Atoms are not drawn to scale. Molecules of compounds have atoms of two or more different elements. For example, water (H2O) has three atoms, two hydrogen (H) atoms and one oxygen (O) atom. Methane (CH4), a common greenhouse gas, has five atoms, one of carbon (C) and four of hydrogen (H, see Fig.

Explanation:

1) Is imposible to determine an element from a simple drawing, more information is need or a higher level of details. Also, a "red blob of atoms" sounds like the  description of a molecule (a union of two or more atoms) that may or may not be formed by only one element.

2) There are 92 natural elements, the other ones are synthetic and/or radioactive. You can identify them in the periodic table because their molecular weights are between ( ).

3) False, a molecule is a particular arrangement of atoms that can be from one or more elements. An element is a particular arrangement of atomic particles (neutrons, protons and electrons.)

Draw it draw lewis dot structures for each hypothetical molecule shown below, using the correct number of valence electrons for
soldi70 [24.7K]

The first molecule is a sensible molecule having complete octet of each atom such as C, H and O whereas the second molecule having hydrogen present between the aldehyde and methyl group and thus showing hydrogen is making bond with aldehyde and methyl as well which is not possible because hydrogen only having one electron in its octet due to which it can only form a single bond by sharing its valence electron.

How much energy is required to evaporate grams of water?.
gregori [183]

Answer:

energy known as the latent heat of vaporization is required to break the hydrogen bonds. At 100 °C, 540 calories per gram of water are needed to convert one gram of liquid water to one gram of water vapour under normal pressure.
