If an atom has a different number of protons, it is a(n)_________
3)What is the noble gas configuration and wat does it imply?
4)How are metals and non metals separated on the periodic table?
5) is the following Fission of Fusion?

b-Light nuclei combine, release lots of energy, from larger nucleus.
c-Used in nuclear power plants.
d-Power the sun and starts.

i will post more while yall ancer these. TX!!!

6) Is all nuclear radiation dangerous? Explain.

----> if you know a way that i could use to help me memorize this info... please post as well. more qestions are coming tx for ancering!!!

13) Tell if the following are acid, base, or salt:
a-HCI
b-H2SO4
c-NaOH
d-taste bitter

h-ph less than 7
i. pH greater than 7
j. conducts electricity
k. reacts with metals
I. turns litmus blue
m. turns litmus red
n. has more H+ ions than 0H- ions

(sinse that was an ultra long question i think i will stop here and continue on a new list) keep ansering!!!

14) the force of gravity acting on an object is defined as_______.

15)Whenever a force movies an object through a distance in the same direction as the force, _______ is done on the object.

16) if you push against a wall and the wall does not move, have you done any work???

17) how much work is done when a 60 N object is moved 1.5 m by 20 N force? (could you please also give me the formula for work, in your anser)

18) Define waves.

19) Define Frequency.

20)wat is the forumla for finding frequency?

21)Define amplitude.

22) Sound is a _______wave.

23) Seismic ("p") waves are ________waves.

Answer 1

1) because there is the same amount of protons and electrons
2) a) Ion
b) Isotope
c) New Element
3) The outer most electron shell is full, inert, ie noble men dont interact with common People
4)divided by the stair chase "semi metal" some tables show them in different colours
5) a) Fission
b) Fussion
c) Fission
d) Fussion

Answer 2

1)because there is the same number of electrons and protons… ( same number of negative and positive charges)
2)ion then isotope then New element
3)PV=nRt?
4)Dunno
5)A: fission; B: fusion..C:fission..D:fission and fusion

i think i'm wasting my time in an offhand way...
anyway...good luck

Answer 3

1) same # of protons and electrons
2) ion
isotope
new element
3) ---
4) staircase
5) ---
