What is a plus 3a-2 plus 3a simplified?
7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a
P equals b plus 3a plus c solve for b?
p=b+3a+c p-3a-c=b+3a-3a+c-c p-3a-c=b b=p-3a-c
How do you do this A x 3 a plus 12?
Simplifying a = 3a + 12 Reorder the terms: a = 12 + 3a Solving a = 12 + 3a Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-3a' to each side of the equation. a + -3a = 12 + 3a + -3a Combine like terms: a + -3a = -2a -2a = 12 + 3a + -3a Combine like terms: 3a + -3a = 0 -2a = 12 + 0 -2a = 12 Divide each side by '-2'. a = -6 Simplifying a = -6
What is 3a - 6 when a equals 3?
(3 x 3) - 6 = 3 3a-6=3 3a=3+6 3a=9 a=9/3 a=3
What is 3a-7 equals -28?
3a - 7 = -28 Therefore, 3a = -21 a = -21/3 Therefore, a = -7
How many unpaired electrons are there in an element in group 3A?
In group 3A elements, or elements in group 13, have only one unpaired electrons.
Which of the group 3A elements is the heaviest?
Thallium
Which element has the largest atomic radius in group 3A?
The element in group 3A with the largest atomic radius is thallium (Tl). As you move down a group on the periodic table, the atomic radius tends to increase due to the addition of more electron shells. Thallium, being lower in the group, will have a larger atomic radius compared to other elements in group 3A.
Which of the group 3A elements has the largest ionization energy?
Beryllium is the group 3A element with the highest ionization energy.
Are Group 3A elements the alkaline earth metals?
No, Group 3A elements are not alkaline earth metals. Group 3A elements include boron, aluminium, gallium, indium, and thallium. Alkaline earth metals are found in Group 2A of the periodic table, such as calcium and magnesium.
Are group 3A elements known as alkaline earth metals?
No,but group 2 are alkaline earth elements
How many valence electrons are in the dot structure or the elements in 3A?
Elements in group 3A (also known as group 13) have 3 valence electrons in their dot structures. These elements include boron, aluminum, gallium, indium, and thallium.
What element is found in group 3A and period 6?
The element found in group 3A and period 6 is Indium with the atomic number 49. It is a soft, malleable, and ductile metal commonly used in electronics and semiconductors due to its unique properties.
In group 3A of periodic table all elements are metals while Boron is metalloid why is it placed in this group?
Boron is placed in group 3A of the periodic table because it shares similar chemical properties with the other elements in that group. While it does have some properties of metals, such as conductivity, it also exhibits characteristics of nonmetals, making it a metalloid. This placement reflects its intermediate properties between metals and nonmetals.
What element is found in group 3A and period 3?
The element found in group 3A and period 3 of the periodic table is aluminum (Al). It has an atomic number of 13.
What is 3a² 3a²?
3a^2 + 3a^2 = 6a^2 3a^2 - 3a^2 = 0 3a^2 x 3a^2 = 9a^4 3a^2 divided by 3a^2 = 1
Is found in group 3A and period 6?
This element is likely to be Thallium based on its position in group 3A and period 6 of the periodic table. Thallium is a soft, malleable metal that is often used in electronic components and for its toxicity in certain compounds.
