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 when a mixture of oil and water are left to stand?
It will separate and the oil will float to the top, as it is lighter than water.
What happens to the first ionization energy of the elements as a period is crossed?
Moving from left to right across a period, the first ionization energy increases because it becomes increasingly difficult to remove an electron.
What happens to the atomic radius when you go from left to right on the periodic table of elements?
The atomic radius decrease, with several exceptions in periods 6 and 5.
Ionization energies tend to do what from left to right across a period?
increase from left to right across a period.
Does colloid sets in when left for along time?
It depends what kind of colloid for example milk will not, it is a colloid but it doesn't set... Others may just depending on what kind your talking about
What happens to copper if it is left in water for a long period of time?
It turns blue.
What happens in most cases to the atomic mass as you go from left to right in each period?
it increases
What happens to the energy levels are you move from left to right on the periodic table?
The energy level generally remains the same in a period (as we move from left to right). Down a period, the energy level increases.
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 when a mixture of oil and water are left to stand?
It will separate and the oil will float to the top, as it is lighter than water.
What happens to salt water when it is left out over a period of time?
the water evaporates, leaving the salt behind.
What happens to the size of an atom moving from left to right through a period why does this happen?
Atomic radius decreases from left to right due to increase of protons
What happens to the atomic mass as you go across a period from left to right?
It generally goes up, though there are exceptions.
What happens if a right handed is forced to use the left hand?
then they will learn how to use their left hand and after a long period of time forget how to use their right hand.
What happens to the first ionization energy of the elements as a period is crossed?
Moving from left to right across a period, the first ionization energy increases because it becomes increasingly difficult to remove an electron.
When looking across a period of the periodic table from left to right when happens to the atomic number and electronegativity?
As you move from the left to right, the atomic number increases. Also, the electronegativity increases.
