The periodic table is a tabular arrangement of chemical elements, organized based on their atomic number, electron configuration, and recurring chemical properties.
What are periods in the periodic table?
Periods are the horizontal rows in the periodic table. There are 7 periods in total.
What are groups (families) in the periodic table?
Groups, also known as families, are the vertical columns in the periodic table. Elements in the same group share similar chemical properties.
What is atomic number?
Atomic number is the number of protons found in the nucleus of an atom. It determines the element's position in the periodic table.
What is atomic radius?
Atomic radius refers to the size of an atom. It increases as you move down a group and decreases as you move across a period in the periodic table.
What is ionization energy?
Ionization energy is the amount of energy required to remove an electron from an atom. It generally increases as you move across a period and decreases as you move down a group in the periodic table.
What is electronegativity?
Electronegativity is the measure of an atom's ability to attract a shared pair of electrons towards itself in a chemical bond. It tends to increase from left to right across a period and decrease down a group in the periodic table.
What is the trend of reactivity in the periodic table?
Generally, metals are more reactive as you move down a group in the periodic table, and nonmetals are more reactive as you move towards the top right of the periodic table.
What is the trend of melting and boiling points in the periodic table?
Generally, melting and boiling points increase as you move across a period from left to right in the periodic table.
What are the noble gases?
The noble gases, also known as Group 18 elements, are a family of elements that exhibit low reactivity and are typically found in their pure form in nature. They include helium, neon, argon, krypton, xenon, and radon.
What is the trend of ion size in the periodic table?
Generally, cations (positively charged ions) are smaller than their parent atoms, while anions (negatively charged ions) are larger than their parent atoms.
What is the trend of metallic character in the periodic table?
Metallic character generally increases as you move down a group in the periodic table and decreases as you move across a period from left to right.
What is the trend of valence electrons in the periodic table?
Valence electrons increase as you move across a period from left to right in the periodic table.
What is the trend of metallicity in the periodic table?
Metallicity generally increases as you move down a group in the periodic table and decreases as you move across a period from left to right.
What is the trend of electronegativity in the periodic table?
Generally, electronegativity increases as you move across a period from left to right in the periodic table and decreases as you move down a group.
