An ocean basin will form in what location, relative to the major tectonic

plates?

A. At plate boundaries where friction occurs

B. In the center of the largest plates

C. On a plate pushed up by another plate,

D. Where two plates pull apart

D.Where two plates pull apart

Explanation:

Ocean basins are like a large sink in the earth's crust, below sea level.  It is formed by the tectonic plates are separated or pull away from each other, forming magma out of the earth's crust.

When this lava cools, a new ocean bed is formed in the hole centre of the emission.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
