An element's atomic number is 25. How many protons would an atom of this element have?

1 answer:

7 0

An element's "Atomic number" IS the number of protons
in the nucleus of each atom of the element.

If an element's Atomic number is 25, then it must follow ...
as the night follows the day ... that each atom of this element
has 25 protons in its nucleus. If it has a different number of
protons in its nucleus, then it's an atom of a different element.

How do lone pairs of electrons affect the bond angle differently than electrons shared in a bond?

lubasha [3.4K]

Answer:

Lone pairs cause bond angles to deviate away from the ideal bond angles

Explanation:

Bonded electrons are stabilized and clustered between the bonding electrons meaning they are much closer together. Non-bonding electrons however are not being shared between any atoms which allows them to roam a little further spreading the charge density over a larger space and therefore interfering with what would be an expected bond angle
