Calcium and potassium are both metals. … Calcium and potassium have a different number of valence electrons. Correct!
Elements within in the same group/family have similar chemical properties
due to the fact that they have the same number of valence electrons.
Do groups have the same properties?
Atoms having the same number will tend to react the same way, and since elements having the same number are arranged in groups,
groups tend to have the same properties
.
Do groups have similar properties?
Elements in the same group have similar properties because
they have the same number of valence electrons in their outermost shell
. Elements in the same period have different properties because the number of valence electrons in their outermost shells differ.
What are similar properties?
Elements within the same period or group
have similar properties.
What property do Li C and F have in common?
The elements Li, C, and F, are all in the period (row) # 2 of the periodic table, and, in consequence, those atoms have two
energy levels
(main quantum number), n = 1 and n = 2, around the nucleus.
How do you know elements are similar?
The easiest way to identify elements with similar chemical properties is
to look at a periodic table
. The periodic table begins by grouping chemicals into the following categories: metals, semimetals, and nonmetals. Most periodic tables will use the same colors to color code the elements into groups with the same…
Which element has properties similar to lithium?
Lithium and
beryllium
are the first elements of Group 1 and 2 respectively exhibit some properties which are different from those of the other members of the respective group. They both show similarity in properties of the second element of the following group.
Which atom is most like H?
- Lithium. Lithium is the lightest metal in the world. …
- Sodium. The element sodium is most well-known for its relation to table salt, which humans use abundantly in food preparation and preservation. …
- Potassium. …
- Rubidium.
Which element is closest to oxygen?
Explanation: Oxygen is in group 16/VIA, which is called the chalcogens, and members of the same group have similar properties.
Sulfur and selenium
are the next two elements in the group, and they react with hydrogen gas (H2) in a manner similar to oxygen.
Why does density increase down the group?
When we move down the group, there is a constant increase in atomic and ionic radii and also the mass of the atoms increases due to increased no. … Hence the increased size or volume is compansated more by mass i.e,
the increase of mass becomes greater
and in overall the density increases down the group.
Is beryllium similar to lithium?
Lithium
and beryllium are the first elements of Group 1 and 2 respectively exhibit some properties which are different from those of the other members of the respective group. They both show similarity in properties of the second element of the following group.
What element has properties like helium?
Group 8A (or VIIIA) of the periodic table are the
noble gases
or inert gases
Which has maximum Catenation property?
Among all elements of
group 16 Sulphur
shows the highest catenation property.
Which gas is highest in universe?
Hydrogen
, most abundant in the universe, is the chemical element with atomic number 1, and an atomic mass of 1.00794 amu, the lightest of all known elements. It exists as a diatomic gas (H2). Hydrogen is the most abundant gas in the universe.
