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.

Do elements in a group have similar?
Elements in the group have similar chemical properties. This is because their atoms have the same number of electron in the highest occupied energy level.
Are elements with similar properties in the same group or period?
Answer and Explanation: False, elements in the same period (row) have different properties. Elements in the same group (column) have similar properties.
What is true about elements in the same group?
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.
How do you know if elements are similar?
Two different elements are likely to have similar chemical properties when they have the same number of valence electrons. Elements with the same number of valence electrons are found in the same column of the Periodic Table. Elements with the same valence shell are found in the same row on the Periodic Table.
Why don t all the elements in a group have the same properties?
Elements in the same A group do not have identical properties because their valence electrons are in different energy levels.
Why are the elements in the same group or period?
Members of the same group in the table have the same number of electrons in the outermost shells of their atoms and form bonds of the same type. The horizontal rows are called periods.
How are elements with similar properties grouped in the periodic table?
Summary. 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. The horizontal rows on the periodic table are called periods.
Do periods in the periodic table have similar properties?
All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, elements in the same group (column) have similar chemical and physical properties, reflecting the periodic law.
What is true about elements that are in the same column group family?
Each column is called a group. 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.
What has similar physical and chemical properties?
So, we can say that elements in a group have the same physical and chemical properties because their atoms have the same number of valence electrons or same valence shell electronic configuration.
What is common between elements in the same period?
All the elements in same period have same number of shells e.g., all elements in period 3 have 3 shells each i.e., each have same valence shell.
How is the electron structure of the elements in the same group similar?
All the elements in one group have the same number of valence electrons. The valence electrons are those on the energy level the most distant from the nucleus. These valence electrons are those involved in bonding with other atoms to form compounds.
Are elements more similar in groups or periods?
Explanation: The elements of a group have similar chemical properties but in a period they have different chemical properties. This is because the chemicals properties depend on no of valence electrons.
Why do elements in different group show different properties?
Different groups have different valencies. Therefore, elements in different groups show different properties.
What 3 things do elements in the same group have in common?
Answer and Explanation: Elements in the same group have the same number of valence electrons, and therefore have similar levels of reactivity. Every element is made of only one type of atom, and that atom has a unique number of protons, with varying numbers of neutrons and electrons.
Which set of elements has similar properties?
Elements that have similar chemical properties are grouped in columns called groups (or families).
What characteristics do elements in the same group have in common select all that that apply?
What do elements in the same group have in common? They have similar chemical properties and the same number of valence electrons.
What are the characteristics of groups and periods in periodic table?
Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.
How are the elements grouped?
Elements are arranged by reactivity in the periodic table. Elements with similar reactivity are put into the same column or group.
Which group of elements has the most similar chemical properties?
Answer and Explanation: The elements that have the most similar chemical properties are those in the same group, or column of the periodic table. Elements are placed in order of atomic number and end up in vertical groups that have the same number of valence electrons and therefore similar chemical properties.
How are elements similar to those in the same group on the periodic table Quizizz?
How are elements similar to those in the same group on the periodic table? They have the same number of valence electrons.
What are 3 physical properties of metals?
- Corrosion resistance.
- Density.
- Melting point.
- Thermal properties.
- Electrical conductivity.
- Magnetic properties.
What is the difference between family and group in periodic table?
Groups: The vertical column of the periodic table that signifies the number of valence electrons in an element. Periods: The horizontal rows in the periodic table that signify the number of electron shells in an element. Families: Elements that have the same number of valence electrons and therefore similar properties.
What do all elements have in common?
Elements are made of the same types of atoms. Each atom is made of protons, neutrons, and electrons. Protons and neutrons are positioned in the center of the atom called the nucleus, and electrons are found in the outer portions of the atom called energy levels, or electron orbitals.
