Yes, it is easier to remove a core or a valence electron from an atom.

Valence electrons are the furthest from the positive charge (protons) and therefore also appear to be easier to remove than core electrons this signifies that electrons need less energy to transfer out from the atom. Electrons orbit around a nucleus in orbitals.

Quantum mechanics determines these orbitals and the energy required to remove each electron from the atom. Each of these orbitals helps to form an electron shell in the atom. Valence electrons are electrons in an atom's outermost atomic shell that circle the nucleus.

Closer to the nucleus, electrons are in filled orbitals and are referred to as core electrons. This distinction is due to the fact that electric force is an inverse square law. Furthermore, inner shell core electrons have lower energy levels than outer shell valence electrons. This means that electrons in the inner shells can absorb energy and migrate (jump) to the outer shells.

Harlamova29_29 [7]

Given :

Human blood should have around 1.04 kg/L platelets.

A blood sample of 4.01 milliliters is collected from a patient to be analyzed for a platelet count.

To Find :

The expected mass in grams of platelets in the blood sample.

Solution :

1 L of human blood contains 1.04 kg of platelets.

So, amount of platelets is 1 ml blood is :

=\dfrac{1.04}{1000}\ kg\\\\= \dfrac{1.04\times 1000}{1000}\ gram\\\\= 1.04 \ gram

Mass of platelets in 4.01 ml blood is :

m = 1.04\times 4.01\ gram\\\\m = 4.1704\ gram

Hence, this is the required solution.

How did the first DNA formed
blsea [12.9K]
Experiments suggest that organic molecules could have been synthesized in the atmosphere of early Earth and rained down into the oceans. RNA and DNA molecules — the genetic material for all life — are just long chains of simple nucleotides. Replicating molecules evolved and began to undergo natural selection.

Determine how much energy is needed to change 50 g of liquid water at 100°C to steam.
marin [14]

Answer:

Q=113,000J

Explanation:

Hello there!

In this case, since the vaporization process is carried out in order to turn a liquid into a gas due to the addition of heat, we can use the following heat equation involving the heat of vaporization of water or any other substance:

Q=m*\Delta _{vap}H

Thus, since this heat of vaporization for water is 2259.36 J/g, we plug in this amount to obtain the total energy for this process.

Q=50*2259.36 J/g\\\\Q=113,000J

Which is positive due to the necessity of heat.

Regards!
