4. Why do elements in the same family generally have similar properties?

1 answer:

7 0

Because they have the same number of electrons in the outer shell, they have the same reactivity (they all want to lose/gain a certain amount of electrons to have a full shell of 8), so they have the similar melting, boiling points etc because they all undergo very similar reactions to certain factors so have similar outcomes

How heat moves from one end of a solid to another

pantera1 [17]

In conduction, the thermal energy of a particle is transferred to other particles throughout the solid. The particles with more energy are transferred to those with less.

Why do think there is often only a short amount of time to evacuate an area before an earthquake?

Blababa [14]

Earthquakes can cause massive distruction that can even cause death. In order to prevent any damage done to you, you must leave the scene immediatly, especially since an earthquake can tear down houses and buildings

Is matter continuous and therefore has no finer structure or is it discontinuous and thus made or tiny particles

Marta_Voda [28]

Matter is discontinuous, and it is made of tiny particles called atoms

Explanation:

Matter is not a continuous structure, but it consists of tiny particles called atoms.

An atom consists of three types of particles:

Proton: the proton is in the nucleus of the atom. it has a positive electric charge of $+1.6\cdot 10^{-19}C$ (also called fundamental charge). Its mass is $1.67\cdot 10^{-27}kg$ .

Neutron: the neutron is also in the nucleus of the atom, but it has no electric charge. Its mass is similar to the mass of the proton (slightly heavier). Neutrons and protons are held together in the nucleus through the strong nuclear force.

Electron: electrons are found in a "cloud" outside the nucleus. Electron has negative electric charge equal to $-1.6\cdot 10^{-19}C$ . Its mass is much approximately 1800 times smaller than that of the proton, so it is considered as negligible.
