All group 2 element have same outmost shell (2)
potassium
Diamond
Count the total number of electrons.
Which of these is always true of atoms? protons, electrons AND neutrons are always equal in number they are always bonded to another atom they always have a charge they are always neutral in elements
this mean like of human body
potassium
which valance shell electron configuration of neutral atoms would represent an element most likely to form a 2-ion?
Diamond
Count the total number of electrons.
Atomicity is having atoms. Also the number of atoms in a molecule.

Do to unequal distribution of electronic cloud between two atoms, the both atoms acquire a partial positive atoms, the both atoms acquire a partial positive and negative charge resperctively.
The most abundant element in any organic structure, including the human is hydrogen.
Draw the structure based on the name. Then count the number of times each atom appears in the structure. Alternately, you can determine the formula from the structure - and then count all atoms of each type.
Symbols are used when showing the molecular structure of a substance, for example the molecular structure of water is H2O meaning that it has 2 hydrogen atoms (H) and 1 oxygen atoms (O)
The number of atoms in an element depends on WHAT element AND how much of that element.
