.The Atomic Mass increases
What else can I help you with?
Why does atomic size increase from left to right across a period?
atomic size decreases across a period
What does atomic radius do across a period?
Atomic radius tends to decrease across a period from left to right. This is because as you move across a period, the number of protons in the nucleus increases, leading to an increase in the effective nuclear charge felt by the outermost electrons, which pulls them closer to the nucleus.
What happens when the nuclear charge increases across a period?
As the nuclear charge increases across a period, the number of protons in the nucleus increases. This leads to a stronger attraction between the nucleus and the electrons in the atom, resulting in a greater effective nuclear charge. This can lead to an increase in the atomic size and higher electronegativity across a period.
What happens as periods increase on the periodic table?
As you move across a period on the periodic table, the number of protons increases, which increases the atomic number. This results in a greater positive charge in the nucleus, leading to an increase in the attraction between the nucleus and the electrons in the outer energy levels. This trend generally results in smaller atomic size and higher electronegativity as you move across a period.
What is the trend in atomic size across the period from sodium to argon?
Atomic size decreases across the period from sodium to argon due to increasing nuclear charge, which attracts the outermost electrons more strongly, pulling them closer to the nucleus. This results in a smaller atomic size as you move from left to right across the period.
What happens to the atomic number as you go across a period?
The atomic number increases as one go across a period.
What happens to the reactivity of elements in group a as atomic number increase across a period?
they do becaused they want to do it
How does the atomic number change in a period?
When going left to right across a period, the atomic number of element increases.
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.
When moving across a period in the periodic table?
The atomic number increases
What stays the same across a period on the periodic table?
the atomic number.
What do you noticed about the atomic number in each period?
Atomic number increases from left to right across a period.
An increase in the atomic number the atomic radius moving from left to right across a period.?
decreases
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.
Why does atomic size increase from left to right across a period?
atomic size decreases across a period
Elements across a series have same number of?
Elements across a series have the same number of attributes or characteristics.
What happens to the atomic mass as you go across a period from left to right?
It generally goes up, though there are exceptions.
