Crystalline solids must have a specific, orderly arrangement of atoms to be considered so.
Answer:
Lithium has the lowest electronegativity.
Explanation:
Electronegativity measures the tendency of an atom to attract the bonding pair of electrons. As we move left to right in a period, the number of shell remains same but the number of electron increases(negative charge increases. Hence, electronegativity also increases.
As Lithium is the left most element in this period. It has the lowest electronegativity value which is equal to 0.98.
Answer:
a) acceleration
Explanation:
Acceleration is, by definition, the change of an object's velocity.
Mass of the saturn = 5.683 × 10^26 Mass of the mercury = 3.285 × 10^23
