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 do all elements in a group have?
Atomic mass
Do elements in the same group have the same atomic mass?
No.
Describe the Reactivity of group 1 element varies with increasing atomic number?
describe how the reactivity of group1 elements and group 7 elements varies with increasing atomic number
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.
Is argon a rare earth element?
No, argon is not part of the group known as rare earth elements. Rare earth elements are a series of 15 elements known as the lanthanides, (atomic numbers 57 through 71 - lanthanum through lutetium) and include yttrium (atomic number 39) and scandium (atomic number 21). They fall under the category of metals. Argon is a gas.
Which group of the main group elements contains the largest elements - Atomic Radius?
Group-1 has largest atomic radius. It decreases across a period
Where are lanthanides located?
The lanthanide series comprises the fifteen metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium. These fifteen elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements. In the Group 3, Period 6 slot, After Barium and prior to Hafnium.
What do all elements in a group have?
Atomic mass
How are period and group trends in atomic radii are related to electron configuration?
The atomic radius decreases along the elements across a period. Along a group, there is an increment in the atomic radius of corresponding elements.
What is the name of the elements with atomic numbers 90 through 103?
The elements are called Actinides. They are placed at the bottom of periodic table. These elements have different properties.These elements are in the f group of the periodic table. Elements from Ac-Lr belong to this group. These are called Actinides.
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?
No. Elements in the same group have same number of valence electrons.
Describe the Reactivity of group 1 element varies with increasing atomic number?
describe how the reactivity of group1 elements and group 7 elements varies with increasing atomic number
Do transition elements follow the same trend of atomic radius as the main group elements?
NO
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.
