Answer:
5. All magnesium atoms have the same number of neutrons
Explanation:
Magnesium (Mg) is a chemical element. Its atomic number (Z) is 12 (number of protons in the nucleus of the Mg atom).
The Magnesium has three stable isotopes: 24Mg, 25Mg and 26Mg. All these isoforms have 12 protons in their atoms (same atomic number), however they vary in the mass number of the atom (M).
The mass number of the atom (M) is equal to the sum of protons and neutrons in the nucleus.
Based on this information we can know how many neutrons each isotope has
24 Mg = 12 protones + 12 neutrons
25Mg = 12 protones + 13 neutrons
26Mg = 12 protones + 14 neutrons
In this way we conclude that <u>not all magnesium atoms have the same number of neutrons</u>

<h2>Becoming a Cartographer</h2>
Becoming a cartographer can be a rewarding career that helps share important geographical information. Here are some requirements for becoming a cartographer
<h2>Cartographer Education</h2>
The minimum educational requirement to become a cartographer is a bachelor's degree. Cartographers typically study cartography, geography, earth science, surveying or other related fields. Students also tend to get a specialization and training in a Geographic Information System (GIS), the computer system cartographers use to store and analyze collected data.

Explanation:
protons have a positive charge and neutron does not have any charge. both proton and neutron are situated in the. nucleus
Explanation:
Each section of the electromagnetic (EM) spectrum has characteristic energy levels, wavelengths, and frequencies associated with its photons. Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.
Answer:
Fertilization
Explanation:
Egg and sperm are cells known as gametes produced by the GAMETOPHYTE of a sexually-reproducing organism via meiosis. Since egg and sperm cells are produced through meiotic division, their chromosomal number is reduced by half of the parental organism. Hence, sperms and eggs are haploid cells (n) produced by a diploid organism (2n).
Sperm is the male gamete while egg is the female gamete. These two haploid gametes fuse in a process called FERTILIZATION, to produce a diploid ZYGOTE that eventually grows into the diploid structure of the organism called SPOROPHYTE. This system of reproduction called ALTERNATION OF GENERATIONS is used by lower and higher plants.
