Can i get help please

4.)The red dot is a valence electron (negative charge) , the blue dot is a proton (positively charged), the white dot is a neutron (Neutrally charged).

  A.) the atom is carbon, because it has 6 protons in the nucleus

  B.) the atom has 4 valence electrons.

5.) C.) negatively charged ions (because adding negatively charge electrons makes the atom negatively charged)

6.) lithium has 4 neutrons and 3 protons.

carbon has 6 protons and 6 neutrons

Neon has 10 neutrons and 10 protons

Sodium has 11 protons and 12 neutrons

By the way, the atomic number is the same as the number of protons in the atom. You can find the atomic mass by looking at a periodic table or by looking at the internet.

Explanation:

instead of copying and pasting things off of tests or work done on computer which im sure you did, try and read over the question carefully

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
