The number of protons in an atom is the atom's atomic number.
In a neutral atom the number of protons is equal to the number of electrons.
There is possibility of losing the electrons, but the number of protons are not loosed, except in nuclear chemistry.
So the number of protons is equal to the atom's atomic number.

Using the evidence provided, generate a pattern that describes the chemical reactivity of metals.
Afina-wow [57]

Answer:

B)As you go from left to right, reactivity of metals increases. As you go down in a group, reactivity of metals decreases.

Explanation:

reactivity of metals can be explained as how it can easily lose electron, i.e oxidize as well as reaction with non-metals.

There are factors that influence the reactivity of metals such as

1)atomic radius

2)nuclear charge

3)shielding effect

4) The sublevel arrangement of electrons

In the periodic table,the group 1, known as alkali metals, are the most reactive metals

Therefore, as we from left to right, reactivity of metals increases. As we move down in a group, reactivity of metals decreases.

mart [117]

It takes so much heat to melt ice or evaporate water because extra energy is required to break the hydrogen bonds between water molecules.

<h3>Hydrogen bond</h3>

Hydrogen bonding is an electrostatic force of attraction between a hydrogen atom found between a pair of other atoms having a high affinity for electrons.

Hydrogen bonds cause water to be exceptionally attracted to each other creating cohesion.

It takes so much heat to melt ice or evaporate water because extra energy is required to break the hydrogen bonds between water molecules.
