Anything that has mass and takes up space
Answer: There are two elements actually and those elements are Carbon and Silicon
Explanation:Plz mark brainliest if im right
VESPR (<span>Valence Shell Electron Pair Repulsion) is used to determine the shape of the molecules based on their number of electron pairs and how they interact with each other via repulsion. Different numver of electron pairs will form different shapes, e.g. 0 pairs = linear, 1 = pyramidal...</span>
Generally (but far from universally), the elements within a group have similar characteristics. Antimony, nitrogen, and arsenic are all part of the same group as phosphorous (the pnictogens, or group 5A). Oxygen is not in this group, but rather in an adjacent group (the chalcogens, or group 6A). Thus, the answer here should be oxygen.
That said, there can be very significant differences in characteristics among the elements within a group, and that is certainly the case here. For example, free nitrogen exists predominantly as a molecular gas (N₂) and makes up about 78% of the atmosphere we breathe. Elemental arsenic (As), while in the same group as nitrogen, is naturally found in the solid state and is poisonous to humans (arsenic is sometimes included among the toxic heavy metals, although it’s technically a metalloid).
Answer is D, they are compressible
