What is the charge for calcium ion? 2 What type of ion does calcium form? Calcium, Ca Calcium is also in Group 2. It has two electrons in its outer shell. When these electrons are lost, a calcium ion, Ca 2+, is formed. A calcium ion has the same electronic structure as an argon atom […]
How do muscles get oxygen?
How do muscles get oxygen? Oxygen is supplied to the muscles via red blood cells. Red blood cells carry hemoglobin which oxygen bonds with as the hemoglobin rich blood cells pass through the blood vessels of the lungs. The now oxygen rich blood cells carry that oxygen to the cells that are demanding it, in […]

Can be broken down into two or more components?
Can be broken down into two or more components? Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. mixtures are phisically combined structures that can be seperated into their original components. A chemical substance is composed of one type of atom or […]

What would be the acceleration if the force were doubled?
What would be the acceleration if the force were doubled? It means that if force is constant, as mass is increased, acceleration decreases. resistance to changes in motion (also known as INERTIA.) If the net force on an object is doubled, its acceleration will double If the mass of an object is doubled, the acceleration […]
What happens at an evidence hearing?
What happens at an evidence hearing? The preliminary hearing is like a mini-trial. The prosecution will call witnesses and introduce evidence, and the defense can cross-examine witnesses. If the judge concludes there is probable cause to believe the crime was committed by the defendant, a trial will soon be scheduled. How do you win a […]

Why is hydrogen placed in Group 1 and not 17?
Why is hydrogen placed in Group 1 and not 17? Hydrogen is placed above group in the periodic table because it has ns1 electron configuration like the alkali metals. However, it varies greatly from the alkali metals as it forms cations (H+) more reluctantly than the other alkali metals. Hydrogen has a much smaller electron […]
