Elements in the same group have
the same number of valence electrons
, and therefore have same levels of reactivity.
What do elements in the same group have in common quizlet?
What do elements in the same group have in common? They
have similar chemical properties and the same number of valence electrons
. … They are extremely reactive because they only need one more electron to have all of their energy levels filled. They are most reactive with group 1, the alkali metals.
What two things do elements in the same group have in common?
The elements in each group have
the same number of valence electrons
. As a result, elements in the same group often display similar properties and reactivity.
Do elements in the same group have similar 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).
Why do elements in the same group have similar?
The elements in a given group possesses
similar electronic configuration
, as the number of electrons in the respective outermost shells is the same. So, they have similar physical and chemical properties.
What 3 things elements in the same group have in common?
The elements in each group have
the same number of electrons in the outer orbital
. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its outer shell.
What is the most active element in Group 17?
The most active element in Group 17 is
FLUORINE
.
Which group of element is the most unreactive Why?
The group 0 elements are found on the right hand side of the periodic table. They are called the
noble gases
because they are very unreactive.
What group S contain the most highly reactive elements?
All the other elements in group 1 are alkali metals. They are the most reactive of all metals, and along with the elements in
group 17
, the most reactive elements. Because alkali metals are so reactive, they are only found in nature combined with other elements.
What are the elements in the first group called?
Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What is Group 11 called?
The Group 11 is composed of copper (Cu), silver (Ag), and gold (Au). Silver and Au belong to the so-called
noble metals
.
What element is the most nonmetallic?
The most non metallic element is
fluorine
.
Which is the largest atom in group 4a?
The heaviest element in group 14,
lead
, is such a soft and malleable metal that the ancient Romans used thin lead foils as writing tablets, as well as lead cookware and lead pipes for plumbing. (Recall that the atomic symbols for tin and lead come from their Latin names: Sn for stannum and Pb for plumbum.)
What happens to atomic size as we move from top to bottom in a group?
(a) On going down in a group of the periodic table, the atomic size increases. When we move from top to bottom in a group,
a new shell of electrons is added to the atoms at every step
due to which the size of atom increases.
Why are members of Group 1 called alkali metals?
The Group 1 elements are called the alkali metals. … All the Group 1 elements are very reactive . They must be stored under oil to keep air and water away from them. Group 1 elements
form alkaline solutions when they react with water
, which is why they are called alkali metals.
Why do we classify elements?
Due to discovery of different elements, it was difficult to organize the information and properties of the elements
, so there was a strong need to find some pattern in the properties of different elements so that they can be grouped. That’s why we classify elements.
