Question

What 4 pieces of information would you expect to see for each element on a standard periodic table?

A. Atomic number, symbol, atomic mass, and electron configuration
B. Group number, valence electrons, melting point, and density
C. Number of isotopes, family name, color, and atomic radius
D. Number of valence electrons, number of protons, phase at room temperature, and atomic weight

Answer 1

A standard periodic table includes the atomic number, symbol, atomic mass, and electron configuration for each element.

Step-by-step explanation:

On a standard periodic table, you would expect to see four pieces of information for each element:

1. Atomic number: This represents the number of protons in an atom's nucleus, which defines the element.
2. Symbol: This is a unique abbreviation used to represent each element. For example, C represents carbon.
3. Atomic mass: This is the average mass of all the naturally occurring isotopes of an element.
4. Electron configuration: This describes the arrangement of electrons in an atom's energy levels or shells.
