Answer:

The object with the greatest density

Explanation:

The object that will have the greatest mass from the given choices is the one with greatest density.

Density is the mass per unit volume of a substance;

Density = $\frac{mass}{volume}$

We can see that density is directly proportional to the mass and inversely proportional to the volume.

The more the mass and the lesser the volume, the higher the density.

So, since the volume is the same, and mass is directly proportional to density, the object having the highest density will have the greatest mass.

Write the charge and full ground-state electron configuration of the monatomic ion most likely to be formed by each:

Sladkaya [172]

Answer:

Part A:

Charge is $P^{3-}$

Configuration is $1s^2 2s^22p^63s^23p^6$

Part B:

Charge is $Mg^{2+}$

Configuration is $1s^2 2s^22p^6$

Part C:

Charge is $Se^{2-}$

Configuration is $1s^2 2s^22p^63s^23p^64s^23d^{10}4p^6$

Explanation:

Monatomic ions:

These ions consist of only one atom. If they have more than one atom then they are poly atomic ions.

Examples of Mono Atomic ions: $Na^+, Cl^-, Ca^2^+$

Part A:

For P:

Phosphorous (P) has 15 electrons so it require 3 more electrons to stabilize itself.

Charge is $P^{3-}$

Full ground-state electron configuration of the mono atomic ion:

$1s^2 2s^22p^63s^23p^6$

Part B:

For Mg:

Magnesium (Mg) has 12 electrons so it requires 2 electrons to lose to achieve stable configuration.

Charge is $Mg^{2+}$

Full ground-state electron configuration of the mono atomic ion:

$1s^2 2s^22p^6$

Part C:

For Se:

Selenium (Se) has 34 electrons and requires two electrons to be stable.

Charge is $Se^{2-}$

Full ground-state electron configuration of the mono atomic ion:

$1s^2 2s^22p^63s^23p^64s^23d^{10}4p^6$

What causes water to increase in density?

murzikaleks [220]

Explanation:

temperature changes affect seawater density as water cools its density increases. As water cools H2O molecules pack more closely together because the molecules are vibrating less at low temperatures and take up less volume. The same number of water molecules in smaller volume results higher density

Which of the following is the best definition of radiation?

mafiozo [28]

Answer: Option (D) is the correct answer.

Explanation:

When heat or energy is transferred through the space in the form of waves or through a material medium then it is know as radiation.

For example, when we take Sun bath then our body gets warm due to solar radiation.

For transfer of heat through radiation it is not necessary that the objects have to in contact with each other.

Thus, we can conclude that out of the given options, the transmission of heat without any contact.
