How Many Ion Does The Element Boron Has?

Svetradugi [14.3K]

Boron's atomic number is 5, so for its 5 protons, it should have 5 electrons if it's neutral.

To make it an ion, Boron's charge would have to be negative or positive. It could lose one electron to have a charge of +1, gain an electron to be -1 ion.

Ions aren't at specific number. So the answer depends on Boron's tendency to gain or lose electrons.

Answer:

Whether matter exists as a solid, liquid or gas is determined by the arrangement of its particles and the strength of attraction between the particles. The three states can be easily distinguished because of their physical properties.

A physical property is a characteristic of matter which can be observed without any chemical change to the matter (shape, volume, colour, smell etc.). A chemical change is one in which new substance are formed.

Explanation:

Solids have a fixed volume and shape. They also vibrate in a fixed position. Ice

Liquids have do not have a fixed shape but a definite volume. They take the shape of their container. They are able to move past each other by allowing the liquid to flow. Water

Gases do not have a fixed shape or volume. Particles take up the space of the container they are in. Particles move freely and rapidly. Water vapour
