the mass number for an atom is numerically equal to which quantity
Answer:
The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in an atom is its mass number minus its atomic number.
Explanation:
protons
The mass number of an atom is its total number of protons and neutrons. Atoms of different elements usually have different mass numbers , but they can be the same. For example, the mass number of argon atoms and calcium atoms can both be 40.

24: 0.0015
25: 200
26: 0.0105
27: 600
28: 4023000
Explanation:
You have to move the decimal the same amount of times as the exponent says.
For example, like with the 6, you move it 2 decimals to the right (since it's positive), and the regular number would be 600.
If a cell has 4 chromosomes at the beginning of meiosis, how many chromosomes will be in each cell at the end of meiosis?
Answer:2. Mitosis would produce identical daughter cells with the same number as the parent cell. Meiosis would product sex cells with one-half the amount of genetic material as the parent cells.
Explanation:
If a cell has 4 chromosomes at the beginning of meiosis then the daughter cell will have TWO chromosomes at the end of meiosis.
Meiosis is a type of reductional cell division by which a parental cell duplicates its genetic material (DNA) and then divides twice to produce four (4) daughter cells having half of the genetic material.These successive cell division cycles are known as Meiosis I and Meiosis II.Meiosis is a sexual mode of reproduction that produces gametes or geminal cells, which fuse during the process of fertilization to form a zygote.
In conclusion, if a cell has 4 chromosomes at the beginning of meiosis then the daughter cell will have TWO chromosomes at the end of meiosis.

Use your knowledge of valence electrons and how they affect bonds to figure out how carbon (Group 14) and oxygen (Group 16)
would be attached to one another. In carbon dioxide (CO2), how is the compound structured? (Use "-" to represent a single
bond and "=" to represent a double bond) (1 point)
C-O-O
O=C-O
C=O-O
O=C=O
Answer: D
Explanation:
O=C=O
Carbon is in group 14 having four valence electrons and oxygen is in group 16 having six valence electrons hence the correct structure of CO2 is O=C=O.
Carbon and oxygen are nonmetals. Nonmetals form compounds by sharing electrons in a covalent bond.Carbon, a group 14 element has four valence electrons while oxygen, a group 16 element has six valence electrons.
Carbon can share four valence electrons with two oxygen atoms in CO2 to form the structure O=C=O. In this way, all the atoms now obey the octet rule.

calcium, strontium and barium are all located in the same column of the periodic table. why is that?
Calcium (Ca), strontium (Sr), and barium (Ba) are all located in the same column of the periodic table because they have similar atomic structure and similar chemical properties
Periodic tableFrom the question, we are to determine why calcium (Ca), strontium (Sr) and barium (Ba) are all located in the same column of the periodic table
The periodic table is a tabular arrangement of chemical elements that is arranged by increasing atomic number and groups elements according to recurring properties.
Elements with similar atomic structure and similar chemical properties appear in the vertical columns. These columns are called groups.
Hence, calcium (Ca), strontium (Sr), and barium (Ba) are all located in the same column of the periodic table because they have similar atomic structure and similar chemical properties
