What is the electron configuration of a neutral atom of carbon?

Back

The electron configuration of a neutral atom of carbon is 1s² 2s² 2p².

Front

Describe the trend in metallic character as you move from left to right across a period.

Back

The metallic character decreases as you move from left to right across a period.

Front

Explain why elements in the same period have different properties despite having the same number of electron shells.

Back

Elements in the same period have different numbers of valence electrons, which affects their reactivity and properties.

Front

Why do elements in the same group of the periodic table have similar chemical properties?

Back

Elements in the same group have the same number of valence electrons, leading to similar chemical properties.

Front

What is the general trend of ionization energy as you move across a period?

Back

Ionization energy generally increases as you move from left to right across a period.

Front

How does electronegativity change across a period?

Back

Electronegativity generally increases as you move from left to right across a period.

Front

What is the significance of valence electrons in determining an element's chemical behavior?

Back

Valence electrons determine how an element reacts chemically, influencing bonding and reactivity.

Front

What is the relationship between atomic number and the position of an element in the periodic table?

Back

The atomic number indicates the number of protons in an atom and determines the element's position in the periodic table.

Front

How does the atomic radius change as you move down a group in the periodic table?

Back

The atomic radius increases as you move down a group in the periodic table.
