describe how changing the particles changed the atom
Changing the particles changes the atoms by converting it to a new substance through bond change.
During a chemical reaction changes occurs in the atoms of an element due to the formation or breaking of bonds.
There is either loss or gain or sharing of atoms between two elements reacting together.
Bonds between atoms break and new ones form and energy is either given out or taken in.
This type of reaction leads to the formation of new substances made up of a new combination of atoms and a different configuration of electrons.
Therefore, because various changes occurs during a chemical reaction, changing the particles changes the atoms by converting it to a new substance through bond change.

What is the mass of an atom with 7 protons, and 7 neutrons?
Answer:
Explanation:
Nitrogen has an atomic number of 7 (Z=7) because it has 7 protons in its nucleus. Some nitrogen atoms have an atomic mass number of 15 (A=15). A is the number of neutrons plus protons in the nucleus. However, we already know that there are 7 protons.

does water in a glass have mass
Answer:
A glass of water, or 200 grams of water, therefore contains 6.6855 × 1024 water molecules. The total mass of the hydrosphere is about 1.4 × 1024 grams, and thus the total hydrosphere contains about 7 × 1021 glasses of water (with 200 grams of water in each).
Explanation:
Answer:
Just like solids, liquids also have their own characteristic density. ... Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. The density of water is 1 gram per cubic centimeter. The density of a substance is the same regardless of the size of the sample.
Matter is generally defined as any thing that has mass and occupies spaces. Matter is generally divided into three categories ; solid, liquid and gas. Water is a liquid, water has does have molecules, thus has a mass, and is suspended in an area such as water in glass.
SO YES WATER IN A GLASS HAS MASS :)Hope this helps ~OwO~

For B: the contact force would be the ball being kicked and the non-contact would be the gravity pulling it back to the ground.
For C: A hiker in the woods reading her compass to determine which direction to go The contact would be her holding the compass and moving around the non-contact would be the compass arrow turning every time she moves.
For D: The child on a sled for the contact force would be the person pushing the little kid down the hill the non-contact force would be the gravity that would be keeping the kid going down the hill and gravity stopping the kid at the bottom of the hill.

A neutral hydrogen atom is a special case as it can accept, remove, OR share
electrons during reactions with other atoms. If the electron is removed from
hydrogen, the remaining positive proton number in the atom is 1 and remaining
negative electron number is?
Answer:
The remaining negative electron number is 0.
Explanation:
1 - 1 = 0 since hydrogen has exactly 1 electron. The charge must be balanced if it is a neutral atom. The 1 electron got peeled off and the remaining number is 0. That means the hydrogen atom is a proton now.

Answer:
mass of hydrogen in lake = 11.19% of 12
= 1.3428
check if question is correct or not
Explanation:
Water is 11.19% hydrogen and 88.1% oxygen by mass. Lake superior contains about 1.2x10 kg of water the mass of hydrogen is 1.32 kg
What is mass?Mass is defined as a unit of measurement that describes the amount of matter that makeup an object.
It can also be defined as quantitative measures of inertia, fundamental properties of all matter. It is a dimensionless quantity.
As given 11.19% hydrogen is present in 1.2 x 10 kg
So, the mass of hydrogen = 11.198 % of 1.2 x 10 kg
= 11.19 / 100 x 12
= 1.32 kg
Thus, water is 11.19% hydrogen and 88.1% oxygen by mass. Lake superior contains about 1.2x10 kg of water the mass of hydrogen is 1.32 kg.

difference between halogens and group 0 elements
Answer:
Colourless. Although they have similar properties they are not identical. For example, as you descend Group 0 the density of the gas increases as does the mass of a single atom. ... All the halogens exist as molecules, bonding covalently to their own atoms - adding stability as they complete their full outer shells.The difference between halogens and group 0 elements is that in their electronic configurations the halogens have 1 electron less than the stable octet while the zero group elements have stable octet.
What is electronic configuration?Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.
