What happens to the properties of elements across any periodic of the table?
Across any period, the properties of elements gradually change. This gradual change is called a periodic trend.
What happens to the reactivity of left to right across the periodic table?
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
How does reading across a period the periodic table compare with reading down a group of the table?
Periods (across the Periodic Table) have increasing Atomic Mass. Groups (down the table) have similar properties and reactive natures.
A row across the periodic table is called a?

What are patterns in the periodic table?
Patterns in the periodic table include the periodicity of atomic properties such as atomic number, atomic mass, electronegativity, and ionization energy. The table is organized by increasing atomic number and elements with similar properties are grouped together in columns called groups or families. Trends in properties of elements within a period or group can be observed based on their position in the periodic table.
What is a period in the periodic table and how does it relate to the organization of elements?
A period in the periodic table is a horizontal row of elements that share similar chemical properties. Each period represents the number of electron shells in an atom. The organization of elements into periods helps to show trends in properties as you move across the table from left to right.
Why is a row in a periodic table called a period?
A row in the periodic table is called a period because elements within the same row have similar chemical properties which repeat in a periodic manner. As you move across a period, the number of protons and electrons increases, leading to similar trends in the elements' properties.
What is the most important in determining the periodic trends across a period?
The nuclear charge, or number of protons in the nucleus, is the most important factor in determining periodic trends across a period. As you move across a period, the nuclear charge increases, leading to stronger attraction between the nucleus and the electrons, affecting properties such as atomic size and ionization energy.
What happens to the state of matters you go across the periodic table?
Across the period (left to right), the elements tend to change from solids (metals) to gases (non metals).
What to atomic properties have an increasing trend as you move across the periodic table?
As we move across a period, electronegativity increases. Ionization enthalpy also increases because of increasing nuclear charge.
A row of elements across the periodic table is an?
A row of elements across the periodic table is called a period. Periods represent the number of electron shells in an atom.
Why are elemental properties periodic?
Elemental properties are periodic because they are determined by the number of protons in the nucleus of an atom, which increases systematically as you move across a period. This leads to a repeating pattern of properties such as electronegativity, ionization energy, and atomic size.
