Elements in the same family have similar properties because
they have the same number of valence electrons
. You just studied 9 terms!
Does elements in the same family have similar properties?
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements
have the same number of valence electrons and similar chemical properties
.
What elements have similar properties?
Elements in the same group of the
periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals.
Which property is same in elements of same group?
Elements within the same group have
the same number of electrons in their valence (outermost) shells
, and they have similar electron configurations. They exhibit similar chemical properties.
Each element within a group has
similar physical or chemical properties
because of its atom’s outermost electron shell (most chemical properties are dominated by the orbital location of the outermost electron).
How do you know that potassium K is highly reactive?
The alkali metals, Group 1A, are the most reactive metals
because they have one valence or outer electron
. They lose this electron very easily, forming ions with a charge of +1. … This same strong reactivity because of one valence electron is true of potassium, as well.
What group has the most reactive metals?
Reactivity of Group 1 Elements
Hydrogen is a very reactive gas, and the
alkali metals
are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
What are the two main types of elements?
The elements can also be divided into two main groups,
the metals and the non-metals
. Metals are typically have a metallic sheen (shiny) are malleable (bendable) and conduct electricity. Nonmetals typically do not show these properties.
Is C a nonmetal?
| NUMBER SYMBOL ELEMENT | 6 C Carbon | 7 N Nitrogen | 8 O Oxygen | 9 F Fluorine |
|---|
Which element is most chemically similar 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.
What is the general configuration of S block elements?
The general electronic configuration of s-block elements is
[noble gas]ns1 for alkali metals
and [noble gas] ns2 for alkaline earth metals.
Which element in the group has the highest density?
The element with the highest density in group 1 is
Francium
.
What are the Group 18 elements called?
Noble gas
, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).
What are 3 family names of the periodic table?
- Group 1: alkali metals, or lithium family.
- Group 2: alkaline earth metals, or beryllium family.
- Group 3: the scandium family.
- Group 4: the titanium family.
- Group 5: the vanadium family.
- Group 6: the chromium family.
Which family of elements does not react with oxygen?
Solutions. No,
noble gases
are unreactive with oxygen. Oxygen is mostly unreactive with gold and platinum. When an oxide reacts with water, a metal hydroxide is produced.
