atoms

Question 1

what particles are atoms made out of?

Answer 1

protons, neutrons, electrons

Question 2

what various masses do these particles have?

how do you figure out the atomic mass?

Answer 2

protons- 1, neutrons-1, electrons- 0(insignificant)

number of protons + neutrons = atomic mass

Question 3

what is in the nucleus of an atom?

Answer 3

protons and neutrons

Question 4

what is the atomic number(proton number)?

Answer 4

Number of protons an atom has

Question 5

how many electrons does an atom have?

Answer 5

the same number as the number of proton an atom has

Question 6

how do you figure out how many neutrons an atom has?

Answer 6

take away the relative mass ( the top number) - atomic(proton number on the bottom ) number

Question 7

how are chemical bonds formed?

Answer 7

Atoms sharing, gaining or losing electrons

Question 8

what determines which element an atom is?

Answer 8

the proton number

Question 9

what are isotopes?

Answer 9

isotopes are atoms with the same number of protons (same element) but they have different number of neutrons- subsequently different atomic mass.

Question 10

what are ions?

Answer 10

ions are charged atoms which are created when an atom loses or gains electrons. by gaining electrons a negative is created and by losing electrons a positive ion is created

Question 11

what is compound?

Answer 11

substances formed by two or more atoms joined together by a bond
