Answer:

Positively or negatively charged (im not 100% sure but the question says "as they have lost or gained electrons") because atoms that gain electrons are called anions and atoms that lose electrons are called cations. atoms losing electrons are positively charged and atoms gaining electrons are negatively charged.

I'm not sure if this helps a lot but now you know a few things about ions :)

In an ionic compound, the size of the ions affects the internuclear distance (the distance between the centers of adjacent ions)

gregori [183]

Answer:

The correct answer will be " RbF > RbCl > RbBr > Rbl".

Explanation:

The size of the given ions will be:

RbCl:

⇒ 689kJ/mol

RbBr:

⇒ 660kJ/mol

Rbl:

⇒ 630kJ/mol

RbF:

⇒ 785kJ/mol

Now according to the size, the arrangement will be:

⇒ (785kJ/mol) > (689kJ/mol) > (660kJ/mol) >(630kJ/mol)

⇒ RbF > RbCl > RbBr > Rbl

The bond among all opposite charging ions seems to be strongest whenever the ions were indeed small.

A hypothetical substance has a melting point of −10°C and a boiling point of 155°C. If this substance is heated from 2°C to the

likoan [24]

Answer:

Option 3. Specific heat capacity of the liquid

Explanation:

Let's think, the states for the substance.

In -10, substance turns from solid state to liquid, so at 2°C , state is liquid.

We have to take from liquid state at 2°C to 155°C, which is the boiling point.

As the substance doesn't change its state, we only have to apply the specific heat capacity of the liquid.

1. specific heat capacity of the solid → This is used, when the substance is solid.

2. Heat of fusion → Only used when you turn from liquid to solid

4. Heat of vaporization → Used when the substance changes its state from liquid to gas

5. specific heat capacity of the gas → Used when the substance is a gas.

Mkey [24]

Answer:

5 atoms of hydrogen will be found in the products

Explanation:

5 atoms of hydrogen will be found in the products becuase the law of conservation of mass states that mass is neither created nor destroyed in chemical reactions.

What is the symbol of the species with 23 protons and 21 electrons?

9966 [12]

$V^{2+}$ is the symbol of the species with 23 protons and 21 electrons.

Hence, option F is correct.

<h3>What is a proton?</h3>

Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge.

If it has 23 protons, then its proton number (also know as its atomic number) is 23. You can look that symbol up in your periodic table.

If it has 21 electrons then it has a net charge of 23(+) - 21. So we know the ionisation state of the species, and we can record that as a superscript after the symbol for the species.

Hence, $V^{2+}$ is the symbol of the species with 23 protons and 21 electrons.
