What else can I help you with?
What sub atomic particle increasesas you move to the right across the periodic table?
Electronegativity increases as you move across the periodic table from left to right.
When moving across a period in the periodic table?
The atomic number increases
What happens to the atomic mass number as you move across the periodic table?
The atomic mass number generally increases as you move across the periodic table from left to right. This is because the number of protons in the nucleus increases as you move to elements with higher atomic numbers.
How much does the atomic number increase bye as you go across a row on the periodic table?
The atomic number increases by one as you go across a row on the periodic table. Each element in the row has one more proton in its nucleus than the previous element, which is reflected in the increase in atomic number. This trend continues across each row of the periodic table.
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 sub-atomic particle increases when you read the periodic table from left to right?
Protons increases by one as we move from one element to other, left to right.
How much does the number increase by as you go across a row on the periodic table?
The atomic number increases by 1 as one go across a row on periodic table. The elements are arranged in order of increasing atomic number.
What increases as you move right across a period in the periodic table?
Atomic number, ionization energy and electronegativity
WHAT BEST STATES THE TREND IN ATOMIC RADIUS ACROSS THE PERIODIC TABLE?
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
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.
How does atomic radius vary in group and in period on periodic table?
Down a period the atomic radius increases as the number of shells (or energy levels) increases. Across a period the atomic radius decreases as the effective nuclear charge increases.
What changes from left to right as you move through the groups of periodic table?
Atomic radius increases across a group. Metallic character also increases.
