What are the characteristics of groups?
Instead, a primary characteristic of groups is that members of a group are dependent on one another for the group to maintain its existence and achieve its goals….Group Communication Then
- Synergy.
- Common Goals.
- Shared Norms.
- Cohesiveness.
What are five characteristics of a group on the periodic table?
Group= Total number of valence electrons….1. Atomic size:
- Atomic size: The atomic size decreases from left to right in a period.
- Valence Electrons: The number of V.Es increases from 1 to 8 along the period.
- Valency:
- Electropositivity & reactivity of Metals:
- Electronegativity & reactivity of non-metals:
What are the characteristics of groups in a periodic table?
CHARACTERISTICS OF GROUPS: All the elements of a group of the periodic table have the same number of valence electrons. For example, group I elements: Li, Na, K etc., all have a valency of . Elements of group 17: Cl, Br, I etc., all have valency of .
What does the group show in periodic table?
The columns of the table represent groups, or families, of elements. The elements in a group often look and behave similarly, because they have the same number of electrons in their outermost shell — the face they show to the world.
What are the characteristics of Group 4 on the periodic table?
They have a high affinity for oxygen. They mainly have +4 oxidation state which is mainly due to the loss of all four ns2(n − 1)d2 valence electrons. The group 4 elements become denser, higher melting, and more electropositive as we move down the column in the periodic table.
Which period is the longest group in the modern periodic table?
Modern periodic table is divided into 7 periods and 18 groups. Group 1(H, Li, Na, K, Rb, Cs, Fr) is the longest group in the periodic table. The first group is called the alkali metals group….Thank you.

Which is longest period?
The sixth period is called the longest period because it has maximum 32 elements.
Which period in periodic table is incomplete?
The seventh period of the Periodic Table is incomplete. The only incompleteness (a few years ago) was the IUPAC confirming and naming of the elements with atomic number 113, 115, 117 and 118.
Which is the first longest period in periodic table?
There follow two periods of 18 elements each: the first long period, from potassium 19, to krypton, 36; and the second long period, from rubidium, 37, to xenon, 54.
Which two periods are known as short periods?
The first period is the shortest period containing only 2 elements. The second and third periods are short periods. The population of each short period is eight elements. The fourth and fifth periods are long periods and contain 18 elements each.
What is Period 2 in the periodic table?
The second period contains the elements lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon. In a quantum mechanical description of atomic structure, this period corresponds to the filling of the second (n = 2) shell, more specifically its 2s and 2p subshells.
