each pair of species shown below is that the atomic radius increases as you move down a group on the periodic table and decreases as you move across a period from left to right.
What is the periodic trend for atomic size from top to bottom in a group?
Atomic size generally increases from top to bottom within a group on the periodic table. This is because each successive element has an additional energy level of electrons, leading to increased electron-electron repulsion and an overall increase in atomic size.
What relationship does an atomic number have to the periodic table?
The atomic symbols in a modern periodic table are usually arranged so that, from left to right, each atom has an atomic number higher by 1 than the atom immediately to the left, and the first atom in a period has an atomic number higher by 1 than the rightmost atom in the period immediately above.
How do atomic numbers and atomic masses increase in the periodic table?
Atomic numbers increase from left to right across a period on the periodic table. This is because each element in a period has one more proton in its nucleus compared to the element before it. Atomic masses generally increase from left to right as well, but there may be deviations due to isotopes or other factors. Within a group or column, atomic numbers and atomic masses increase from top to bottom as each successive element has more electrons and neutrons than the one above it.
As you move across a period of the periodic table from left to right what happens to the number of protons contained by each element?
The number of protons contained by each element increases by one as you move across a period of the periodic table from left to right. This is because each element in a period has one more proton in its nucleus than the element before it.
