Since Group 2 alkali earth metals have 2 valence electrons, they tend to lose those 2 when forming ionic bonds. And the Loss of Electrons = Oxidation (L.E.O. for short). Therefore this group, including Mg and Ca, have an oxidation of [+2].
So the correct answer is C) +2

Many of the men may believe that they are fair and unbiased against women.

Many of the women may already believe that they face biases.

<h3>What is confirmation bias ?</h3>

The propensity to seek for, understand, favor, and remember information that supports or confirms one's preexisting opinions or values is known as confirmation bias. People exhibit this bias when they choose facts that support their opinions while rejecting those that contradict them or when they interpret ambiguous facts as supporting their preexisting beliefs. Although confirmation bias cannot be completely avoided, it can be controlled, for instance, by critical thinking education and training.

Confirmation bias has been linked to poor decisions in the scientific, organizational, financial, and political spheres. These biases can preserve or reinforce views in the face of contradictory data and contribute to overconfidence in personal opinions.

If you have a mass of 60 kg on earth, what is your weight in newtons?
AnnyKZ [126]
To calculate your weight in Newton's simply use the following equation to solve for the weight.

Fg = m • g
Fg = 60 kg • 9.81 m/s^2
Fg = 588.6 kgm/s^2

Fg = 588.6 N.

Acceleration due to gravity on earth is 9.81 m/s ^2.

The atom is one of the basic units of matter. Which part of the atom mostly determines the size of the atom?
dedylja [7]

Answer:

Atomic size is the distance from the nucleus to the valence shell where the valence electrons are located. The separation that occurs because electrons have the same charge. The number of protons in the nucleus. The core electrons in an atom interfere with the attraction of the nucleus for the outermost electrons.
