need more help with science homework please?? there are alot of questions! LOL :(?

Question

1. name the 3 types of particles found in atoms.

2. which two particles are only found in the nucleus of an atom?

3. many everyday substances, such as oxygen, gold and aluminium, are elements. other substances such as water and sugar are not. explain what this means in terms of the atoms in them.

Answers

1) Electrons, Protons and Neutrons are the three types of particles.

2) Only protons and neutrons are found in nucleus.

3) Water and sugar etc. are chemical compounds of two or more atoms. Water is composed of 2 atoms of hydrogen and 1 atom of oxygen. The cluster of atoms is called a molecule and the atoms are in definite proportions.

Answer 2

1. the three types of of subatomic particles are protons, electrons and nuetrons.
2. The two particles found in the nucleus of the atom are nuetrons and protons.
3. Oxygen and gold are elements and are made of only one specific type of atom. Water on the other hand (and sugar too) are made out of 2 or three different elements.
ex-Water is 2 hydrogen atoms and once oxygen
Gold-gold atoms

Answer 3

1. three particles are a) proton(+ve charge)
b)neutron
c)electron(-ve charge)

2. particles in nucleus--> a) proton b) neutron

3. See Oxygen, Gold etc are elements but in our everyday life we dont interect with these elements.The Oxygen we breath is compound which is made up combination of similar oxygen elements to form a stable compound [ o +o -> o2] here o is oxygen element and o2 is oxygen molucle. Where as water is a compound of different elements i.e. oxygen + Hydrogen & same for sugar it is a compound of Carbon + Hydrogen + Oxygen

Answer 4

1. electrons, protons, and neutrons.

2. protons and neutrons

3. water and sugar are examples of compounds... they are composed of several atoms of different elements...
