Chemical element playing cards

[0015] Example 1 Composition of playing cards:

[0016] A chemical element playing card for learning and consolidating chemical knowledge in the game. This chemical element playing card fully embodies the smallest particles of atoms in chemical changes, and intuitively expresses that the essence of chemical reactions is the rearrangement and recombination of atoms, which embodies some atoms and other microscopic particles.

[0017] The chemical element playing card has a total of 80 cards. The front of each card is composed of atoms of common chemical elements in middle school chemistry, involving more than 20 common chemical elements. The back of each card is a picture of chemical experiment equipment commonly used in middle school. , Is for students to understand and familiarize with common chemical instruments.

[0018] The upper left corner of the front of each card is the atomic symbol of various elements. The content in the parenthesis below the atomic symbol is the same as the content in the lower right corner (the content is the same, but the angle is different by 180 degrees). The lower right corner is the number used when writing chemical formulas. And some symbols such as gas (↑) and precipitation (↓). The middle part of the front of the card is the number of protons of the atom, the nature and characteristics of the atom of the element (atomic structure diagram, valence, etc.), as well as common substances containing the element, the The purpose of the element, etc., let students understand the element in detail.

[0019] You can also use ethnic languages ​​for comparison and annotation, and you can add other decorative borders and so on.

[0020] See Table 1 for the details of 80 playing cards.

[0024] Example 2: How to play:

[0025] It can be played by one player, such as a card game, or two or more players, such as competing for the top.

[0026] The gameplay is similar to ordinary poker. It can form chemical formulas or chemical equations, and can also form chain cards (for example: three or more cards with successively increasing proton numbers), pair (two identical atoms on the front of the card) Card), kill (a card with exactly three atoms on the front of the card), positive kill (a card with four atoms on the front of the card), and have the characteristics of atoms or matter to play (for example: in the core of the earth The highest content is O, followed by Si, and the third is Al). You can also decide your own gameplay based on valence, electronic layer structure, metallicity, non-metallicity, activity, etc.

[0027] First provide a kind of open card game rules:

[0028] The main principle is that the chemical formula must be composed (the actual atom symbol in the upper left corner and the number or symbol in the lower left corner form the chemical formula, for example, to form H 2 O as an example, we need a card with an H in the upper left corner, a card with a 2 in the lower right corner, and a card with an O in the upper left corner to form an H 2 O).

[0029] Arrange the cards in 11 rows, with 1 card in the first row, 2 cards in the second row, 3 cards in the third row, 4 cards in the fourth row, 5 cards in the fifth row, 6 cards in the sixth row, 7 cards in the seventh row, 8 cards in the eighth row, 9 cards in the ninth row, 10 cards in the tenth row, 11 cards in the eleventh row, row to ten is the back side, and the eleventh row is the front side Up, there are 66 cards in this row. The remaining 14 cards are placed together in another place with the back facing up.

[0030] Start to compose the chemical formula, pay attention to the order, first combine the 11 cards in the eleventh row, and put the card with the combined chemical formula in another place.

[0031] When the chemical formula can no longer be combined in the eleventh row, the reverse sign is reversed, and the chemical formula is combined. When the chemical formula cannot be formed, take the remaining 14 cards to form the chemical formula.

[0032] Combine all the cards into a chemical formula to get 80 points, and one point will be deducted

[0033] Continue to provide a kind of competition rules:
