Periodic table trends

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

Which element has the highest electronegativity in the periodic table?

Back

Fluorine (F) has the highest electronegativity in the periodic table.

Front

What is the significance of an element's group number in the periodic table?

Back

The group number indicates the number of valence electrons in the outer shell of the elements in that group, which influences their chemical properties.

Front

How many protons does an element in group 17 have?

Back

An element in group 17 has 17 protons.

Front

What is the relationship between elements in the same group?

Back

Elements in the same group have similar physical and chemical properties due to having the same number of valence electrons.

Front

What is the electron configuration of an element with atomic number 2?

Back

The electron configuration of an element with atomic number 2 (Helium) is 1s².

Front

How can you determine the electronegativity trend in the periodic table?

Back

Electronegativity generally increases across a period from left to right and decreases down a group.

Front

What does the term 'periodic trends' refer to?

Back

Periodic trends refer to the predictable patterns in the properties of elements as you move across or down the periodic table.

Front

Which element has an electron structure most similar to that of element X with atomic number 2?

Back

Element Y with atomic number 2 also has a similar electron structure.

Front

What is the general trend for atomic radius in the periodic table?

Back

Atomic radius decreases across a period from left to right and increases down a group.
