6.941 tells you the nucleon number (total number of protons and neutrons in the nucleus of an atom)
3 tells you the proton number( number of protons in the nucleus of an atom.)
When drawing this you must know the number of protons , electrons, and neutrons of that element. Well in this question, everything’s been given. No. of protons = 3
No. Of electrons = 3 *REMEMBER, NUMBER OF PROTONS AND ELECTRONS ARE EQUAL WHEN THE ELEMENT IS IN ITS ATOMIC FORM.
No. Of neutrons= 4 neutrons. When rounding 6.941, it is 7. Then simply subtract 7-3 to get 4.
Now time to draw this. First you must know the number of electron shells does lithium has. Since lithium is in period 2, it has 2 electron shells.
Then, you must know what is the valence electron of Li. It is 1, since it is a group I element/alkali metal.
Also remember the structure. Electron are surrounding the nucleus of the atom on electron shells while the nucleus is in the center of the atom. Nucleus contains the protons and neutrons. REMEMBER THE FIRST SHELL SHOULD CONTAIN ONLY 2 ELECTRONS WHILE THE SECOND SHELL WITH 8 ELECTRONS AND GO ON.
Hope this helps and if I’m correct can you add me to the brainliest?
I think it is D for mountains form from the movement of tectonic plates which create volcanoes that erupt and form mountains
Answer:
Option D, the number of phenotypes a gene set can produce in the group
Explanation:
The multiple sets of phenotypic data is one of the indicating factors of the linkages groups.
Thus, the higher the number of phenotypes, the higher is the recombination of genes on same chromosome or closely spaced different chromosome. High phenotypic number also represents less distance between the genes on the same or different chromosome due to which high recombinants have been produced. Thus, in a group , the number of phenotypes produced by a gene set depends on the spatial arrangement of genes on a chromosome.
Genes on different chromosomes or that are located far apart on the same chromosome are considered as unlinked genes. Linkage maps are made by finding recombination frequency for several gene pairs.
Option D is correct
The energy from sunlight comes in the form of photons, and this energy is used in the light dependent reactions of photosynthesis. The first function carried out by the photons in energizing electrons in the chlorophyll. The energized electron travels through the electron transport chain and subsequent steps are carried out to utilize this energy to form ATP.
You can distinguish between these solutions by looking at their crystalline structure. They form different structures because one is an ionic bond and the other one is a covalent bond.
Explanation:
- Sodium Chloride (salt) is formed by giving and taking electrons, that is ionic bonding. It happens between a metal and a non-metal
- Sugars are formed between non-metals, where there is only sharing of electrons happened. It is called covalent bonding.
- Covalent bonds are stronger than ionic bonding. Hence, if you keep the solution for an hour, there forms a crystalline structure. It would be different structures since their force of attraction differs.
