What else can I help you with?
Which group of the main group elements contains the largest elements - Atomic Radius?
Group-1 has largest atomic radius. It decreases across a period
What happens to the size of the atoms as you go down this group?
Atomic size decreases as one moves from bottom to top in a group. The elements get smaller because they have less stuff in them.
What do all elements in a group have?
Atomic mass
Do elements in the same group have the same atomic mass?
No.
Consider the group 1A element sodium (atomic number 11) the group 3A element aluminum (atomic number 13) and the group 7A element chlorine (atomic number 17). These elements are in period 3. How are?
This is a consequence of the law of periodicity of chemical elements.
What happens to the atomic size of the elements as on goes from the top to the bottom of a group?
Atomic size decreases as one moves from bottom to top in a group. The elements get smaller because they have less stuff in them.
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
Which group of the main group elements contains the largest elements - Atomic Radius?
Group-1 has largest atomic radius. It decreases across a period
Which group of the main group elements contains the largest elements?
Group 18 (Noble Gases) contains the largest main group elements because they have the highest atomic numbers and largest atomic radii among the main group elements.
What happens to the group 1 elements as you go down the table?
As you go down Group 1 in the periodic table, the reactivity of the elements increases due to the decrease in ionization energy and increase in atomic size. The metals become more reactive with water and air as you move down the group.
What happens to the size of the atoms as you go down this group?
Atomic size decreases as one moves from bottom to top in a group. The elements get smaller because they have less stuff in them.
What do all elements in a group have?
Atomic mass
What are atomic numbers of the elements in group 13?
5,13,31,49,81,113
Do elements in the same group have the same atomic mass?
No.
Do elements in the same group have similar atomic numbers?
Elements in the same group have similar chemical properties but not necessarily similar atomic numbers. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical properties.
Do transition elements follow the same trend of atomic radius as the main group elements?
NO
What happens to the reactivity of elements in groups as the atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
